Montenegro's police have arrested a Montenegrin suspected of killing at least six ethnic Albanians, including two women, in a Kosovo village in 1999.

The man arrested Thursday was identified as 47-year-old Vlado Zmajevic who had joined Serbian forces fighting Kosovo Albanian separatists seeking independence from Serbia.

Prosecutors say Zmajevic was arrested on suspicion of having committed "crimes against civilian population."

According to the Kosovo Humanitarian Law Center, Zmajevic was a key suspect in the crime committed in the Kosovo village of Zegra after Serbian paramilitaries arrived there in March 1999. At the time, NATO started bombarding Serbian troops to stop their brutal crackdown against the separatists.

Kosovo declared independence in 2008, something Serbia does not recognize.
