STOCKHOLM (AP) — European security officials say a Norwegian man has received terrorist training from al-Qaida’s offshoot in Yemen and is awaiting orders to attack the West.

Western intelligence officials have long feared such a scenario: a convert to Islam trained in terrorist methods who can blend in easily in Europe and the United States and travel without visa restrictions.

Officials from three European security agencies confirmed Monday that the man is “operational,” meaning he has completed his training and is about to receive a target. All requested anonymity because they were not authorized to discuss the case.
