A mosque in Hamburg which has become known for its connections to the September the 11th attacks has been closed down by the authorities.
Officials say the Taiba mosque and cultural association was closed down amid fears it was again being used as a meeting point for islamic radicals.
September the 11th ringleader Mohammed Atta studied in Hamburg and regularly attended the mosque. Two other attackers later joined him there.
No one was arrested in the operation, although officers searched the building and confiscated material, including several computers.
A 2009 inquiry found a group of 11 people from the mosque and its cultural association travelled to a radical training camp in Uzbekistan.
At least one subsequently joined a terrorist organisation in Central Asia.
