Guardian report: the full story of the Guantanamo Britons:

"Three British prisoners released last week from Guantanamo Bay have revealed the full extent of British government involvement in the American detention camp condemned by law lords and the Court of Appeal as a 'legal black hole'.

After more than 200 interrogation sessions each, with the CIA, FBI, Defence Intelligence Agency, MI5 and MI6, America has been forced to admit its claims that the three were terrorists who supported al-Qaeda had no foundation.

But fearful of reprisals - the extreme right wing BNP has a stronghold in their hometown of Tipton in the West Midlands, and their families have warned them they may not be safe back at home - they all declined to be photographed, and are choosing a new location in which to rebuild their lives...

Among other disclosures, the three men revealed:

· How early in their ordeal they survived a massacre perpetrated by Afghanistan's Northern Alliance troops who herded hundreds of prisoners into lorry containers and locked them in, so that people started to suffocate. Iqbal described how only 20 of 300 prisoners in each container lived, and then only because someone made holes in its side with a machine gun - an action which killed yet more prisoners;

· The existence of a secret super-maximum security facility outside the main part of Guantanamo's Camp Delta known as Camp Echo, where prisoners are held in tiny cells in solitary confinement 24-hours a day, with a military police officer permanently stationed outside each cell door. The handful of inmates of Camp Echo include two of the four remaining British detainees, Moazzem Begg and Feroz Abbasi, and the Australian, David Hicks;

· That they endured three months of solitary confinement in Camp Delta's isolation block last summer after they were wrongly identified by the Americans as having been pictured in a video tape of a meeting in Afghanistan between Osama bin Laden and the leader of the 11 September hijackers Mohamed Atta. Ignoring their protests that they were in Britain at the time, the Americans interrogated them so relentlessly that eventually all three falsely confessed. They were finally saved - at least on this occasion - by MI5, which came up with documentary evidence to show they had not left the UK;

· That their first interrogations by British investigators - from both MI5 and the SAS - took place in December 2001 and January 2002 when they were still being held at a detention camp in Afghanistan. Guns were held to their heads during their questioning in Afghanistan by American soldiers, and physical abuse and beatings were rife. At this point, after weeks of near starvation as prisoners of the Northern Alliance, all three men were close to death."
