LONDON -- U.S. authorities say an alleged Al Qaeda operative arrested in Britain was part of an international conspiracy to attack targets in England, the United States and Norway.

Lawyer David Perry told a court that the U.S. government is seeking the extradition of 24-year-old Abid Naseer so that he can stand trial for his alleged role in the plot, which Perry says included a plan to attack a Manchester shopping center in tandem with targets abroad.

Authorities in the U.S. and Norway have previously linked the purported attack with plots to bomb the New York City subway and an unspecified target in Norway.

Naseer has previously denied the allegations. He spoke Wednesday only to confirm his name and date of birth.
