Croatian government has held a commemoration ceremony at the site of a notorious World War II death camp despite a boycott by the Jewish and Serb communities in protest over alleged inaction to curb the surge of neo-Nazi sentiment in the country.

Prime Minister Tihomir Oreskovic and other officials laid wreaths during the solemn event Friday at the Jasenovac camp site, near Zagreb.

Croatia's Jewish community held a separate Holocaust commemoration a week ago. They have complained that the new right-wing Croatian authorities were downplaying the crimes committed by Croatia's pro-Nazi regime during the war.

Tens of thousands of Jews, Serbs and Gypsies died in death camps run by the Nazi puppet state of Croatia during WWII. The Jasenovac camp is known as the Croatian Auschwitz.
