The war crimes trial of former Bosnian Serb army leader Ratko Mladic has resumed at the International Criminal Tribunal for the former Yugoslavia in The Hague, Netherlands.
The session was expected to include testimony from the prosecution's first witnesses.
Elvedin Pasic held back tears as he recalled the loss of his father in the town of Srebrenica.
Mladic is accused of genocide for his role in the siege of the Bosnian capital, Sarajevo, and for orchestrating the killing of 8,000 Muslim men and boys at Srebrenica in 1995.
He is also accused over the 44-month siege of the Bosnian capital, Sarajevo, that killed thousands of people.
Mladic, 70, has denied wrongdoing. If convicted, he could face life in prison.
The prosecution's first witness, Elvedin Pasic, is to tell the court how he survived the execution of 150 people by Bosnian Serb soldiers in 1992.
His testimony is expected to be followed by that of UN adviser David Harland, who will focus on the siege of Sarajevo between 1993 and 1995.
Mladic's trial has been halted since May 17, a day after it opened, when the judge suspended the proceedings because of irregularities by the prosecution.
Mladic was arrested in Serbia last year after some 16 years in hiding.
