A foreign security agency warned German officials that a terror cell in Germany may strike at any time in the coming months and may target public transport. The warning was vague, not unlike the general warnings from the U.S. government about possible attacks against U.S. interests at home or abroad. Germany has, however, implemented new anti-terror laws and cracked down on an Islamic group it considers a terrorist threat, launching a sweeping search of more than 200 mosques, offices and apartments of the group, the Union of Islamic Associations and Communities. It is possible the threat is a response to the increased police action.
