Guantanamo's last UK inmate Shaker Aamer speaks from cell 19 November 2013 Last updated at 10:25 The last British resident being held in Guantanamo Bay has been broadcast speaking from his prison cell for the first time. Shaker Aamer, who has been in the military prison since 2002, spoke to US news channel CBS by shouting from his cell, calling for the world to hear the truth. His lawyer said he was being held even though he had been cleared for release. The Foreign Office said Mr Aamer's case "remains a high priority." As part of a recording made by the CBS 60 Minutes programme, Mr Aamer said: "Tell the world the truth... please, we are tired. Either you leave us to die in peace - or either tell the world the truth. Open up the place. Let the world come and visit. Let the world hear what's happening. Please colonel, act with us like a human being, not like slaves. He added: "You cannot walk even half a metre without being chained. Is that a human being? That's the treatment of an animal... It is very sad what is happening in this place. Nothing to hide The Saudi national, who has been held for 11 years and is one of 164 inmates, has not been charged with any offence and has been cleared for release from the prison in Cuba. He has permission to live in the UK indefinitely because his wife is a British national. They have four children and live in London. Mr Aamer's case was raised by Prime Minister David Cameron in talks with US President Barack Obama at the G8 summit in June. Clive Stafford-Smith, his lawyer and director of the justice charity Reprieve, told CBS that Mr Aamer had agreed to whatever conditions the British government wanted to place under him if he was released, "because he has nothing to hide." Asked why Mr Aamer was still being held despite having been cleared to leave, he said: "I think it is a fascinating question and I would love a little more transparency. I wish someone official would give me an explanation and they won't. No one will say why they won't let him go. In a statement, Mr Stafford-Smith said: "CBS's show gives a very rare and very shocking glimpse inside Guantanamo Bay. Everyone in the prison - the guards and the men - is suffering horribly, day after day. [Mr] Obama must fulfil his promise to close the prison and Shaker Aamer must come home to his family in the UK, which is what David Cameron has said he wants. Matter of urgency Mr Aamer was detained in Kabul, Afghanistan in 2001. US authorities allege he had led a unit of Taliban fighters against Nato troops and had met the former leader of al-Qaeda, Osama Bin Laden. But Mr Aamer has always said he was in Afghanistan with his family to do charity work. A spokesman for the Foreign Office said: "Mr Aamer's case remains a high priority for the UK government and we continue to make clear to the US that we want him released and returned to the UK as a matter of urgency." The spokesman said the case had been raised with the US president by Mr Cameron and with Vice-President Joe Biden by Deputy Prime Minister Nick Clegg. We are confident that the US government understands the seriousness of the UK's request for Mr Aamer's release. Any decision regarding Mr Aamer's release ultimately remains in the hands of the United States government. We continue to monitor Mr Aamer's welfare through engagement with the US authorities. At least 14 British nationals and residents have been held at Guantanamo Bay at one time, with Binyam Mohamed's release in 2009 leaving only Mr Aamer there.
