This is in Kosovo where NATO "peacekeepers", called KFOR, from the US, Germany, Italy, Britain, France etc. are supposed to be keeping the peace. The Serbs still left are surrounded by hostile Albanians and need protection. However, the protection is very poor, and ethnic cleansing of the minority population and destruction of their churches have continued these last few years.
Prizren is a town in southern Kosovo, and the Germans control this sector, the US controls the eastern and southeastern part of Kosovo, and so on.
