‘Border on fire’ as Turkey intensifies Syria campaign

By Daren Butler

ISTANBUL (Reuters) – Turkey stepped up its air and artillery strikes on Kurdish militia in northeast Syria on Friday, escalating an offensive that has drawn warnings of humanitarian catastrophe and turned Republican lawmakers against U.S. President Donald Trump.

The incursion, launched after Trump withdrew U.S. troops who had been fighting alongside Kurdish forces against Islamic State militants, has opened a new front in the eight-year-old Syrian civil war and drawn fierce international criticism.

In Washington, Trump – fending off accusations that he abandoned the Kurds, loyal allies of the United States – suggested that Washington could mediate in the conflict, while also raising the possibility of imposing sanctions on Turkey.

On Friday, Turkish warplanes and artillery struck around Syria’s Ras al Ain, one of two border towns that have been the focus of the offensive. Reuters journalists heard gunfire there from across the frontier in the Turkish town of Ceylanpinar.

A convoy of 20 armored vehicles carrying Turkish-allied Syrian rebels entered Syria from Ceylanpinar. Some made victory signs, shouting “Allahu akbar” (God is greatest) and waving Syrian rebel flags as they advanced towards Ras al Ain.

Some 120 km (75 miles) to the west, Turkish howitzers resumed shelling near the Syrian town of Tel Abyad, a witness said.

“In these moments, Tel Abyad is seeing the most intense battles in three days,” Marvan Qamishlo, a spokesman for the Kurdish-led Syrian Democratic Forces (SDF) said.

Overnight, clashes erupted at different points along the border from Ain Diwar at the Iraqi frontier to Kobani, more than 400 km to the west. Turkish and SDF forces exchanged shelling in Qamishli among other places, the SDF’s Qamishlo said.

“The whole border was on fire,” he said.

Turkish forces have seized nine villages near Ras al Ain and Tel Abyad, said Rami Abdulrahman, director of the Syrian Observatory for Human Rights, which monitors the war.

At least 32 fighters with the SDF and 34 Turkey-backed Syrian rebels have been killed in fighting, while 10 civilians have been killed, Abdulrahman said. The SDF said 22 of its fighters were killed on Wednesday and Thursday.

Turkey says it has killed hundreds of SDF fighters in the operation and one Turkish soldier has been killed.

In Syria’s al Bab, some 150 km west of the offensive, some 500 Turkish-backed Syrian fighters were set to head to Turkey to join the operation, CNN Turk reported. It broadcast video of them performing Muslim prayers in military fatigues, their rifles laid down in front of them, before departing for Turkey.

“HUMANITARIAN CATASTROPHE”

Turkey says the purpose of its assault is to defeat the Kurdish YPG militia, which it sees as an enemy for its links to insurgents in Turkey. It says it aims to set up a “safe zone” inside Syria, where it can resettle many of the 3.6 million refugees it has been hosting.

Turkey’s President Tayyip Erdogan criticized Europe for failing to support the Turkish offensive and threatened to send refugees to Europe if the EU did not back him.

European Council President Donald Tusk responded on Friday by chastising Erdogan for making the threat.

“Turkey must understand that our main concern is that their actions may lead to another humanitarian catastrophe,” he said.

The International Rescue Committee aid group says 64,000 people in Syria have fled in the first days of the campaign.

The Kurdish YPG is the main fighting element of the Syrian Democratic Forces (SDF) which have acted as the principal allies of the United States in a campaign that recaptured territory held by the Islamic State group.

The SDF now holds most of the territory that once made up Islamic State’s “caliphate” in Syria, and has been keeping thousands of Islamic State fighters in jail and tens of thousands of their family members in camps.

A camp sheltering more than 7,000 displaced people in northern Syria is to be evacuated and there are talks on moving a second camp for 13,000 people including Islamic State fighters’ families, after both were shelled, Kurdish-led authorities said.

Medecins Sans Frontieres said a hospital in Tel Abyad had been forced to shut after most of its staff fled from bombings over the past 24 hours.

RARE REPUBLICAN CRITICISM OF TRUMP

In the United States, Trump’s decision to withhold protection from the Kurds has been one of the few issues to prompt criticism from his fellow Republicans, including leading allies on Capitol Hill such as Senator Lindsey Graham.

