Many countries have become concerned with Russia’s recent military growth in Syria, including Israel.

On Monday, Israel’s Prime Minister Benjamin Netanyahu met with Russian President Putin in Moscow to discuss the global terrorist threat and a plan on peace for the Middle East. The meeting ended with Israel and Russia agreeing to coordinate their military actions to avoid trading fire, according to Netanyahu.

Netanyahu did not elaborate to the media on the agreement, but did say he wanted to achieve the goal of “prevent(ing) misunderstandings between IDF (Israel Defense Force) units and Russian forces” in Syria, where Putin’s ally, Assad, is fighting a civil war with Islamist-dominated insurgents.

Putin stated that Russia would continue to provide military support to Assad in Syria’s fight against the spread of the Islamic State influence. He added that the assistance that has been provided so far is within international law.

Prime Minister Netanyahu informed reporters that he would be sharing the details of his visit with the United States. Currently the U.S. has stopped flying missions against the Islamic State insurgents in Syria until U.S. and Russian leaders meet.

A former adviser to Netanyahu reported that Israel was concerned that Russia’s help to Assad could strengthen Russia’s relationship with Iran, Assad’s other financial backer and Hezbollah patron. This could possibly create an alliance between Russia, Iran, and Hezbollah, resulting in Russia’s technology being given to the terrorist organization.

Netanyahu warned Putin that keeping weapons from Hezbollah was his top priority, and informed Putin of Israel’s policy to strike at guerrillas suspected to attack from the northern frontier of Syria.
