On Tuesday morning, German police launched a series of anti-terror raids against targets in Berlin linked to a mosque visited by the Christmas market truck attacker, in a comprehensive bust in which 460 police officers were deployed. The mosque is home to a Muslim association known as Fussilet 33, which was banned by Berlin's interior ministry on Tuesday.
Fussilet 33 has been closely watched by investigators for some time now, a police spokesman told television channel N24. It is suspected of radicalizing members and encouraging them to become jihadists for Islamic State, as well as collecting money for terror attacks in Syria.
Authorities targeted 24 locations in the raid. Among them were apartments, two business addresses and six holding cells in city jails in Berlin's Tegel and Moabit neighborhoods.
The Christmas market attacker is alleged to have visited the mosque frequently, before driving a truck into a crowd at Breitscheidplatz public square on December 19. A motion to ban the mosque was submitted on February 15, and one week ago, the association announced the closure of its prayer rooms with a notice on the door.
Special forces arrested three men a few weeks ago, who were suspected of attempting to travel to Syria and Iraq to receive training by Islamic State in weapons and explosives, and had allegedly been in contact with the mosque. No arrests in Tuesday's raid have been reported thus far.
