Amri caught on camera in a radical mosque just after the attack

German police officers on a regular stakeout at a radical mosque in the Moabit district of Berlin caught Anis Amri on camera a few hours after the truck attack killed 12 people at a Christmas market. He was not detained because he was not a suspect at the time. By the time the police raided the mosque on Thursday morning, he was gone.

Early Friday, German special forces arrested two brothers from Kosovo, aged 28 and 31, suspected of planning an attack on a shopping mall in Oberhausen in the western state of North Rhine-Westphalia. They were detailed on information from security sources.
