The last British resident held at Guantanamo Bay has denounced extremism in his first interview since being released in October.

Shaker Aamer told the Mail on Sunday that extremists "can get the hell out" if they are that angry with Britain. He sharply criticized recent attacks, such as the 2013 stabbing of a British soldier in London.

"How can you give yourself the right to be living here in this country, and living with the people and acting like you are a normal person, and then you just walk in the street and try to kill people?"

Aamer arrived in Britain in October after spending nearly 14 years as a prisoner at the U.S. facility in Cuba. He was never charged with a crime.
