The Britain-based Syrian Observatory for Human Rights says the government shelling of rebel strongholds in eastern Ghouta, a Damascus suburb, on Saturday killed at least 13 people, including three women and two children.
The activist-run Aleppo Media Center said airstrikes today on a residential area and market in a rebel-controlled district of the contested city killed 12 people, including children.
Syria's Interior Ministry, meanwhile, says mortar shells fired by rebels fell in two neighborhoods in the capital, Damascus, a rare occurrence since a fragile cease-fire took effect in late February.
