Abu Bakr al-Baghdadi, the leader of ISIS, has put an ultimatum on foreign fighters to either return home or conduct suicide attacks against Iraqi forces in Mosul with the promise of going to heaven and being rewarded with 72 virgins, a local source in Nineveh province told Al-Sumaria News on Monday.

ISIS are known to execute fighters who try to leave the terrorist group.

It is assumed that their encouragement to return to their home countries would be to carry out attacks or start their own insurgencies.
