A former Guantanamo Bay inmate who won a compensation after suing over his detention reportedly carried out a suicide bombing at a military base in Iraq.
A statement released by the militant group said a fighter it identified as Abu Zakariya al-Britani was behind a truck attack near Mosul on Sunday. It included a photograph of the alleged bomber. However, NBC News has been unable to verify whether the attack actually occurred.
NBC News has confirmed that the family of Jamal al-Harith identified him as the man in the picture distributed by ISIS that is said was al-Britani.
Born Ronald Fiddler, al-Harith is a 50-year-old British citizen and Muslim convert who was released from Guantanamo Bay in 2004.
Two British security officials told The Associated Press that the man in the ISIS photo was al-Harith. Reuters cited three Western security sources as saying it was highly likely that al-Britani was the bomber and now dead. NBC News was not able to independently confirm those accounts.
