A Syrian activist group says 92 people have been killed in Syria since the start of the U.S.-Russia-brokered ceasefire a week ago. The figure does not include dozens of Syrian soldiers and Islamic State militants killed in the eastern province of Deir el-Zour. The Syrian military said the airstrike enabled an ISIS advance on a hill overlooking the air base. The ceasefire ends hopes for delivery of food and other aid to eastern Aleppo, which is held by rebels battling to topple the Syrian government. "I am pained and disappointed that a United Nations convoy has yet to cross into Syria from Turkey, and safely reach eastern Aleppo," O'Brien said in a statement.
