A masked man spray-painted swastikas on parked cars in the center of the northern town of Safed on Monday afternoon as shocked schoolchildren looked on.

Pupils in an ultra-Orthodox elementary school saw the man and notified their teacher, Maariv reported. A school administrator alerted the police, who began a search for the suspect.

The identity of the man and his motive were not immediately clear.

In late December vandals scrawled anti-Jewish graffiti and swastikas in the southern city of Beersheba. No suspects were apprehended.

The swastikas and the daubed slogan, which read “Death to the Jews,” were found on a wall in Beersheba’s Heh neighborhood.

In April, Nazi slogans and swastikas were spray-painted in the Tel Aviv suburb of Bat Yam on the wall of a synagogue and at a nearby school.

The previous month, a similar incident took place in Jaffa, where anti-Semitic slogans and symbols were spray-painted on a number of houses and stores.
