An Israeli-German wearing a kippah was attacked in a Berlin metro station by four Arab-speakers.
The man had to pass the four as he exited the station, at which
point the men pushed him and insulted him in Arabic (a language he
understood). One of the men apparently spat on him as he left.
Israeli did not respond and after the incident called the police. But
the four men had disappeared by the time a patrol car showed up.
