Campaign group Human Rights Watch has accused the Syrian government of committing war crimes even as it was negotiating details of a UN-brokered peace deal. The organization says government forces killed at least 95 civilians and destroyed hundreds of houses during a two-week offensive in the northern region of Idlib in late March and early April. In this video, an HRW researcher visits one of the towns said to be hit hardest by the violence, Taftanaz, and details evidence found there of summary executions carried out on civilians. "While diplomats argued over details of Annan's peace plan, Syrian tanks and helicopters attacked one town in Idlib after another," said Anna Neistat, associate director for program and emergencies at Human Rights Watch. "Everywhere we went, we saw burnt and destroyed houses, shops, and cars, and heard from people whose relatives were killed. It was as if the Syrian government forces used every minute before the ceasefire to cause harm."
