The Police Chief said the delegation, which planned to attend a commemoration at Jaseonovac, did not follow accepted international protocol.

"We were not formally informed of the arrival of these individuals into Croatia," said Milina. "Therefore, pursuant to the State Border Control Act, their entry into Croatia was denied. When entering another country on official business, the arrival must always be announced ahead of time. There exist clear rules of conduct," he concluded.

According to reports, the delegation of eleven officers and cadets from a Serbian Military Academy was supposedly travelling to Jasenovac to commemorate Serb victims at the Jasenovac concentration camp during the Second World War.

Meanwhile, Prime Minister Andrej Plenković was harsher in his condemnation of the incident at the border, which he called a provocation.

"This is about an unannounced and unregistered attempt to enter Croatia for an event near Jasenovac at which full Serbian military uniforms were to be worn. The planned event was not commemorative in nature, nor was it designed to pay respect to victims, but rather a planned provocation designed to incite an incident. This behaviour goes against international law. For us, as a country, it is unacceptable and we strongly condemn it," said the prime minister.
