BEIRUT: The United States has accused the Syrian military of carrying out airstrikes to help ISIS fighters advance around the northern city of Aleppo, messages posted on the U.S. Embassy Syria official Twitter feed said.
ISIS fighters pushed back rival insurgents north of Aleppo Sunday near the Turkish border, threatening their supply route to the city, fighters and a group monitoring the war said.
Fighters from Levant Front, a northern alliance which includes Western-backed rebels and Islamist fighters, said they were worried ISIS was heading for the Bab al-Salam crossing between Aleppo and the Turkish province of Kilis.
