Croatian Jews said Monday they would boycott a commemoration ceremony for victims of the country's most notorious World War II death camp, accusing authorities of failing to respond to a revival of pro-Nazi ideology.

"Jewish municipalities in Croatia decided not to take part in the commemoration for the Jasenovac camp victims," the country's main Jewish association said in a statement, according to AFP.

Instead of attending the event planned for later this month, a separate commemoration "in line with the Jewish tradition" will be organised, it added. The association said "daily political events related to relativization and revitalization of the (WWII pro-Nazi) Ustasha regime" were among the reasons for the boycott.
