In the wake of the 1994 the assassination of Juvenal Habyarimana, the Hutu president in Rwanda, triggered the bloodshed of massive proportions. When President Habyarimana's plane was shot down by ground missiles, Hutu extremists seized power in the country and began a slaughter of all Tutsis and moderate Hutus. In just 100 days mass killings perpetrated by millitia took a death toll of more then 800,000 people. Men, women, and children were murdered without regard. Since bullets were expensive, most of the killing was done with machetes or clubs in a brutal manner. A large number of victims were often tortured before being killed. Thousands of Tutsi women were raped and kept as sex slaves for weeks. The international community refused to intervene and stop the violence at first. When they finally decided to react, the aftermath of genocide found in the country was absolutely horrible. Read more on Rwanda genocide here. You can also watch a documentary on the horrible event.
