The Syrian government has denied carrying out a massacre in Tremseh, where activists claim more than 200 people were killed on Thursday.
State TV broadcast pictures of weapons said to have been seized during what it described as a “military operation” in the village.
The Foreign Ministry said security forces targeted “armed terrorists.”
“What happened in Tremseh, it was clashes with non-government, armed groups,” said Jihad Makdissi, Ministry spokesman.
“We know the timing of what is happening, with the debate at the UN Security Council,” he added.
The Ministry rejected UN claims that security forces used heavy weapons and said 37 fighters were killed.
A team of UN observers travelled to Tremseh on Saturday to try and establish the facts of what happened and who was involved.
“The attacks appeared targeted towards specific homes of activists as well as army defectors,” said Susan Ghosheh, spokeswoman for the United Nations Supervision Mission in Syria (UNSMIS).
“Our UN team observed homes which had pools of blood and blood splatters in some of the rooms, as well as empty bullet cases. There was a wide range of weapons used, including heavy weapons and artillery mortars and small arms.”
UN special envoy Kofi Annan will meet Russian President Vladimir Putin on Tuesday to discuss the situation in Syria.
