Syria's Defense Ministry has announced a ceasefire after three days of clashes between government forces and Kurdish fighters in Aleppo. The ceasefire began Friday in specific neighborhoods, allowing armed groups six hours to leave with personal weapons. There was no immediate response from the Kurdish-led Syrian Democratic Forces, while a local Kurdish council has rejected calls for the evacuation of fighters. Fighting since Tuesday has displaced 142,000 people, with civilian casualties reported on both sides. The clashes occurred amid stalled political negotiations between the Syrian government and the Kurdish-led Syrian Democratic Forces. The U.S. has been working to extend the ceasefire beyond its initial deadline.