Trump said in a Twitter post on Thursday: “We have one of three choices: Send in thousands of troops and win Militarily, hit Turkey very hard Financially and with Sanctions, or mediate a deal between Turkey and the Kurds!”.

“I hope we can mediate,” Trump said when asked about the options by reporters at the White House.

Without elaborating, he said the United States was “going to possibly do something very, very tough with respect to sanctions and other financial things” against Turkey.

Western countries’ rejection of the Turkish offensive creates a rift within the NATO alliance, in which Turkey is the main Muslim member.

NATO Secretary General Jens Stoltenberg said after talks with Foreign Minister Mevlut Cavusoglu in Istanbul that he expected Turkey to act with restraint in Syria. Cavusoglu said Ankara expected “strong solidarity” from the alliance.

Stoltenberg also told reporters the international community must find a sustainable solution for Islamic State prisoners in Syria.

French Foreign Minister Jean-Yves Le Drian has called for an emergency meeting of the U.S.-led coalition of more than 30 countries created to fight Islamic State. France’s European affairs minister said next week’s EU summit will discuss sanctions on Turkey over its action in Syria.

Russian President Vladimir Putin warned that Islamic State militants could escape from jail as a result of the Turkish offensive, the Interfax news agency reported.

Human Rights Watch: Turkey-backed forces seizing property in Syria’s Afrin

BEIRUT (Reuters) – Turkey-backed rebels in northwest Syria’s Afrin have seized, looted and destroyed Kurdish civilians’ property after taking control of the region in March, Human Rights Watch said on Thursday.

Turkey’s military and its Syrian rebel allies launched a cross-border operation into Syria earlier this year and drove fighters from the Syrian Kurdish YPG militia out of the town of Afrin and the surrounding area.

Ankara sees the YPG as a terrorist group and an extension of the outlawed Kurdistan Workers Party (PKK), which has waged a three-decade insurgency on Turkish soil. Turkey has threatened to drive the YPG from the entire length of its border.

The United Nations said 137,000 people were displaced by the Afrin offensive, another large population movement in the seven-year long Syrian conflict which has forced more than half of the country’s pre-war population from their homes.

Rights group HRW interviewed people who had been displaced from Afrin. They accuse Turkey-backed forces of moving their fighters and people from other parts of Syria into vacated homes and of taking over business premises without paying compensation.

One interviewee, Roni Seydo, left Afrin in March but was told by a friend that an armed group had taken over his house, painting the word “seized” on the outside wall.

He said his neighbors were questioned about his family and it possible links with the PKK.

Another former Afrin resident, photographer Ser Hussein, said one of his two studios was burned down and the other turned into a butchers shop.

“Those who made the decision to take over Afrin also took on the responsibility of ensuring that both the residents of Afrin, and people there who have been displaced elsewhere have basic shelter in a way that doesn’t infringe on either of those groups’ rights,” HRW’s acting emergencies director Priyanka Motaparthy said in a report.

“So far it seems that they are failing to do the right thing by either group.”

Under the laws of war, pillaging, or forcibly taking private property for personal use is prohibited and can constitute a war crime, HRW said. The laws of war also prohibit destruction of property not justified by military necessity.

HRW said owners should be compensated for the use and damage of their property and the rights of rights of owners and returnees should be guaranteed.

Reuters was not immediately able to reach the rebel groups for comment.

HRW said the Free Syrian Army rebel umbrella group issued a statement on March 9 inviting Afrin residents to submit complaints to the military headquarters in Azaz to claim their looted property.

HRW also said rebel faction Ahrar al-Sharqiyah issued a statement on April 20 denying responsibility for property violations and looting and saying it had arrested several people who may have been involved in such acts.

Turkish officials in March said they were looking into allegations of looting and property seizure and that they would ensure Afrin would be a safe place for residents to return to.

Syrian rebel fighters pull out of their last besieged area

BEIRUT (Reuters) – The remaining fighters started to withdraw from the last rebel-held enclave in central Syria on Wednesday, state television reported, sealing the government’s control over the area and opening a major stretch of the country’s most important highway.

It further cements President Bashar al-Assad’s dominant position over the most populated parts of Syria after years of fighting, but means any new military campaign might risk direct conflict with foreign powers.

