Abu Hamza Al Masri is a co founder of the group Al Muhajiroun and Hizb ut Tahrir and a close associate of the AM leader Sheik Omar Bakri Mohammed.
Hook-handed Islamic extremist Abu Hamza has contracted gangrene in the stump of his left arm which could delay his extradition to the United States.
Hamza was due to face a four-day hearing at Woolwich Crown Court to decide whether he should be sent to the US to face terrorism charges.
His legal team fears he could be held with other al Qaeda suspects and possibly tortured at the notorious Guantanamo Bay detention centre.
On Monday he was taken from his cell at Belmarsh for an operation under general anaesthetic at a London hospital where surgeons removed one and a half inches of bone. (NEXT TIME FORGET THE GENERAL ANAESTHETIC)
