Beirut — Fresh bombardment by the Syrian regime on Monday killed many civilians in the rebel-held enclave of Eastern Ghouta, including nine members of a same family, a monitor said. Air strikes destroyed a building in Douma, the main town in the Eastern Ghouta area east of Damascus, and buried alive an entire family, the Syrian Observatory for Human Rights said. Nine civilians from a same family were killed in regime air strikes in Douma, after midnight, the head of the Britain-based Observatory, Rami Abdel Rahman, said. Some of the bodies are still stuck in the rubble, he said. An AFP correspondent in Douma said the bombardment had been very heavy overnight and impeded rescuers in their work. The Observatory said another civilian was killed by regime rocket fire in Harasta, an area of Eastern Ghouta which is directly adjacent to the capital's eastern neighborhoods. In Geneva, United Nations Secretary-General Antonio Guterres called on warring sides to implement a 30-day ceasefire across Syria, in line with an appeal by major powers at the weekend. UN aid agencies are ready to deliver life-saving aid and evacuate critically wounded from the rebel-held Damascus enclave of eastern Ghouta, where 400,000 people have been living under siege, Guterres said. Eastern Ghouta cannot wait, it is high time to stop this hell on earth, Guterres told the UN Human Rights Council, which opened its main four-week annual session in Geneva. UN human rights chief Zeid Ra'ad Al-Hussein said air strikes on Eastern Ghouta were continuing on Monday morning. The UN chief hailed the adoption of the resolution last Saturday after days of drawn-out debate, but stressed that Security Council resolutions are only meaningful if they are effectively implemented, and that is why I expect the resolution to be immediately implemented and sustained. — Agencies
