BERLIN (AP) — A Berlin court has convicted a 19-year-old Syrian of serious bodily harm and slander for attacking a man wearing a Jewish skullcap in the German capital in April.

The 21-year-old victim, an Arab Israeli who said he wore the Jewish kippa, or yarmulke, in a show of solidarity with his Jewish friends, filmed his attacker whipping him violently with a belt while shouting "Yahudi!" — Jew in Arabic.

Berlin's regional court on Monday sentenced the defendant, who wasn't named due to privacy rules, to four weeks of juvenile detention, which he has already served while awaiting trial.

The attack was widely condemned and stoked a debate about anti-Semitism in Germany.

The defendant, who came to Germany in 2015 as an asylum seeker, told the court he regretted the attack.
