The defence for the four men indicted over the Omarska and Keraterm camps in north-west Bosnia has denied they took part in the crimes committed there in 1992.
The examination of the first witness for Dusko Knezevic's Defence at the trial for crimes in Omarska and Keraterm detention camps continues with no public presence.
Zeljko Mejakic's Defence claims he was not a camp commander, and that detention camps in Prijedor were established because of "what was happening in the field".
In less than a year, the Prosecution of BiH has examined 45 witnesses and presented 201 pieces of material evidence against the four indictees charged with crimes committed in Omarska and Keraterm detention camps.
