Syria conflict: Rebel-on-rebel clashes spread in north

[pampango]

Fighting in northern Syria between rival rebel groups has spread to the city of Raqqa, reports say. The powerful al-Qaeda-affiliated group Islamic State in Iraq and the Levant (ISIS) came under attack at its headquarters overnight, activists say.

A coalition of moderates and other Islamists fighting to depose President Bashar al-Assad is ranged against ISIS in several parts of northern Syria. Though they differ on many issues, correspondents say those who make up the alliance appear united in their hatred of ISIS, which includes many foreign jihadists.

ISIS is active in the northern city of Aleppo, but threatened two days ago to quit the battle against government forces there unless its rivals stopped attacking it.

In neighbouring Iraq, ISIS has taken over much of the city of Fallujah, and the Iraqi government has urged residents to expel them or face the prospect of military action.

Not sure what the sudden escalation of attacks by the "coalition of moderates and other Islamists fighting to depose President Bashar al-Assad ranged against ISIS". For a long time momentum seemed to be hugely on the side of the ISIS and other al Queda factions. New weapons? Jockeying for position ahead of the international conference?
