Fresh video evidence has emerged of the military crackdown in Syria.
One film is said to show soliders who have recently defected walking freely among a cheering crowd in the city of Homs.
Human rights campaigners say Syria’s ruling hierarchy has stepped up efforts to crush demonstrations in recent weeks, including more frequent military raids, targeted assassinations of protest leaders and the arrest of thousands of Syrians.
According to activists heavy shelling has taken place in villages and old districts demanding the removal of President Assad. Shocking and disturbing images have also emerged of alleged summary executions of civilians by the army.
It comes as the Arab League announced that its secretary general will visit Syria on Saturday and Arab foreign ministers will meet next week to convey concerns over the crackdown.
