The 2020 Zagreb shooting, commonly referred to as the St. Mark's Square attack (Croatian: Napad na Trgu svetog Marka), occurred on 12 October 2020 in Zagreb, Croatia, when 22-year-old Danijel Bezuk approached Banski dvori, which houses the office of the Prime Minister and serves as the meeting place of the government, on St. Mark's Square and started shooting at it with an assault rifle, wounding a police officer in the process.

He subsequently took out an automatic rifle (5.45×39mm AK-74[3]) and opened fire on the 33-year-old police officer, Oskar Fiuri, who was guarding the main entrance, wounding him with four rounds, after which he continued shooting on Banski dvori.

Police then swarmed St. Mark Square looking for the attacker, but soon received the report of shots heard in the nearby Jabukovac Street, which turned out to be Bezuk taking his own life.

[9] In the immediate aftermath of the shooting, President Zoran Milanović held a press conference in which he called the government to protect the central state institutions, saying that "they are not a tourist destination".

[14] On 16 October, Croatian daily newspaper Jutarnji list, referring to the source from the police, published the article saying that prior to the attack Bezuk searched the internet for texts and photographs of government office location, building interior and regular movements of the President and the Prime Minister.

[16] In September 2022, Jutarnji list wrote that Bezuk's final message before committing suicide was identical to paroles of radical Croatian right-wing group called Banovina Horosan[17] which advocates spread of Islam and installation of sharia law in Croatia.
