At Least 15 Killed in Syria

Witnesses say Syrian police have killed at least 15 people during a sustained assault on a city in the southern part of the country. Protesters have been centering in an area around a mosque in Daraa, an agricultural city, and police swept in starting in the early morning. The deaths bring the total toll in the region—the center of the largest challenge to Syria’s regime in decades—to 22. Officials have cut off cellphone service in Daraa, set up checkpoints around the city, and surrounded a mosque that’s being used as headquarters for the rebels, who are demanding democratic reforms.
