The US State Department has not commented on his specific allegations, but says it does not transfer prisoners for the purposes of torture.
Mr Habib told the BBC's World Service that, after his "kidnap" in Pakistan in 2001, he was moved between Egypt, Pakistan, Afghanistan and Guantanamo Bay until his release at the beginning of 2005.
He says he does not know who was holding him, but "I saw Americans.. Australians.. Pakistanis.. and Egyptians."
He spoke of being tortured while in detention in Egypt.
"It is a place for torture. I was beaten, electric shock... no sleep, injections, brainwashed - unbelievable stuff," he said.
