A state prosecution witness testifying at the trial of five former Bosnian Serb fighters said defendant Dragomir Vasic was in Bratunac and Srebrenica for three days in July 1995, during the Srebrenica genocide.
The Ratko Mladic trial continues with testimony from defense witness Bosko Kelecevic, who denied that the Bosnian Serb Army persecuted non-Serbs in the Krajina region in 1992.
Tens of thousands of people mourned at a commemoration ceremony in Srebrenica for the victims of the July 1995 massacres, but some targeted their anger at the Serbian prime minister.
International and Bosnian courts have so far sentenced a total of 37 people to around 630 years in prison for genocide and other crimes against Bosniaks from Srebrenica 20 years ago.
Over 2,000 people attended a ceremony in Sarajevo to honour victims from Srebrenica whose remains will be laid to rest on Saturday, the 20th anniversary of the genocide.
The Bosnian state court acquitted former Bosnian Serb Army serviceman Aleksandar Cvetkovic of taking part in the genocide of Bosniaks from Srebrenica in July 1995.
Testifying for the prosecution at the Ratko Mladic trial, the Forensic Director of the International Commission on Missing Persons (ICMP) said the remains of 604 victims were found in two mass graves near Prijedor.
Judges at the Hague examined the second prosecution witness to testify about the mass grave found at the Tomasica mine near Prijedor at the trial of Ratko Mladic, in a closed hearing.
