BRITISH soldiers and air personnel who helped to operate a secretive US detention facility in Baghdad that was at the centre of some of the most serious human-rights abuses to occur in Iraq after the invasion have, for the first time, spoken about abuses they witnessed there.

Members of two Royal Air Force squadrons and one Army Air Corps squadron were given guard and transport duties at the secret prison, the Guardian has established. Many of the detainees were brought to the facility by snatch squads formed from Special Air Service (SAS) and Special Boat Service (SBS) squadrons. The abuses the soldiers and airmen say they saw included: — Iraqi prisoners being held for prolonged periods in cells the size of large dog kennels.

— Prisoners being subjected to electric shocks.

— Prisoners being routinely hooded.

— Inmates being taken into a sound-proofed shipping container for interrogation, and emerging in a state of physical distress. Codenamed Task Force 121, the joint US-UK special forces unit was at first deployed to detain individuals thought to have information about Saddam Hussein’s weapons of mass destruction.

Once it was realised that Saddam’s regime had long since abandoned its WMD programme, TF 121 was tasked with tracking down people who might know where the deposed dictator and his loyalists would be, and then with catching Al Qaeda leaders who emerged in the country after the regime collapsed. Suspects were brought to the secret prison at Baghdad international airport, known as Camp Nama, for questioning by US military and civilian interrogators.

The methods used were so brutal that they drew condemnation not only from a US human-rights body but from a special investigator reporting to the Pentagon.

A British serviceman who served at Nama recalled: “I saw one man having his prosthetic leg being pulled off him, and being beaten about the head with it before he was thrown on to the truck.”

On the 10th anniversary of the invasion of Iraq, former members of TF121 and its successor unit TF6-26 have come forward to describe the abuses they witnessed, and to state that they complained about the mistreatment of detainees. It is unclear how many of their complaints were registered or passed up the chain of command.

A Ministry of Defence (MoD) spokesperson said a search of its records did not turn up “anything specific” about complaints from British personnel at Camp Nama, or anything that substantiated such complaints. Nevertheless, the emergence of evidence of British involvement in the running of such a notorious detention facility appears to raise fresh questions about ministerial approval of operations that resulted in serious human-rights abuses.

Geoff Hoon, defence minister at the time, insisted he had no knowledge of Camp Nama. When it was pointed out to him that the British military had provided transport services and a guard force, and had helped to detain Nama’s inmates, he replied: “I’ve never heard of the place.”
