The Memorial to the Murdered Jews of Europe was discovered vandalized on Tuesday morning, according to the Berlin Police and the German Holocaust Memorial’s caretaking organization.

A stele at the Berlin memorial was discovered covered in green graffiti containing “inflammatory content,” according to a Wednesday police statement. The graffiti was covered by the site’s security, and a cleaning service was commissioned.

The investigation was taken over by state security, and there are no suspects. The Foundation Memorial to the Murdered Jews of Europe told The Jerusalem Post on  Thursday that the agency was reviewing the incident as antisemitic and seditious damage.  

“The Foundation strongly condemns this act of insult,” the organization said on Thursday.

On April 26, in the Berlin-Pankow borough, several instances of antisemitic graffiti on apartment buildings were discovered, according to Berlin Police.

“Kill all Jews” was painted on one wall, according to a photograph published by Israel’s ambassador to Germany, Ron Prosor. According to Judische Allgemeine, Jewish community members also saw a graffiti swastika and the statement “Only a dead Jew is a good Jew.”

In March, a Syrian man was convicted of stabbing a Spanish tourist at the Berlin Holocaust memorial last February. According to JTA, at the time, the asylum seeker and aspiring terrorist organization member told arresting officers that he wanted to kill Jews.
