Abid Naseer questioned Najibulla Zazi for about an hour. Naseer is acting as his own attorney at his trial in federal court in Brooklyn.
Assistant U.S. Attorney Celia Cohen told jurors in federal court in Brooklyn that the failed conspiracy in 2009 called for attacks in New York City, England and Denmark.
Prosecutors said Naseer was an al-Qaeda operative who collected bomb-making materials and scouted potential targets as part of Najibullah Zazi’s plot to carry out coordinated suicide bombing attacks.
Abid Naseer, 26, arrived at John F. Kennedy International Airport Thursday afternoon from England to stand trial in Brooklyn. He will be arraigned on Monday.
