The KLA was helped by Nato airstrikes against Serb forces in 1999
An EU war crimes prosecutor says that some former leaders of the Kosovo Liberation Army (KLA) should face charges of crimes against humanity.
Clint Williamson has spent three years investigating allegations of atrocities in the late 1990s, when Kosovo Albanian guerrillas were fighting Serb forces.
He said elements in the KLA murdered ethnic Serbs and other minorities.
There was also evidence of human organ harvesting and trafficking on a very limited scale, he said.
