This is reported by the Romanian Digi24, referencing Russian and Serbian publications.
Meanwhile, a statement from his deputy, Zoran Andrejc, was shared on the Serbian's Facebook page. In it, he stated that the death of Zivkovic has not been confirmed and urged people to refrain from spreading news about it.
According to journalists, Zivkovic fought against Ukraine since 2014. In 2017, he was deemed a threat to national security in Romania and was banned from entering for 15 years. Additionally, he was a commander in the Serbian paramilitary organization Cetniciki Pokret, known for its nationalist and chauvinistic views.
The Romanian Security Service established that Zivkovic visited Romania four times. In Constanta, he was detained while photographing military radars along the Black Sea coast and transmitting GPS coordinates of these radars. Intelligence agencies believe he was interested in the NATO military base "Mihail Kogelniceanu."
“All actions of the Serbian citizen in Romania had the nature of secret operations and specific methods characteristic of espionage activities. The special measures taken by the General Directorate of Counterintelligence of the Romanian Information Service prevented the leakage of classified information that could have impacted national security,” stated the SRI, adding that Zivkovic was unable to access any secret information.
The publication Tuzlanki writes that in 2018 he was arrested on suspicion of recruiting Serbs for wars abroad. Allegedly, he received funding for this from the budget of the self-proclaimed Russian entity in the Luhansk region.
Zivkovic's name also appears in documents from the Prosecutor General's Office of Ukraine, where he, along with five other Serbian citizens, is suspected of attacking Ukrainian military personnel in the Donetsk and Luhansk regions.
