U.N. observers investigating a deadly attack on the Syrian village of Tremseh say they have found signs the assault targeted the homes of specific opponents of the regime.

Activists say more than 150 people were killed in Thursday's massacre.

The team said it could not confirm the toll, but they found evidence a variety of military weapons were used in the assault on the Sunni farming village in Hama Province.

On Friday, U.N. envoy Kofi Annan blamed government forces for what he called “atrocities” in Tremseh. Syrian state media blamed terrorists.

Meanwhile, the opposition Syrian Observatory for Human Rights tells VOA at least 31 people were killed in anti-government violence Saturday across Syria. Activists also say Syrian forces pounded the southern town of Khirbet Ghazaleh.
