Bomb plot suspect 'backed holy war against US'

A police officer assigned to work undercover after the September 11 attacks has surfaced as a surprise witness at the trial of a Pakistani immigrant accused of plotting to blow up a Manhattan tube station.

The officer – who gave evidence under his street name, Kamil Pasha, because he is still involved in investigations – said he heard Shahawar Matin Siraj rant against the US in the months following September 11 2001, and predicted terrorists would inflict more harm.
