The leader of the al-Qaeda-affiliated rebel group in Syria has given rival jihadists an ultimatum to accept arbitration by clerics or be expelled.
Abu Mohammed al-Julani of the al-Nusra Front warned the Islamic State of Iraq in the Levant (ISIS) that it would be driven from Syria and "even from Iraq" if it did not comply within five days.
The threat came after the killing of an al-Qaeda emissary, Abu Khaled al-Suri.
He had reportedly been sent to end the clashes between ISIS and other rebels.
More than 2,000 people are believed to have been killed since Western-backed and Islamist groups attacked ISIS strongholds in early January.
The group's predominantly foreign fighters have been condemned for attacking fellow rebels and abusing civilian supporters of the opposition.
