Assad Losing Control in the North and East of Syria

Rebels have been enjoying strategic victories recently

(Reuters) - Rebel strikes against military bases across Syria have exposed President Bashar al-Assad's weakening grip in the north and east of the country and left his power base in Damascus vulnerable to the increasingly potent opposition forces.

Rebel fighters, who have taken at least five army and air installations in the last 10 days, are still waging an asymmetrical war against a powerful army backed by devastating air power, and predict months of conflict still lie ahead.
