The Syrian government's five-day offensive in the town of Darya on the outskirts of Damascus claimed the lives of at least 320 people, most of them civilians, said Syrian Observatory for Human Rights on Sunday. On Saturday alone, 120 people were killed in Darya when troops recaptured the town from opposing fighters, following heavy shelling, the London-based Observatory said. The Observatory accused President Bashar al-Assad's troops of carrying out "summary executions" in house-to-house raids in the town according to a report of DPA. Opposition activists posted a video on the internet showing the bodies of people they said had been killed by al-Assad's forces in Darya. The footage showed scores of bodies laid out in rows inside mosques and basements.
