( CNN ) A suicide bomb attack in Iraq this week was carried out by an American jihadist , ISIS claims . The terrorist group released a photograph on Tuesday of a masked fighter it identified as Abu Daood Al-Amriki , an alleged American jihadist who committed the suicide attack . The claim grabbed headlines , but days later , neither CNN nor U.S. government officials have been able to confirm the identity of the attacker . ISIS claims the attacker used an explosives-laden vehicle to mount an attack in Samarra , Iraq . Two senior Iraqi security officials confirmed that an attack matching the description did take place -- that a suicide attacker rammed a vehicle packed with explosives into a convoy of Iraqi forces . At least three Iraqi security forces were killed in the attack , the sources said . But ISIS has not released the birth name of the alleged American suicide bomber , or shown his face . U.S. officials tell CNN that for the moment there is nothing to corroborate the claim .
turkey claims a suicide bombing in turkey was carried out by an American . The claim has not been confirmed .
