Though he was never charged with any crime, al-Ajmi was held at Guantanamo through 2005. Military documents show he later claimed that his statements about fighting for the Taliban were made after he was threatened while in U.S. custody. He asserted that he was in Afghanistan to study the Quran.
Al-Ajmi was transferred to the custody of Kuwaiti authorities in November 2005, with four other Kuwaitis, and was released after a trial there, according to Pentagon officials.
Al-Ajmi is not the first former Guantanamo detainee to reportedly return to the battlefield after being released. Pentagon officials say there are more than 10 people once held by the U.S. at Guantanamo who have been killed or captured in fighting after being released from the detention facility. CNN
'Guantanamo man' in Iraq bombing
A former Kuwaiti detainee at the US camp at Guantanamo Bay carried out a recent suicide bombing in northern Iraq, the US military has said.
A spokesman for US Central Command told the Associated Press that Abdullah al-Ajmi took part in an attack in Mosul on 29 April that killed several people.
Ajmi and two other Kuwaitis blew up two explosive-packed vehicles next to Iraqi security forces, media reports say.
The US transferred Ajmi to Kuwaiti custody from Guantanamo Bay in 2005.
He was later acquitted by a Kuwaiti court of terrorism charges.
According to Kuwaiti and pan-Arab media reports, Ajmi and his two alleged accomplices, Nasir al-Dawsari and Badr al-Harbi, were able to leave Kuwait a month ago without alerting the attention of the authorities because they had wrongly been issued new passports.
They then travelled to Syria, where Ajmi is reported to have told his family of his intentions, before heading onto Iraq.
The families of Ajmi and Harbi reportedly later received anonymous calls informing them that the men had died in Iraq.
