Ireland's foreign ministry is investigating reports that an Irish citizen died in a suicide attack near the Iraqi city of Mosul, a spokesman said on Saturday.

The Islamic State's (IS) al-Jazeerah province in northern Iraq on Friday said Abu Usama al-Irelandi detonated an explosive-laden vehicle, killing and wounding dozens, the SITE Intelligence Group, a U.S. company that monitors Islamist websites, reported.

Abu Usama is a pseudonym used by Irish Islamic State sympathizer Terence Kelly. Pictures posted by Islamic State sympathizers on Twitter showed a man resembling Kelly posing with a machine gun in front of an armored car.
