Serbia expels a Croatian diplomat and further strains relations between the Balkan neighbors

[Collection]Serbia has expelled a Croatian diplomat, accusing him of "gross stepping outside the framework of diplomatic norms" and engaging in "spying activities" and "recruiting" for Croatian secret services. The move further strains relations between the two Balkan rivals. The Croatian foreign ministry rejected the reasons for the expulsion and warned of a deterioration in mutual relations. Tensions between the two countries have been ongoing since the Balkan wars in the 1990s.
