Syria crisis: Air strikes not enough, says rebel fighter

Rebel fighters backed by the US in Syria have told the BBC that the US-led coalition faces a backlash over its bombing campaign against Islamic State.

A number of armed groups vetted by America to help fight against the militants say the support they have been given is not enough.

Major Ahmed Al Saud, 13th Division leader, told the BBC's Ian Pannell that he supported Western air strikes, but that they would not be enough to defeat Islamic State militants without co-ordinated fighting on the ground.
