Police in Berlin are investigating an assault on two young men, which was caught on film and shows the attacker shouting anti-Semitic abuse. The men, both wearing Jewish skullcaps (kippahs), were assaulted on Monday in the Prenzlauer Berg area. The video, later shared on Facebook, shows the attacker hitting the men with his belt and shouting "Yahudi," an Arabic word for Jew, before being dragged away by another man.
