BBC News reports air strikes by Syria's air force around Damascus have killed almost 200 people over the past 10 days, activists say. The U.K.-based Syrian Observatory for Human Rights says the strikes were in the Ghouta green belt outside the city, particularly in the suburb of Duma. Rocket attacks launched from parts of the Ghouta by rebel group Army of Islam killed at least 10 people on Tuesday. Meanwhile, Syrian army units and Hezbollah special forces have also retaken areas south of Damascus. An Army of Islam representative said the rocket attacks on government-controlled parts of Damascus were "revenge" for the Syrian military bombing civilian areas. Many of the wounded were taken from the rubble of flattened buildings to medical centers on Tuesday, the Observatory said.
