U.S. prosecutors say a suspect in an alleged al-Qaida plot against the New York City subways also was part of a terror campaign that would have targeted Britain and Norway.
Abid Naseer pleaded not guilty Monday in a New York federal court. He was extradited last week from Britain.
Prosecutors in Brooklyn aim to prove that Naseer collected bomb ingredients, conducted reconnaissance and was in frequent contact with other alleged al-Qaida operatives.
If convicted, he could face up to life in prison.
