Syria massacre leaves 200 dead

Some 200 people have been killed in an attack on the Syrian village of Tremseh, opposition activists say.

If confirmed, it would be the bloodiest single event in the Syrian conflict.

Residents said the village, in Hama province, was attacked with helicopter gunships and tanks, and later by the pro-government Shabiha militia, who carried out execution-style killings.
