Despite an UN Security Council-approved an immediate ceasefire in Syria on Saturday, the regime has reportedly carried out fresh airstrikes in eastern Ghouta, the Syrian Observatory for Human Rights reported. Director of the Syrian Observatory for Human Rights Rami Abdulrahman said: "Air raids resumed at 7.30 am with two raids targeting a region in the suburbs of Duma." More than 500 civilians have been killed in regime raids in the past week. Assads ally Iran said Sunday the attacks would continue on Damascus suburbs held by "terrorists." The United Nations called on Tuesday for an immediate humanitarian ceasefire in Syria of at least a month as heavy air strikes were reported to have killed dozens. UN Security Council unanimously approved late on Saturday the resolution demanding a 30-day ceasefire across Syria to allow the delivery of humanitarian aid. The decision excluded targeting terrorist groups.
