German authorities believe Anis Amri is still hiding in Berlin after CCTV images showed the prime suspect in a deadly truck attack outside a mosque in the German capital's Moabit district.
Tagesspiegel newspaper cited investigators as saying that Amri, a 24-year-old Tunisian who had been due for deportation from Germany, fled the scene of the truck attack with severe injuries to the face and was therefore unlikely to risk fleeing beyond the city.
Meanwhile, Berlin's public broadcaster RBB showed CCTV images of Amri in front of the Fussilet 33 mosque, which has been described by German intelligence agents as a hub for radical Islamists. The mosque was one of several locations raided by police on Thursday.
RBB also reported that Amri had been filmed outside the mosque by German police on December 14 and 15, casting doubt on reports from Thursday indicating he had fallen off the domestic intelligence agency's radar weeks before the attack.
German Interior Minister Thomas de Maiziere said Thursday that it was "highly probable" that Amri had carried out the attack, which saw a large truck laden with steel ploughed into a Berlin Christmas market late Monday, killing 12 people and injuring dozens.
De Maiziere confirmed that fingerprints found on the driver's door and elsewhere on the Polish-registered truck were those of Amri, and that other evidence in the vehicle also pointed to the Tunisian national.
In what seemed to be an unrelated incident, German police said they had arrested two Kosovo-born brothers aged 28 and 31 on suspicion of preparing to commit a terrorist attack at a shopping centre in the western German city of Oberhausen.
