A video of Serbian policemen shooting dead Muslim civilians has been shown at a trial in Belgrade of five men accused of participating in the Srebrenica massacre.
The men, who were members of a police unit called the Scorpions, deny filming themselves shooting Muslim civilians.
8,000 Muslim men and boys were killed after Srebrenica fell to Bosnian Serb forces at the end of the Bosnian war in 1995.
The Human Rights Activist, Natasha Kandich, who found the video and gave it to TV stations, said she did it to help raise awareness among Serbians of what was done in their name.
However, she said this trial alone may not satisfy peoples' desire for justice.
This is the first time that anyone has been tried on charges related to the Srebrenica massacre in a Serbian court.
