Jamal Udeen Al-Harith, born Ronald Fiddler (20 November 1966 – February 2017), also known as Abu-Zakariya al-Britani, was a British terrorist who carried out a suicide bombing in Iraq in February 2017.
Prior to his attack, Jamal was held in extrajudicial detention as a suspected enemy combatant in the United States Guantanamo Bay detainment camps, in Cuba for more than two years. Together with the Tipton Three, he was among five British citizens repatriated in March 2004 and the next day released by British authorities without charge. That year, he was a party to Rasul v. Rumsfeld, which sued the United States government and the military chain of command for its interrogation tactics. The case was finally dismissed in 2009 after being remanded by the United States Supreme Court to the US District Court for the District of Columbia, on grounds of the government officials having had "limited immunity" at the time. In December 2009, the US Supreme Court declined to accept the case for hearing on appeal. The British government paid £1 million to Jamal al-Harith after his release from Guantanamo. He would later go on to carry out a suicide bombing in Iraq in 2017.
He was born Ronald Fiddler in 1966 in Manchester, England, to parents who had migrated from Jamaica. He has a sister Maxine Fiddler. Fiddler attended local schools. He became a web designer, working in Manchester.
In about 1994, Fiddler converted to Islam and officially changed his name to Jamal Udeen Al-Harith.
Several years later, Al-Harith began an Internet relationship with Samantha Cook, who lived in Perth, Australia. He travelled there in early 2000 to meet her in person. She is the daughter of the Australian Senator Peter Cook. After their relationship ended in July 2000, he returned to Manchester and his work.
