MAZAR-I-SHARIF, Afghanistan (Reuters) – At least one Afghan soldier was killed and several American soldiers were wounded in an incident at a base in northern Afghanistan on Saturday, a U.S. military official said.

A spokesman for the U.S. military command in Kabul denied earlier comments by an Afghan official that Americans had been killed, but confirmed that an unspecified number of soldiers had been wounded at Camp Shaheen, the headquarters of the Afghan army’s 209th Corps in the northern city of Mazar-i-Sharif.

At least one Afghan soldier was killed and another wounded, the U.S. official said.

Abdul Qahar Araam, spokesman for the Afghan army’s 209th Corps, had announced that an Afghan soldier shot and killed four U.S. troops inside the base.

The German military heads the multinational advising mission based in Mazar-i-Sharif. A spokeswoman for the German forces at the joint missions command in Potsdam said “according to what we know right now, no Germans were affected”.

Three U.S. soldiers were killed and a fourth wounded on June 11 when an Afghan soldier opened fire on them at a base in eastern Afghanistan’s Nangarhar province.

In April, scores of Afghan soldiers were killed when militants breached security at Camp Shaheen, detonating explosives and shooting hundreds of troops at a mosque and dining hall on the base.

Coalition countries, led by the United States, are considering sending thousands more troops to Afghanistan to help advise and assist Afghan forces struggling against Taliban and Islamic State militants.

U.S. Defense Secretary Jim Mattis said on Monday that he would present options on Afghanistan to President Donald Trump “very soon”.