The withdrawal may also be the last in a series of agreed evacuations used by the government to defeat besieged insurgents by forcing them to surrender territory in return for safe passage to opposition areas in the north.

Often brokered by Assad’s Russian allies, such agreements have in recent years become a defining characteristic of Syria’s seven-year war.

In the last two months alone, the United Nations says 110,000 people have been evacuated to northwestern Syria and rebel-held areas north of Aleppo.

The opposition has called it a policy of forced displacement amounting to demographic change to force out Assad’s opponents. The Syrian government has said nobody is forced to leave and those who stay must accept state rule.

The last besieged rebel area, being fully evacuated on Wednesday, is the large enclave located between the cities of Hama and Homs around the towns of Rastan, Talbiseh and Houla.

Rebels still hold large swathes of northwest and southwest Syria that are not besieged because they border Turkey and Jordan, which have at times backed the insurgents and are guarantors of limited truces in those areas.

The only other area still surrounded by the Syrian army, in the Yarmouk Palestinian refugee camp south of Damascus, is held by Islamic State fighters who look unlikely to agree to withdraw to the patch of desert they still hold in east Syria.

More than a quarter of Syria is held by an alliance of Kurdish and Arab militias that the United States helped in the fight against Islamic State.

U.S. President Donald Trump has said he wants to pull American troops from Syria, but the Pentagon has said they are staying for now.

SIEGE

Assad focused on the remaining besieged rebel pockets last month after taking back Eastern Ghouta, the biggest insurgent enclave near Damascus, in a ferocious, weeks-long offensive.

Having held the area being evacuated on Wednesday for years, rebels agreed earlier this month to withdraw along with their families and other civilians who did not want to come back under Assad’s rule.

Since the enclave straddled Syria’s main north-south highway in the stretch between Hama and Homs, recapturing it will significantly ease communication lines in government areas.

Some 27,000 people have left the enclave already since the evacuations began earlier this month, a local government official said. The last convoy of buses began to leave on Wednesday, according to state media.

Last month, 66,000 people left Eastern Ghouta under similar agreements, the U.N. has said. Other major evacuations have included from east Aleppo in late 2016, when more than 30,000 people left.

Tens of thousands of other people have left smaller pockets in recent years. It has added to a humanitarian crisis in northwestern Idlib province, where the pre-war population of about 1 million people has been doubled by those fleeing other parts of the country.

U.S. and Turkey agree to mend ties; Turks propose joint deployment in Syria

ANKARA (Reuters) – The United States and Turkey agreed on Friday to try to rescue a strategic relationship that Washington acknowledged had reached a crisis point, with Turkey proposing a joint deployment in Syria if a U.S.-backed Kurdish militia leaves a border area.

U.S. Secretary of State Rex Tillerson met President Tayyip Erdogan during a two-day visit that followed weeks of escalating anti-American rhetoric from the Turkish government.

While relations between Washington and its main Muslim ally in NATO have been strained by a number of issues, Turkey has been particularly infuriated by U.S. support for the Syrian Kurdish YPG militia, which it sees as terrorists.

Turkey launched an air and ground assault last month in Syria’s northwest Afrin region to sweep the YPG away from its southern border. The United States has armed, trained and aided YPG fighters with air support and special forces, as the main ground force in its campaign against Islamic State.

“We find ourselves at a bit of a crisis point in the relationship,” Tillerson told a news conference after meeting with Foreign Minister Mevlut Cavusoglu on Friday morning. He had met with Erdogan for a more than three-hour discussion on Thursday night.

“We’re going to act together from this point forward. We’re going to lock arms. We’re going to work through the issues that are causing difficulties for us and we’re going to resolve them.”

The United States has no troops on the ground in Afrin, where the Turkish offensive has so far taken place. But Turkey has proposed extending its campaign further east to the town of Manbij, where U.S. troops are based, potentially leading to direct confrontation with U.S.-backed units.

In a proposal that could signal an important breakthrough in efforts to overcome the allies’ stark differences over Syria, a Turkish official told Reuters that Turkey had proposed that Turkish and U.S. forces could deploy jointly in Manbij.

Such a joint deployment could take place if YPG fighters first withdrew to positions east of the Euphrates river, long a Turkish demand.

