Video: Syrian insurgents claim to attack tank in Homs Video uploaded to a social media website shows the blackened remains of a vehicle still burning, after reportedly being attacked by the Free Syrian Army in Homs on Thursday. The British-based Syrian Observatory for Human Rights said at least 21 people were killed across Syria on the same day. The attack comes as protests in support of the Free Syrian Army erupted in Aleppo, Deir al-Zour, Homs, Idlib and suburbs of Damascus after Friday prayers. Violence is mounting across the country despite the presence of more than 160 Arab League monitors who are trying to verify the implementation of a peace initiative.
