An Oregon man pleaded guilty on Friday to being an accessory after the fact for helping people linked to a suicide bomb attack on the headquarters of Pakistan's intelligence service in 2009 that killed about 30 people, court records showed. Reaz Qadir Khan, 51, a naturalized US citizen living in Portland, admitted in a plea entered in US District Court that he provided advice and financial aid to the suicide bomber's Maldives-based wives following the attack, knowing that such assistance would hinder and prevent their capture.
