Another three indictees -- Franc Kos, Stanko Kojic and Zoran Geronja -- pleaded not guilty, the Court reported.
Kos was the commander of the 10th commando unit of the Serb army when Srebrenica fell into the hands of Bosnian Serbs in July 1995, and Kojic, Geronja and Golijanin used to be members of that unit.
The state prosecutors indict all the four men for their involvement in the execution of some 800 people who were captured after the fall of the Srebrenica enclave.
Kos, who is a Slovenian citizen and Kojic, Golijanin and Geronja, who are Bosnian citizens, are being kept in detention in Sarajevo.
