A Canadian citizen was charged yesterday with helping arrange terror training for a group of men accused of plotting a suicide bomb attack in New York’s subways.

Ferid Ahmed Imam was charged simultaneously by federal prosecutors in Brooklyn and the Royal Canadian Mounted Police with joining in the plan to detonate explosive devices aboard subway trains.

Imam was also charged with arranging insurgency training at a Pakistan al Qaeda camp in a separate plan to attack NATO forces in Afghanistan.

The subway-bombing plot fell apart after authorities uncovered it in September 2009.
