Unite Or Risk Death, Al-Qaeda Chief Tells Syrian Rebels

The leader of al-Qaeda has urged warring fighters in Syria to unite or risk death while criticising again the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) group in an audio recording.

In the clip, posted online on Sunday, Ayman al-Zawahiri criticised the UN-backed political process to find a solution in Syria and praised al-Nusra Front, an al-Qaeda offshoot which controls most of Idlib province.
