The 29-year-old was wearing a top with the Israel Defence Forces (IDF) logo when the attackers started harassing him yesterday about his religion, the police added, calling it “an anti-Semitic attack”.

Officers are seeking the assailants, who fled immediately after the attack, on suspicion of a politically-motivated crime.

Today is the second anniversary of an attack by a far-right gunman on a synagogue in the eastern German city of Halle, who killed two in a rampage when he failed to break into the house of worship.

It was one of a string of incidents that led authorities to declare the far right and neo-Nazis Germany’s top security threat.

Also this week, a musician claimed he was turned away from a hotel in eastern city Leipzig for wearing a Star-of-David pendant.

While the allegations prompted a fierce response from a Jewish community unsettled by increasing anti-Semitic crimes, several investigations have been mounted into contradictory accounts of the incident.

In 2019, police recorded 2,032 anti-Semitic crimes, an increase of 13% year-on-year.

“The threat is complex and comes from different directions” from jihadists to the far right, the federal government’s commissioner for the fight against anti-Semitism Felix Klein said recently.
