They are the images that have finally, 10 years later, shocked a nation. A man, several men, are unloaded from a truck, marched to a wooded hillside and shot, one by one, in the back. Two prisoners are ordered to carry the bodies to a barn. They too are then executed.
The murder of thousands of Bosnian Muslims from Srebrenica in the summer of 1995 is well documented. But a video that emerged this week during the trial of the former Serbian president, Slobodan Milosevic, has provoked a bout of soul-searching in Serbia, parts of which are still in denial over the horrors of the Bosnian war.
The footage was the first such graphic material from the massacre in Srebrenica to be shown in the country, where more than half of the population refuses to believe it even took place, according to a poll last month.
Nicholas Wood, sadly, suggests in The New York Times that even videotaped evidence of mass killings broadcast on national television might not make that much of an impact on Serbian public opinion.
In Belgrade, many passers-by appeared skeptical about the possible impact of the tape on public opinion.
"What was shown on that tape was just a tiny bit of the crimes committed throughout the war," said Neohjsa Mrdjenovic, a 29-year-old musician. "The footage will not change anything because people knew what had been happening. Everyone knew about the siege of Sarajevo all along. Unfortunately people don't care about it. They only care how to feed their family."
Rodoljub Cosic, 25, said: "The footage might change some people's opinion about Srebrenica, but the majority knew what had happened there. People knew what had happened in Srebrenica more than any other place as it has been often raised in public."
