LONDON (AP) — A lawyer says newly freed Guantanamo Bay prisoner Shaker Aamer wants an independent inquiry to examine whether British officials played a role in his treatment.

Human rights lawyer Clive Stafford-Smith told BBC on Saturday that Aamer wants "the whole world" to know what happened to him so rules can be enacted to keep others from facing torture. His lawyers say he was tortured and kept in isolation for extended periods.

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

He is being treated in a British hospital and reuniting with his family.

Aamer, 48, is a citizen of Saudi Arabia but a resident of Britain. British officials had lobbied for his release.