Neither Tillerson nor Cavusoglu, the Turkish foreign minister, directly responded to a question about Reuters’ report of a possible joint deployment to Manbij.

MANBIJ

Turkey would be able to take joint steps with the United States in Syria once the YPG left the vicinity of Manbij, Cavusoglu told reporters.

“What is important is who will govern and provide security to these areas,” he said. “We will coordinate to restore stability in Manbij and other cities. We will start with Manbij. After YPG leaves there, we can take steps with the U.S. based on trust.”

He also said the two countries had created a “mechanism” for further talks and would meet again by mid-March to further hash out their differences. Tillerson said issues around Manbij would receive priority in the talks, acknowledging Washington had not fufilled some of its promises to Turkey on Manbij.

“The United States made commitments to Turkey previously, we’ve not completed fulfilling those commitments. Through the working group, we’re going to address that and Manbij is going to receive priority,” he said.

Turkey’s pro-government media has been particularly scathing of the United States over its failure to keep a promise that the YPG would leave the town once Islamic State was defeated there.

“But it’s not just Manbij. We have to think about all of northern Syria,” Tillerson said.

Tillerson said he recognized Turkey’s legitimate right to defend its borders, but called on Ankara to show restraint in the Afrin operation and avoid actions that would escalate tensions in the area.

He also said the United States had serious concerns about local employees at its missions in Turkey and called on Ankara to release a U.S. pastor and other Americans detained in Turkey.

Turkey demands U.S. expel Kurdish militia from anti-Islamic State force

By Idrees Ali and Robin Emmott

BRUSSELS (Reuters) – Turkey said on Thursday it had demanded that the United States expel a Kurdish militia from the ground forces it backs in Syria, underscoring the widening gulf between the NATO allies since Ankara launched a new Syrian offensive last month.

Ties between Turkey and the United States, both allies in a U.S.-led coalition fighting against Islamic State, have been strained to the breaking point by Washington’s support for the Syrian Kurdish YPG militia, which Ankara sees as terrorists.

The issue is expected to dominate a visit to Turkey by U.S. Secretary of State Rex Tillerson on Thursday and Friday at a time when relations between Washington and Ankara are fraying over a range of other issues as well.

Turkey launched an air and ground operation in northwest Syria’s Afrin region to drive the YPG from its southern border.

Ankara considers the YPG to be an arm of the PKK, a banned group that has waged a decades-long insurgency in Turkey. The YPG is the main ground element of the Syrian Defence Forces (SDF), which the United States has armed, trained and aided with air support and special forces to fight Islamic State.

“We demanded this relationship be ended, I mean we want them to end all the support given to the Syrian arm of PKK, the YPG,” Turkish Defence Minister Nurettin Canikli told reporters in a briefing in Brussels, a day after meeting U.S. Defense Secretary Jim Mattis on the sidelines of a NATO meeting.

“We demanded this structure be removed from SDF,” he said.

Speaking with reporters on the sidelines of the NATO meeting, Mattis said his talks with his Turkish counterpart were open and honest, but acknowledged the differences.

“I believe we are finding common ground and there are areas of uncommon ground, where sometimes war just gives you bad alternatives to choose from…. We continue to collaborate on ways to ensure their legitimate concerns are addressed.”

RENEWED FOCUS

A U.S. statement said Mattis had urged Turkey to keep attention on fighting Islamic State: “He called for a renewed focus on the campaign to defeat ISIS, and to preventing any vestige of the terrorist organization from reconstituting in Syria,” it said, using an acronym for Islamic State.

Islamic State fighters were driven last year from all the population centers they occupied in both Syria and Iraq, but Washington still considers them a threat, capable of carrying out an insurgency and plotting attacks elsewhere.

Ankara has placed greater emphasis in recent months on the need to combat the Kurdish militia and has said the United States is merely using one terrorist group to combat another.

Turkey says the United States has yet to honor several pledges: to stop arming the YPG, to take back arms after Islamic State was defeated in Syria, and to pull YPG forces back from Manbij, a Syrian town about 100 km (60 miles) east of Afrin.

Canikli also said that Mattis had told him the United States was working on a plan to retrieve weapons given to the YPG, especially heavy weapons. However, Tillerson later said that Washington had “never given heavy arms” to the YPG and there was therefore “nothing to take back”.

