The Islamic State has ordered rival Sunni militant groups in Iraq to lay down their arms and swear allegiance.
After two days of negotiations in Mosul, the Islamic State told the other Sunni groups that they must take an oath of allegiance to the new caliphate, sources told the British Broadcasting Corporation.
Only fighters from the Islamic State will be allowed to carry weapons, the sources said.
The radical al-Qaida breakaway group, the Islamic State of Iraq and Syria, announced on Sunday that it was renaming itself the Islamic State and declaring a caliphate, or transnational Islamic government.
The group's mysterious leader, Abu Bakr al-Baghdadi, was named caliph, or leader of the caliphate.
As a senior Sunni rebel source told the BBC, "Our revolution has been hijacked."
