Bosnian police have arrested 13 Muslim citizens suspected of war crimes against ethnic Serbs in the south of the Balkan country during the 1992-1995 civil war.

In a statement, the prosecutor's office in the Konjic region said: "These are former officials of the Bosnian army, territorial defence (forces) and the interior ministry, suspected of war crimes committed against several dozen Serbs." 

The 13 are suspected of "murders, torture, rapes, persecutions and expulsions" of civilians, the statement said.

Police said they had arrested the suspects in Konjic and the capital Sarajevo.

Last month Edhem Zilic, a former member of Bosnian Muslim forces who served as an official at a detention camp for Serbs in Konjic during the war, was sentenced to nine years in prison by a Sarajevo court.

Bosnia's inter-ethnic war claimed 100,000 lives, while 2.2 million people were displaced.
