Abdurahman Ahmed Said Khadr (Arabic: عبد الرحمن أحمد سعيد خضر, ʿAbd ar-Raḥman Ḫaḍr; born 1982) is a Canadian citizen who was held as an enemy combatant in extrajudicial detention in the United States Guantanamo Bay detainment camps, in Cuba, after being detained in 2002 in Afghanistan under suspicion of connections to Al-Qaeda.

His younger brother Omar Khadr was captured by United States forces separately at the age of 15 in Afghanistan in 2002 during a firefight; he was held in Guantanamo for several years but transferred in September 2012 to Canadian custody.

In his youth, Abdurahman Khadr was known as the "problem child" in the family, frequently running away and getting in trouble, refusing to follow rules, drinking alcohol and smoking cigarettes.

[6] In 1997, a dispute between the brothers was mediated by the older Abu Laith al-Libi, who earned their confidence and respect telling them about the city of Dubai and imported Ferraris; he was later described as "really cool" by Abdurahman.

[8] Once, when the two horses fought, the young bin Laden pointed a gun at Khadr, yelling at him to stop the fight before his prized Arabian was killed.

But, the next day bin Laden told Abdurahman that it would not work, and he asked Saif al-Adel to take the 16-year-old to the bus station so he could catch up with his family en route back to Peshawar.

[9] On August 20, 1998, the Al Farouq training camp was bombed by American cruise missiles and Amr Hamed, a friend of Khadr's, was killed.

Khadr claims he lived for nine months in a CIA safe house near the American Embassy in Kabul, and worked abroad as an informant.

[11] The New York Times later reported that the CIA offered Khadr a contract in March 2003 and asked him to work as an infiltrator for American intelligence in Guantanamo, to be paid $5,000 and a monthly stipend of $3000.

[12] While in Cuba, Khadr worked to obtain information from his fellow inmates before spending five additional months at the Camp X-Ray prison, where he claims to have been given training as an undercover CIA operative.

He phoned his grandmother Fatmah el-Samnah while in Sarajevo and asked her to go to the Canadian media and tell them that he had been stranded and refused entry back into Canada.

[19] In July 2004, Khadr was denied a Canadian passport by Governor General Adrienne Clarkson, on the explicit advice of Foreign Affairs Minister Bill Graham, by invoking the royal prerogative.
