At a carnival procession in Spain, participants dressed like Nazis and Jewish concentration camp prisoners while dancing next to a float evoking crematoria.

The Israeli Embassy in Madrid on Tuesday protested the display this weekend at the annual carnival procession in Campo de Criptana, a town situated about 80 miles southeast of the capital.

“We condemn the vile and repugnant representation that disrespects the victims of the Holocaust,” the embassy wrote on Twitter, “making fun of the murder of millions of Jews by the Nazis. European nations must collectively fight anti-Semitism.”

A video of the procession shows the participants marching in their fake Nazi uniforms. Behind them, dancers wearing striped outfits evoking concentration camp uniforms followed while waving flags of Israel. They were followed by the float shaped like a train locomotive with two large chimneys.
