The small but powerful al Qaeda-splinter group, the Islamic State in Iraq and the Levant (ISIL) has been caught up in clashes with other insurgents in Syria, including al Qaeda's official Syria branch, the Nusra Front.

The fighting started over power struggles and territorial disputes and has since spread throughout rebel-held territory in Syria.
