He is the first Guantanamo Bay inmate to be freed since US President Barack Obama came to power.But, as Binyam Mohamed returned to the United Kingdom, he accused the American government of torturing him, with British collusion. An Ethiopian citizen formerly with British resident status, Mohamed was held at Guantanamo for more than four years and was never put on trial. British Foreign Minister David Miliband said: “We very much welcome President Obama’s commitment to close Guantanamo Bay and I see today’s return of Binyam Mohamed as the first step towards that shared goal.” Initially detained by British police upon his arrival, Mohamed was later freed although his long-term future following his release from Guantanamo remains unclear. Human rights groups say 241 detainees remain at the controversial US prison camp in Cuba. President Obama, in one of his first official acts after taking power, ordered the prison be closed by the end of the year.
