At least 28 people were killed Sunday in air strikes on a Syrian school district and other sites in a Damascus suburb.
Two children and a school principal were among those killed in the town of Douma, about 15 kilometers (9.3 miles) northeast of the capital, according to the Syrian Observatory for Human Rights (SOHR), an independent U.K.-based monitor.
Syria’s state news agency SANA said at least three civilians were killed and 30 wounded by mortar attacks in Damascus neighborhoods.
SOHR said at least three 31 people were killed Sunday in air strikes on Douma and nearby Eastern Ghouta. The area, known as an insurgent stronghold, has been under Syrian army bombardment for months.
It is unclear who is responsible for the air strikes.
