German news magazine Der Spiegel says authorities are investigating reports that a German-born Islamic extremist arrested in Afghanistan has warned of possible terrorist attacks in Germany and elsewhere in Europe.
The man, identified as Ahmad S, reportedly has ties to the Taiba mosque in Hamburg where the perpetrators of the September 11 attacks met. German authorities closed the mosque last month. The Spiegel report says Ahmad S made the statement under interrogation by the US military at Bagram military prison.
