Kosovo police have arrested five Serbian nationals, including four former police officers, on suspicion of committing a war crime during the 1999 conflict. The arrests, confirmed by a judicial source to French news agency AFP, mark the first in a recent series of investigations into alleged wartime offenses. Details regarding the specific nature of the alleged crime have not been publicly released. The arrests come amidst ongoing tensions between Kosovo and Serbia, particularly concerning the status of the Serb minority in Kosovo. Authorities have not disclosed when the suspects will appear in court. These developments are likely to further strain relations between Pristina and Belgrade. The investigation is ongoing, and further arrests are possible.
