More than 200 Syrians, mostly civilians, have been massacred by forces loyal to president Bashar al-Assad, according to opposition activists.
It is claimed that the village of Taramseh was bombarded by helicopter gunships and tanks, before militiamen swept in and killed victims one by one.
Syrian state TV blamed “armed terrorist groups” for the deaths, which happened around 10 kilometres from the city of Hama.
Meanwhile, Russia – which has repeatedly defended President Assad – says it wants UN special envoy Kofi Annan to work more closely with the Syrian opposition.
It held talks with opposition leaders this week, who lashed out at the international community for failing to stop the bloodshed in Syria.
Annan is expected to travel to Moscow on Monday for a meeting with Russia’s foreign minister.
