Meanwhile, an eyewitness in Deraa, speaking to Al Jazeera on Friday from close to the Omari Mosque that has been a focus for the uprising, described a scene of death and devastation.

He confirmed earlier testimony from a separate source of a split in the military forces sent by Assad to lay siege to the city.

The witness said he had collected the names of the dead from different neighbourhoods and counted 25 bodies in his own area.

“Some areas smell really bad due to the bodies rotting in the street. No one can collect them for fear of being shot,” he said, the sound of continuous gunfire audible over the phone. Those bodies which have been collected are being stored in refrigerated lorries, he said.
