At least 45 people were killed in heavy bombardment of a besieged Syrian rebel stronghold east of Damascus that also struck a school.
The Syrian Observatory for Human Rights said rockets fired by regime forces rained down on the towns of Douma, Harasta, Saqba and Arbin in the opposition-held Eastern Ghouta region.
At least 10 children and four women were among the dead and dozens of people were wounded, he said.
“One of the air strikes on Douma hit near a school, killing the school’s principal,” said Abdel Rahman.
Observatory head Rami Abdel Rahman said air strikes also hit the towns, but it was unclear whether they were carried out by Syrian or Russian warplanes.
Men carried children across the dust-covered rubble of destroyed buildings in Douma, whose streets were littered with debris and shards of glass, according to a news agency photographer on the scene.
