"We pay tribute to Croatian anti-Fascists who courageously stood up against Nazism and Fascism in Croatia and thus enabled Croatia to be among the victors at the end of the WW2," Plenković wrote on his Twitter account.
Anti-Fascist Struggle Day is observed in Croatia on 22 June as a bank holiday in memory of 22 June 1941 when the first Partisan detachment and the first anti-Fascist unit in this part of Europe were founded in Brezovica Forest near Sisak.
