While the Syrian government says that it did not carry out a "massacre" in Hama on Thursday night (it has insisted all along that the killings that night were a result of clashes between "armed gangs" and government troops trying to protect civilians. But the AP reports that UN findings show that at the very least, fighting extended into homes:

UN observers investigating a reported mass killing in the Syrian village of Tremseh on Saturday found pools of blood in homes and spent bullets, mortars and artillery shells, adding details to what anti-regime activists have called one of the deadliest events of Syria's uprising.

An 11-vehicle convoy of UN observers entered Tremseh on Saturday, home to between six to ten thousand residents and one of a string of small farming villages along the Orontes River northwest of the city of Hama.

Based on its investigation, the team said in a statement that "an attack" took place on 12 July.

UN observers said the violence seemed to target the homes of army defectors and activists, some of which were burned or damaged and had splattered blood and bullet casings inside.

The team also found evidence of artillery shells and mortars as well as assault rifles, the staple of Syria's rebels.

It did not give a casualty figure, but said the team would return on Sunday to continue investigating.
