United Nations observers Saturday toured the Syrian village of Tremseh, where a reported massacre - blamed on Bashar Al-Assad's regime forces - this week left more than 200 people dead, a UN official and activists said. Sausan Ghosheh, the spokeswoman for the UN observer mission in Syria, released a statement saying the team had found that the 'attack appeared targeted at specific groups and houses, mainly of army defectors and activists.' 'There were pools of blood and blood spatters in rooms of several homes together with bullet cases.' She said that a 'wide range of weapons were used, including artillery, mortars and small arms.' Abu Ahmed Al-hamawi, a Syrian activist based in Hama, told DPA by phone that the team met with some residents of the village. 'The team took photos of the bombed houses and collected some shrapnel from the houses they visited to help them determine the type of weapons used by the regime forces against the civilians,' Al-hamawi said. The Tremseh massacre, which reportedly occurred Thursday, has drawn an international outcry against Al-Assad government, with UN chief Ban Ki-moon calling for urgent action to stop bloodshed in Syria.
