The commemorative events will be attended by President and Armed Forces Commander in Chief Zoran Milanović,
The operation was mounted after rebel Serbs set up a police station in Plitvice and the Croatian state leadership decided to restore constitutional order there.
Jović, 22, was killed and nine other police officers were wounded in that police operation after the Serb rebels occupied Plitvice Lakes National Park and blocked the D1 state road that connects the country's north and south. Jović was a member of the Lučko Anti-Terrorist Unit.
The operation was launched on the morning of 31 March 1991, Easter Sunday, and is also known as Bloody Easter.
According to police reports after the operation, 29 Serb extremists were arrested and 18 were charged with armed rebellion, including Goran Hadžić, a member of the main committee of the Serb Democratic Party, and Borivoje Savić, secretary of the executive committee of the party's Vukovar branch. Although the Croatian police regained control of the local police station, they had to withdraw later and the area remained under rebel control until August 1995 when Operation Storm crushed the Serb insurgency.
Jović has been posthumously promoted to the rank of major and decorated with high state medals.
