YEREVAN, JULY 14, ARMENPRESS: The UN said it had confirmed intense fighting including the use of tanks, helicopters and heavy artillery.
The army admitted killing a "big number of terrorists" but said no civilians had died.
Activists initially claimed 200 people including civilians died but later said most of those killed were fighters. If the death toll in Tremseh is confirmed, it would be the bloodiest single event in the Syrian conflict.
Armenpress reports calling Arabian Medias, that the US, France and UK all condemned the violence and called for co-ordinated action from the UN Security Council.
The mandate for the UN's observer mission to Syria expires on 20 July and council members are locked in debate about a new resolution, which must be passed before the deadline if the mission is to be renewed.
