International mediator Kofi Annan said on Friday that Syrian forces had used heavy weaponry against the village of Taramseh, site of a massacre in the rebellious Hama region, in violation of its commitments to his peace plan.
In a statement condemning the "atrocities," Annan voiced shock at the "intense fighting, significant casualties, and the confirmed use of heavy weaponry such as artillery, tanks and helicopters."
UN observers deployed in Syria stood ready to go to Taramseh to verify the facts "as and when circumstances permit", but would require freedom of movement to do their job, he said. If confirmed, it would be the worst single incident of violence in 16 months of conflict in which rebels are fighting to topple President Bashar Assad and diplomacy to halt the bloodshed has been stymied by jostling between world powers.
More than 200 Syrians, mostly civilians, lost their lives in the Taramseh massacre, opposition activists said. The Revolution Leadership Council of Hama told Reuters the Sunni Muslim villagewas subjected on Thursday to a barrage of heavy weapons fire before pro-government Alawite militiamen swept in and killed victims one by one.
"More than 220 people fell today in Taramseh. They died from bombardment by tanks and helicopters, artillery shelling and summary executions," the regional opposition group said in a statement on Thursday evening.
Syrian state television said three security personnel had been killed in fighting in Taramseh and it accused "armed terrorist groups" of committing a massacre there.
Fadi Sameh, an opposition activist from Taramseh, said he had left the town before the reported killing spree but was in touch with residents. "It appears that Alawite militiamen from surrounding villages descended on Taramseh after its rebel defenders pulled out, and started killing the people. Whole houses have been destroyed and burned from the shelling.
"Every family in the town seems to have members killed. We have names of men, women and children from countless families," he said, adding many of the bodies were taken to a local mosque.
Ahmed, another local activist, told Reuters: "So far, we have 20 victims recorded with names and 60 bodies at a mosque. There are more bodies in the fields, bodies in the rivers and in houses ... People were trying to flee from the time the shelling started and whole families were killed trying to escape."
The reports could not be independently confirmed. Syrian authorities severely limit access for independent journalists.
Seventy-eight people were shot or stabbed dead or burned alive in the village of Mazraat al-Qubeir, a Sunni hamlet, by fighters of Assad's Alawite sect on June 6, and 108 men, women and children were massacred in the town of Houla on May 25.
Most of Assad's political and military establishment are minority Alawites, who form a branch of Shi'ite Islam. The revolt and the fighters behind it, and the street protesters who launched the revolt in March 2011, are mostly Sunni Muslims.
While the insurgents have been unable to match the Syrian army's firepower, they have established footholds in towns, cities and villages across Syria, often prompting Assad's forces to respond fiercely with helicopter gunships and artillery.
Defecting ambassador condemns Assad
Earlier on Thursday, the first ambassador to abandon Assad called on the army to "turn your guns on the criminals" of the government as troops backed by tanks swarmed into a suburb of Damascus on Thursday to flush out rebels.
Nawaf al-Fares, a Sunni Muslim who has close ties to the security services, was Syria's ambassador to its neighbor Iraq, one of its few friends in the region.
Coming just days after the desertion of Manaf Tlas, a Sunni brigadier general in the elite Republican Guard who grew up with the president, his defection gave the anti-Assad uprising one of its biggest political lifts.
But Assad's strongest strategic ally, Russia, stuck by him on Thursday with a clear warning to his Western and Arab enemies that it would not even consider calls for a tough new resolution by the UN Security Council in New York.
Britain circulated a draft on Wednesday, backed by the United States, France and Germany, that would make compliance with a transition plan drafted by international envoy Kofi Annan enforceable under Chapter 7 of the UN Charter.
This would allow the council to authorize actions ranging from diplomatic and economic sanctions to military intervention.
British UN Ambassador Mark Lyall Grant raised the fact that another massacre had reportedly taken place during Security Council negotiations on a resolution on Thursday.
"It goes to show that business as usual for the Security Council is not an option. The Security Council, as requested by Kofi Annan, now needs to apply joint and sustained pressure on the parties, with serious consequences for non-compliance," Lyall Grant said in a statement to Reuters.
But as council members began negotiating a resolution to renew the UN Syria monitoring mission, Russia's Deputy UN Ambassador Alexander Pankin warned it would use its veto if it had to. "We are definitely against Chapter 7," he said. "Anything can be negotiated, but we do not negotiate this, this is a red line."
Annan himself asked the 15-member council to agree on "clear consequences" if the Syrian government or opposition failed to comply with his plan, which has produced neither a ceasefire nor political dialogue since it was agreed in April.
The British draft threatens the Syrian government with sanctions unless it stops using heavy weapons and withdraws its troops from towns and cities within 10 days.
