Syrian rebel groups battle each other in north
Al-Qaeda militants battled fighters linked to the Western-backed opposition along with Kurdish gunmen in Syrian towns along the Turkish border on Friday, in clashes that killed at least 19 people, activists said.
The violence is part of an outburst of infighting among the myriad rebel groups opposed to Syrian President Bashar Assad for control over prized border areas. Islamic extremist fighters and more mainstream rebels are increasingly turning their guns on each other in what has effectively become a war within a war in northern and eastern Syria, leaving hundreds dead on both sides.
