Tensions rise as Kosovo and Serbia dispute arrest of police officers.

Serbia claims to have arrested three Kosovo police officials in Serbian territory, while Kosovo authorities claim they were kidnapped within Kosovo's territory. The border between Kosovo and Serbia was never determined by a demarcation agreement. Kosovo's Prime Minister suspects that the Serbian army kidnapped the officers as revenge for the arrest of a notorious criminal. The incident occurred amid calls for Kosovo to de-escalate the situation in the Serb-majority north, where local Serbs have been protesting against newly elected mayors since May 26.
