They all face four counts of crimes against humanity and one of violations of the laws and customs of war in connection with mass expulsions and massacres allegedly committed by forces under their control between January and June 1999.
According to the indictment, as many as 800,000 Albanians were expelled from their homes during that period.
This week prosecutors brought to court Kosovo Albanians who spoke about crimes they had witnessed in the villages around the town of Djakovica.
They refuted the defense claims that the Albanians had fled Kosovo because of NATO air strikes, and that the Albanian men who were killed had mostly been members of the Kosovo Liberation Army, KLA.
They insisted that the Albanians were expelled by Serbs, not NATO, and that the villagers were further humiliated by being forced to cheer “Serbia, Serbia”, before being forced out.
The trial continues next week.
