BERLIN – Three people attacked a 26-year-old Jewish man in Berlin early on Sunday morning, lightly wounding him.The three men insulted and hit the man in front of a disco in the Mitte district, a neighborhood with many clubs and bars. He was wearing a T-shirt with a pro-Israel emblem on it, and the assailants learned that he was Jewish in the course of a conversation.Last August, a rabbi, 53, and his six-year-old daughter were attacked on a street in Berlin, apparently by four German Arabs. They broke his jaw and threatened to kill the girl.The police have not made arrests in either attack.
