Vehicles and a dumpster in the central Israeli town of Lod were found to have been spray-painted with swastikas on Thursday, police said, in the latest incident in a wave of both anti-Jewish and anti-Arab graffiti and vandalism that has swept the country in recent weeks.

Police said they were opening an investigation into the Lod incident. According to a law enforcement source cited by the Walla website, authorities believe that the swastikas may have been painted as a prank by a group of children, but gave no further details.

On Tuesday, the gravesite of a 2nd-century rabbi was vandalized in northern Israel with swastikas spray-painted onto its dome, police said, in an apparent reprisal for recent hate crimes against Muslim places of worship.

The words “Tag will pay a price” were found on the defaced grace of Rabbi Abba Halafta, seemingly in reference to the perpetrators of recent “price tag” attacks against Muslims in the north.

On Saturday a memorial garden for 16 soldiers at a high school in Beersheba was vandalized ahead of Israel’s Memorial Day. Police were investigating the incident.