POWERFUL FRIENDS

Turkey is the main Muslim ally of the United States within NATO and one of Washington’s most powerful friends in the Middle East dating back to the Cold War era. But widening differences on Syria policy are just one of a number of issues that have caused a rupture in that strategic relationship.

It also accuses Washington of sheltering a cleric it blames for plotting a failed coup in 2016. The United States convicted a Turkish banker mast month for violating sanctions on Iran in a case that included testimony alleging corruption by top Turkish officials. The two countries also halted issuing visas for months after locally hired U.S. consular staff were detained on suspicion of links to alleged coup plotters.

The Turkish authorities have jailed tens of thousands of people and ordered 150,000 fired or suspended from their jobs since the failed coup. President Tayyip Erdogan has increasingly used stridently anti-European and anti-American rhetoric.

The Turkish offensive against the YPG in Syria has so far been limited to Afrin, a border region where the United States is not believed to have troops on the ground. But Turkey has openly discussed extending it to other areas where its forces could potentially come into contact with units supported by the Americans. It says Washington should pull its forces out of the way; the United States says it has no plans to withdraw.

Canikli said he disputed Washington’s characterization of the U.S.-backed SDF as controlled by ethnic Arabs rather than the Kurdish fighters.

“Mattis said the SDF is largely controlled by Arab elements. We said on the contrary, the SDF is completely controlled by the PYD and YPG,” he said in comments broadcast live on television. “The other elements are for show only.”

Blasts kill dozens in Syria as U.S.-Russia truce talks make little progress

Syrian army soldiers inspect the damage at the site of two explosions that hit the Arzouna bridge area at the entrance to Tartous, Syria

By Lisa Barrington and Roberta Rampton

BEIRUT/HANGZHOU, China (Reuters) – Explosions in government-controlled areas of Syria and a province held by Kurdish militia killed dozens on Monday, while the United States and Russia failed to make concrete progress towards a ceasefire.

Six explosions hit west of the capital Damascus, in the government-held cities of Homs and Tartous – which hosts a Russian military base – and the Kurdish-controlled northeastern province of Hasaka between 8 a.m. and 9 a.m. (0500-0600 GMT), state media and a monitor said.

It was not clear if the blasts were linked and there was no immediate claim of responsibility.

More than five years of civil war have cut Syria into a patchwork of territories held by the government and an often competing array of armed factions, including Kurdish militia fighters, a loose coalition of rebels groups, and Islamic State.

The United States and Russia have been trying to broker a new truce after a cessation of hostilities agreed in February unraveled within weeks, with Washington accusing Syrian President Bashar al-Assad’s forces of violating the pact.

Their efforts were complicated on Sunday as government forces and their allies again laid siege to rebel-held eastern Aleppo, Syria’s largest city before the war which Assad is determined to fully recapture. His gains have relied heavily on Russian air support since September last year.

U.S. President Barack Obama and Russian President Vladimir Putin had a longer-than-expected discussion of about 90 minutes on Monday about whether, and how, they could agree a deal, a senior U.S. administration official said.

Meeting at the G20 summit in China, they discussed getting humanitarian aid into the country, reducing violence, and cooperating on combating militant groups, the official said.

But in talks earlier on Monday, U.S. Secretary of State John Kerry and Russian Foreign Minister Sergei Lavrov were unable to come to terms on a ceasefire for the second time in two weeks, with U.S. officials stressing they would walk away if a pact could not be reached soon.

“If an agreement can be reached, we want to do so urgently, because of the humanitarian situation. However, we must ensure that it is an effective agreement,” the official said.

Russia says it cannot agree to a deal unless opposition fighters, backed by the United States and Middle East allies, are separated from al Qaeda-linked militants they overlap with in some areas.

For Washington, the priority is stabilizing Syria so as to destroy Islamic State, which controls territory both there and in neighboring Iraq.

NATO Turkey ally on Sunday said rebels it was backing had gained control of all areas on its border that had been held by the jihadists, depriving the ultra-hardline Islamist group of its main route to the outside world.

The announcement came some 10 days after Turkey launched its first major military incursion into Syria since the start of the war in 2011, an operation aimed as much at preventing further Kurdish territorial gains as at driving back Islamic State.

