A statement issued by Serbia's Ministry of Foreign Affairs (MFA) said this was done "due to current issues in relations with Ukraine" – while stressing that Serbia has taken "a series of concrete steps to (judicially) process Serbian citizens who took part in wars abroad, including in Ukraine," B92 said.

"Minister Dacic recalled that it is well known that Ukrainian mercenaries took part in the crimes committed by Croatia's forces against the Serb people in Croatia (during the 90s) – whom Ukraine, unlike Serbia, never condemned," the statement said.

It added that Serbia on several occasions, since the outbreak of the crisis in Ukraine, demonstrated its respect for Ukraine's territorial integrity – something that was proven during Belgrade's OSCE chairmanship.

The statement also said that Serbia "remains committed to building good relations with Ukraine, based on principles of mutual respect" – and would not allow itself to become "collateral damage of international relations that have nothing to do with Serbia."

Earlier on Wednesday, November 8, Ukraine's Ministry of Foreign Affairs announced that the country's foreign minister the day before met with the Ukrainian ambassador in Belgrade – summoned back to Kyiv on November 3 – and that they discussed "bilateral issues (....) and the problem of Serbian mercenaries who fight in Donbas as part of the Russian terrorist troops."

All this unfolds after an interview was published on November 1 with Ukraine's ambassador to Serbia, Oleksandr Aleksandrovych – when he accused Serbia of being "used by Russia to destroy Europe."

The Serbian Ministry of Foreign Affairs reacted on November 2 by warning Kyiv that it would be "forced to take steps" unless the diplomat abandoned his "inadmissible behavior."

This was then interpreted as "the last warning before expelling an ambassador."
