UN Chief Establishing Inquiry into Attacks on Civilian Targets in Syria's Idlib Margaret Besheer UNITED NATIONS - U.N. Secretary-General António Guterres announced Thursday that he is setting up an internal inquiry into attacks in a de-escalation zone in northwest Syria, where numerous hospitals have been targeted in recent months. "I believe that this inquiry can produce an important result," Guterres told reporters. "I can guarantee that everything will be done to make sure that this board of inquiry acts with full objectivity, not to prove anything, but to simply say what the truth is." Since the end of April, the government of Syrian President Bashar al-Assad, with support from Russian aircraft, hasstepped up bombing and shelling in the de-escalation zone in Idlib governorate. U.N. humanitarian chief Mark Lowcock said earlier this week that satellite imagery shows 17 villages have been severely damaged and emptied since the military escalation began. He said at least 450 civilians have been killed, including more than 100 in the last two weeks alone, and about 440,000 people have been displaced. .
