In the past 24 hours, more evidence of former Guantanamo detainees rejoining their terrorist friends has resurfaced. Saudi Arabia released a list of 85 most wanted terrorists. The list includes 11 former Guantanamo detainees who were placed in Saudi Arabia's rehabilitation program, but the rehab did not take. According to the New York Times, the list also includes an al Qaeda terrorist who is operating a network of more than 100 Saudis on Iranian soil. This terrorist is reportedly the head of al Qaeda's operations inside the Gulf and responsible for attacks inside Saudi Arabia.
In related news, the British claim that a former Guantanamo inmate has gone to join the Taliban's high command:
"[UK Government officials] say Mullah Abdul Kayum Sakir, who was released last year, is now closely involved in planning attacks on British and other NATO forces in Afghanistan. They say he is operating with impunity from the Pakistani city of Quetta. â€¦ British government officials say Mullah Abdul Kayum Sakir was handed over by the Americans in the spring of 2008 to the Afghan authorities, who briefly imprisoned him in Kabul. But from there he was released and promptly made his way over the Pakistani border to rejoin the Taleban and its leadership. Since then, says a US counter-terrorism official, he has had a hand in doing some very bad things."
I have searched the U.S. government's unclassified files and not found any former detainees with a name similar to Mullah Abdul Kayum Sakir. It is possible that this Taliban member was known by another name while in custody and changed it upon release. It is also possible that the Brits got his identification wrong. I'll post more information on him should corroborating details emerge.
