Moroccan nationalists protested the opening of an exhibition on Moroccan Jews in Tangier, displaying flags equating the Star of David with a swastika.

Some of the protesters posed for photographers while trampling the symbol, as well as Israeli flags.

At least 150 people gathered Feb. 18 in front of the venue where the Spanish government’s Cervantes Institute opened an exhibition entitled “The Spanish Jews in Morocco and their Diasporas,” the Spanish news agency EFE reported.

The protest in the northern Moroccan city was organized by the Coordination Committee for Political Forces for Palestine. Protesters chanted insults aimed at Andre Azoulay, a well-known Moroccan Jew and adviser to King Mohammed VI, according to EFE.

Signs denounced the exhibition as normalization of ties between Morocco and Israel.

Cecilia Fernandez Suzor, the director of the Cervantes Institute, a cultural center, told EFE that the same exhibition opened recently in Tetuan without incident, but that hardliners had organized an online campaign ahead of the opening in Tangier.
