A UK-based Pakistani terrorism suspect has been allowed to cross-examine a convicted terrorist at a US trial.
Abid Naseer, who is accused of being an al Qaida operative and is representing himself, questioned Najibulla Zazi at his trial in federal court in New York.
Prosecutors say both men were part of an al Qaida conspiracy in 2009 to stage attacks in Manchester, New York and Denmark. Zazi pleaded guilty in 2010 and agreed to cooperate as a government witness.
In his cross-examination, Mr Naseer sought to distance himself from Zazi by getting him to acknowledge the two had never met before.
Zazi also testified that he never heard his al Qaida handlers mention Mr Naseer's name.
Mr Naseer was extradited from Britain in 2013. If convicted, he faces a possible life sentence.
