Swastikas were discovered on Thursday on the frontages and windows of a dozen kosher stores in Paris, the Union of Jewish Students in France (UEJF) announced.
“We see it as a new demonstration of anti-Semitic hatred,” the union said.
A police source said four nazi swastikas were traced with a black marker on two shops, on the wall of a Jewish school and on a nearby building of the Boulevard Voltaire, in Paris’s 11th district.
"I make a point of expressing my emotion and my indignation following the discovery of swastikas on frontages of the Voltaire boulevard", said the city’s mayor Bertrand Delanoe, in an official statement.
"Such acts, which recall the darkest hours of our history, should not remain unpunished. In the name of Paris, I repeat my determination to fight without a break against anti-semitism, and to defend the values of tolerance and of respect which found the identity of our City," he added.
