UN and genocide
The London Times has the story:
"The bodies were still warm when Lieutenant Ron Rutten found them: nine corpses in civilian clothes lying crumpled by a stream, each shot in the back at close range. It was July 12, 1995, and the UN-declared “safe area” of Srebrenica had fallen the previous day. The lush pastures of eastern Bosnia were about to become Europe’s bloodiest killing fields since 1945.
Refugees poured into the UN compound. But the Dutch peacekeepers (Dutchbat) were overwhelmed and the Serbs confiscated their weapons. “From the moment I found those bodies, it was obvious to me that the Bosnian Serbs planned to kill all the men,” Rutten said. He watched horrified as Dutch troops guided the men and boys onto the Serb buses."
The article goes on the detail how, warned of a planned massacre in Rwanda, Kofi Annan forbade UN commanders stopping it. His cable told them of a "need to avoid entering into a course of action that might lead to the use of force and unanticipated repercussions. "
