The aircraft carrying Shaker Aamer, the last British resident to be held at the U.S. prison camp in the Guantanamo Bay navy station in Cuba, lands at Biggin Hill airport near London, October 30, 2015. Aamer has been freed after 13 years in detention, Britain said on Friday. Aamer, a Saudi national who is married to a Briton, was never charged with any crime and had been cleared for release by U.S. authorities in 2007 but was not freed. REUTERS/Peter Nicholls
