Two Islamic State Leaders Killed in Syria Air Strike

Two senior Islamic State leaders were killed in an air strike in northeastern Syria on Monday, the Syrian Observatory for Human Rights reported. The Observatory, which gathers its information from an activist network on the ground, identified the leaders as an Iraqi, Abu Osama al-Iraqi, and a Syrian named Amer al-Rafdan. The Observatory said the air strike was believed to have been carried out by the U.S.-led coalition that is targeting Islamic State in Syria and Iraq, though Rami Abdulrahman, who runs the Observatory, said he could not be sure. The Syrian army and militia fighting alongside it are mounting a separate campaign against Islamic State in the region that borders Turkey to the north and Iraq to the east.
