Judge Quentin Purdy said 24-year-old Abid Naseer can be sent for to the U.S. to stand trial for his alleged role in a terror campaign that would have struck at targets in Britain, Norway and the U.S.
U.S. authorities say they aim to prove that Naseer collected bomb ingredients, conducted reconnaissance and was in frequent contact with other al Qaeda operatives as part of a foiled international plot to detonate explosives aboard the New York City subway and a suspected plot to bomb a busy shopping area in the northern England city of Manchester.
Naseer was one of 12 people arrested in a counterterrorism operation in April 2009, but all were subsequently released without charge. They were ordered to leave Britain, but Naseer escaped deportation to his native Pakistan after a judge ruled it was likely he would be mistreated if he were sent home.
Naseer was re-arrested in July 2010 at the request of U.S. authorities.
Naseer, who wore a brown shirt, stroked his beard as the judge read out the ruling Friday but otherwise showed no reaction. Asked whether he understood that he could appeal the judgment, he said: "Yes sir, thank you."
Naseer's defense had argued that he could be mistreated or tortured if sent to America, an argument rejected by the judge.
Naseer is charged with providing material support to a foreign terrorist organization, conspiring to provide such support and "conspiracy to use destructive force." He faces a possible life sentence in the United States if convicted.
