Radical Islamist preacher Abu Hamza al-Masri has pleaded not guilty to 11 terror-related charges. Hamza was in a United States court Tuesday after losing a long legal battle to avoid extradition from Britain.

He could face life in prison if convicted of the charges, which include involvement in the 1998 kidnapping of 16 foreign citizens in Yemen and conspiring to set up a terrorist training camp in the U.S.
