Serbian prosecutors have charged nine Serbian ex-paramilitaries with killing 43 ethnic Albanian civilians during the Kosovo conflict in 1999.
In a statement, the war crimes prosecutor in Belgrade said the nine shot their victims in the back multiple times and burned the corpses.
The accused, former members of the Jackals paramilitary group, were detained in March.
The killings took place in the western village of Cuska in May 1999.
Serbian troops were driven out of Kosovo in 1999 after a Nato bombing campaign aimed at halting the violent repression of the province's ethnic Albanians, who constituted 90% of its two million population.
Kosovo declared independence in 2008 - a move which Serbia has refused to recognise.
Serbia now wants to join the European Union, but must first prove to Brussels that it is serious about prosecuting for atrocities committed during the wars in Croatia, Bosnia and Kosovo during the 1990s.
