The Islamic State of Iraq in the Levant (ISIL) has battled with rival opposition fighters in northern Syria, using US-made military vehicles captured from neighbouring Iraq for the first time, a monitoring group said.
ISIL, a splinter group of al-Qaeda which wants to set up an Islamic caliphate encompassing both Iraq and Syria, has made rapid gains in Iraq in the past two weeks, taking control of the northern city of Mosul and major border crossings with Syria.
Its advances in Iraq appear to have spurred on the Syrian branch, which is fighting both the army of President Bashar al-Assad and also rival opposition groups such as the Western-backed Free Syrian Army, a more moderate force.
