The leader of the Al Nusrah Front for the People of the Levant, al Qaeda’s branch in Syria, warned the Islamic State of Iraq and the Sham to end its attacks on jihadist and rebel units in Syria or the groups will destroy the ISIS in both Syria and in Iraq. The statement by Al Nusrah emir Abu Muhammad al Julani took place after Ayman al Zawahiri’s emissary was killed in a suicide attack over the weekend.

Al Julani made the threats in an audiotape that was released by the Al Nusrah Front today. His ultimatum gave ISIS five days to come to an agreement or face a concerted effort to “banish it” from both Syria and Iraq. Al Qaeda’s general command recently disowned ISIS as it would not agree to mediate its disputes with the Al Nusrah Front and other groups. The ISIS has been clashing with the Al Nusrah Front, the Islamic Front, and remnants of the Free Syrian Army in several provinces.

“If you refuse God’s ruling, and do not cease afflicting the ummah (Muslim community), it will act against this aggressive, ignorant way of thinking and banish it – even from Iraq,” al Julani warned the ISIS, according to the BBC, which obtained the statement.
