German police raid Berlin homes connected to market attacker

German investigators searched a refugee centre and a flat in Berlin on Tuesday which they believe were homes to associates of the Tunisian man who killed 12 people in an attack in the capital before Christmas, the federal prosecutor's office said. Anis Amri, 24, ploughed a truck through a Berlin Christmas market on Dec. 19. Islamic State claimed responsibility for the attack, calling the assailant a "soldier" of the militant group.