DOZENS KILLED

Two of the explosions on Monday hit the Arzouna bridge area at the entrance to the Mediterranean city of Tartous, the Syrian Observatory for Human Rights and state news agency SANA said. Islamic State attacked Tartous in May.

The Observatory and a city hospital put the death toll at 35, including members of the Syrian military, and said the number was likely to rise.

Syrian state television said the first explosion was a car bomb and the second a suicide belt detonated as rescue workers arrived. The blasts hit during a summer festival at Tartous, whose beaches recently featured in a government tourism video.

A car bomb meanwhile struck Homs, a city around 80 km (50 miles) east of Tartous which has repeatedly been hit by bombings claimed by Islamic State. State media said three people were killed, while the Observatory said the explosion hit an army checkpoint and four officers were killed.

West of Damascus, there was an explosion near the town of al Saboura, killing one person and injuring three, according to a police commander quoted by state media.

A motorbike also exploded in the centre of the northeastern city of Hasaka, which is controlled by the Kurdish YPG militia.

The Observatory said the blast killed three members of a YPG-affiliated security force known as the Asayish, and injured others. It said a percussion bomb also went off in the province’s Qamishli city.

The Kurdish YPG militia, a critical part of the U.S.-backed campaign against Islamic State, took almost complete control of Hasaka city in late August after a week of fighting with the government.

Islamic State confirmed that a blast in Hasaka took place but did not say whether its fighters were involved.

The YPG already controls swathes of northern Syria where Kurdish groups have established de facto autonomy since the start of the Syrian war in 2011, much to the alarm of neighboring Turkey.

Ankara sees the YPG as an extension of Kurdish militants who have waged a three-decade insurgency in Turkey and fears the creation of a Kurdish enclave in northern Syria would fuel their separatist ambitions.

Turkey fires on U.S.-backed Kurdish militia in Syria offensive

Turkish army tanks and military personnel are stationed in Karkamis on the Turkish-Syrian border in the southeastern Gaziantep province, Turkey,

By Humeyra Pamuk and Umit Bektas

KARKAMIS, Turkey (Reuters) – Turkish troops fired on U.S.-backed Kurdish militia fighters in northern Syria on Thursday, highlighting the complications of an incursion meant to secure the border region against both Islamic State and Kurdish advances.

Syrian rebels backed by Turkish special forces, tanks and warplanes entered Jarablus, one of Islamic State’s last strongholds on the Turkish-Syrian border, on Wednesday.

But President Tayyip Erdogan and senior government officials have made clear the aim of “Operation Euphrates Shield” is as much about stopping the Kurdish YPG militia seizing territory and filling the void left by Islamic State as it is about eliminating the ultra-hardline Islamist group itself.

A Turkish security source said the army shelled the People’s Protection Units (YPG) south of Jarablus. Turkey’s state-run Anadolu agency described the action as warning shots.

Gunfire and explosions echoed around hills in the region on Thursday, a day after the incursion first began.

Some of the blasts were triggered as Turkish security forces cleared mines and booby traps left by retreating Islamic State militants, according to Nuh Kocaaslan, the mayor of Karkamis, which sits just across the border from Jarablus. He said three Turkish-backed Syrian rebels were killed but no Turkish troops.

Turkey, which has NATO’s second biggest armed forces, demanded that the YPG retreat to the east side of the Euphrates river within a week. The Kurdish militia had moved west of the river earlier this month as part of a U.S.-backed operation, now completed, to capture the city of Manbij from Islamic State.

Ankara views the YPG as a threat because of its close links to Kurdish militants waging a three-decade-old insurgency on its own soil. It has been alarmed by the YPG’s gains in northern Syria since the start of the Syrian civil war in 2011, fearing it could extend Kurdish control along Turkish borders and fuel the ambitions of Kurdish insurgents in Turkey.

Turkey’s stance has put it at odds with Washington, which sees the YPG as a rare reliable ally on the ground in Syria, where Washington is trying to defeat Islamic State while also opposing President Bashar al-Assad’s government in a complex, multi-sided, five-year-old civil war.

The Syrian Kurdish force is one of the most powerful militias in Syria and regarded as the backbone of the Syrian Democratic Forces (SDF), a U.S.-backed alliance formed last October to fight Islamic State.

