Disturbing antisemitic graffiti was discovered on storefronts across a main Jewish neighborhood in Paris, France on Monday.

The vandals targeted multiple businesses in the 9th arrondissement, including spray painting Stars of David on shop doors.

“We denounce the many antisemitic tags found this morning on the facades of stores in the 9th arrondissement of Paris,” the Union of Jewish Students of France (UEJF) said on Twitter. “The whole neighborhood is covered with Stars of David, the word ‘Jude’ or even the expression ‘I am a racist’ tagged in large white letters.”

The UEJF noted that photos taken of the vandalism were “not archival photos of Kristallnacht but the streets of Paris on Monday.”

“Some want to transform the week of commemoration of the liberation of the death camps, which opens today, into a week of apology for Nazi antisemitic policies,” the UEJF said.

They called the vandalism a serious threat to the local Jewish community.
