Antisemitic graffiti has been sprayed across a bagel shop in the old Jewish quarter of Paris, prompting a police investigation.

Officers in the French capital said the word “Juden” – German for Jews – was discovered yesterday as anti-government “yellow vest” protesters and police forces clashed in other parts of the city.

The French League Against Racism and Anti-Semitism showed a photograph of the shop graffiti alongside a photo of a Berlin shop that was marked in a similar way in 1938 Nazi Germany.

The Representative Council of Jewish Institutions in France (CRIP), expressed “indignation and anger after the discovery of a revolting antisemitic tag on the window of a Bagelstein shop”.

The group says it was an “act that recalls the darkest hours of history”.

On the day the graffiti was found, vandals spraypainted more than 20 swastikas on sites across Bondi Beach in Sydney, Australia.

“The people of Bondi and indeed all Australians of goodwill will stand together in condemning this shocking display,” New South Wales’ Jewish Board of Deputies chief Vic Alha­deff told The Australian.

Officers in Bondi found around 20 of the symbols on a mural wall, as well as three more at a local shopping centre.