Turkish Defense Minister Fikri Isik said the Kurdish PYD party, the political arm of the YPG, wanted to unite Kurdish-controlled cantons east of Jarablus with those further west. “We cannot let this happen,” he said.

“Islamic State should be completely cleansed, this is an absolute must. But it’s not enough for us … The PYD and the YPG militia should not replace Islamic State there,” Isik told Turkish broadcaster NTV.

EUPHRATES

U.S. Secretary of State John Kerry told Turkish Foreign Minister Mevlut Cavusoglu by phone on Thursday that YPG fighters were retreating to the east side of the Euphrates, as Turkey has demanded, foreign ministry sources in Ankara said.

A spokesman for the U.S.-led coalition against Islamic State said the SDF had withdrawn across the Euphrates, doing so “to prepare for the eventual liberation” of Raqqa, the radical group’s stronghold which lies further east.

Isik said the retreat was not yet complete and Washington had given assurances that this would happen in the next week.

“If the PYD does not retreat to east of the Euphrates, we have the right to do everything about it,” the minister said.

The offensive is Turkey’s first major military operation since a failed July 15 coup shook confidence in its ability to step up the fight against Islamic State. It came four days after a suicide bomber suspected of links to the group killed 54 people at a wedding in the southeastern city of Gaziantep.

U.S. Vice President Joe Biden, who met Erdogan during a trip to Turkey on Wednesday, said Turkey was ready to stay in Syria for as long as it takes to destroy the radical Islamist group.

“I think there has been a gradual mind shift … in Turkey, with the realization that ISIL is an existential threat to Turkey,” he told reporters during a visit to Sweden, using an acronym for the militant group.

A Turkish official said the ground incursion had been in the works for more than two years but had been delayed by U.S. reservations, resistance from some Turkish commanders, and a stand-off with Russia which had made air cover impossible.

Turkey had made the case more strongly to Washington over the past few months, had patched up relations with Russia, and had removed some of the Turkish commanders from their posts after finding they were involved in the coup attempt, paving the way for the operation to go ahead, the official said.

The incursion comes at a testing time for Turkish-U.S. relations. Erdogan wants the United States to extradite Fethullah Gulen, a Turkish cleric who has lived in self-imposed exile in Pennsylvania for 17 years and whose religious movement Turkey blames for staging last month’s failed coup.

Washington says it needs clear evidence of Gulen’s involvement and that it is a matter for the courts, a position that has sparked an outpouring of anti-Americanism from Turkey’s pro-government media. Gulen denies any role in the coup attempt.

REBELS ADVANCE

The sound of gunfire, audible from a hill on the Turkish side of the border overlooking Jarablus, rang out on Thursday and black smoke rose over the town. War planes flew overhead.

A senior Turkish official said there were now more than 20 Turkish tanks inside Syria and that additional tanks and construction machinery would be sent in as required. A Reuters witness saw at least nine tanks enter on Thursday, and 10 more were waiting outside a military outpost on the Turkish side.

“We need construction machinery to open up roads … and we may need more in the days ahead. We also have armored personnel carriers that could be used on the Syrian side. We may put them into service as needed,” the official said.

Erdogan said on Wednesday that Islamic State had been driven out of Jarablus and that it was now controlled by Turkish-backed Syrian rebels, who are largely Arab and Turkmen.

“The myth that the YPG is the only effective force fighting Islamic State has collapsed,” Erdogan’s spokesman Ibrahim Kalin wrote on Twitter, reflecting Turkish frustration at how closely Washington has been working with the Kurdish militia.

Saleh Muslim, head of the Kurdish PYD, said on Wednesday that Turkey was entering a “quagmire” in Syria and faced defeat there like Islamic State. Redur Xelil, spokesman for the YPG, said the intervention was a “blatant aggression in Syrian internal affairs”.

After seizing Jarablus, the Turkish-backed rebels have advanced up to 10 km (6 miles) south of the border town, rebel sources and a group monitoring the war said.

But the Syrian Observatory for Human Rights also said Kurdish-backed forces opposed by Ankara had gained up to 8 km of ground northwards, apparently seeking to pre-empt advances by the rebels.
