LONDON (AFP) - A British legal charity is suing the British government over the rendition of terror suspects from Iraq to Afghanistan, it said Monday. Reprieve wants to force ministers to identify two men who were arrested by British forces in Iraq in 2004 before being handed over to the US and taken to Bagram air base in Afghanistan. This would allow Reprieve to try and secure a court hearing on their behalf to determine whether or not their detention is legal. The charity says it believes the two men may be Pakistanis named Salah el Din from Balochistan and Saifullah from Punjab, but this information is not enough to identify them fully or track down their families. Its solicitors, Leigh Day and Co, said in a letter to Defence Secretary Bob Ainsworth that the pair may well have been tortured or subjected to cruel, inhuman and degrading treatment. Britain admitted in February it had captured the pair in Iraq and handed them over to US agents, who transferred them to Afghanistan for interrogation. Then defence secretary John Hutton told the House of Commons the men were members of Lashkar-e-Taiba, a Pakistan-based group blamed by India for last years terror attacks on Mumbai which killed over 165 people. Imagine, if you will, that a criminal was to apologise for taking part in a kidnap, but then refuse to name his victims, or to help secure their freedom - we would hardly accept the apology as being sincere, Reprieves director Clive Stafford Smith said. He added there was an urgent moral, as well as legal, duty to repair the damage which he said had been caused. The Ministry of Defence said it was considering the case, adding: These individuals are in the custody of the US government. We have no reason to believe that Reprieves unsubstantiated allegations about their welfare are accurate. The US has assured us the detainees are held in a humane, safe and secure environment within the detention facility, which meets international standards for the care and custody of detained persons.
