The Prosecution's appeal in the case of Zdravko Mihaljevic is discussed by Appellate Chamber members.
A Prosecution witness speaks about the arming of civilians and plans to establishment "a Serbian state."
The Prosecution has asked that the former prime minister of Republika Srpska be held in custody for another month, and the Court accepted proposal.
Evidence of firearm shots were found on bodies buried in a mass grave in Tulice, the Court has heard.
In 1993, civilians were massacred in the village of Tulice near Kiseljak. The Prosecution charges Zdravko Mihaljevic, also known as Pijuk, with this crime.
