Since then, the regime has dispatched snipers, tanks and civilian gunmen to crush dissent.
UN Secretary-General Ban Ki Moon said yesterday that Annan's priority in visiting Syria had been to halt all fighting by government forces and rebels. Ban said a ceasefire should be quickly followed by inclusive talks to resolve the year-long conflict.
Diplomats have said this could prove difficult because opposition leaders have already rejected calls for dialogue, saying only more military aid can stop Assad's deadly crackdown.
The meeting came as opposition activists reported a new government assault on Idlib. The British-based Syrian Observatory for Human Rights reported that the Government was shelling the Idlib region after tanks moved towards the area in recent days.
Reinforcements have been pouring into Idlib for days, including dozens of tanks and armoured personnel carriers, activists said.
Russian Foreign Minister Sergey Lavrov sought to defend his country's stance on the crisis to Arab leaders angered by Moscow's blocking tactics.
Last month Russia and China vetoed a draft UN Security Council resolution that would have supported an Arab League peace plan calling on Assad to hand over his powers.
That brought accusations that Russia was giving Assad diplomatic cover to intensify his crackdown.
"We are not protecting any regimes," Lavrov insisted at a heated session of the Arab League in Cairo. "We are protecting international law ... We are not looking for a special prize or geopolitical interest here." Observer
