KIGALI, RWANDA - APRIL 05: Dressed in traditional gowns, women line up before marching to commemorate the genocide of 1994 at the Kicukiro College of Technology football pitch April 5, 2014 in Kigali, Rwanda. On April 11, 1994, Belgian paratroopersm, who were part of the UNAMIR mission, were ordered to leave the school grounds, abandoning the people to the national police and Interahamwe militia, who lead their victims to a garbage dump and slaughtered them. Rwanda is preparing to commemorate the 20th anniversary of the country's 1994 genocide, when more than 800,000 ethnic Tutsi and moderate Hutus were slaughtered over a 100 day period.

For anyone wanting to read more about the Rwandan genocide, I strongly recommend "Shake Hands with the Devil: The Failure of Humanity in Rwanda" by retired General Romeo Dallaire, who was the Commander of UNAMIR.
General Dallaire spent that horrible time desperately trying to save anyone he could with the limited resources he had on hand, while fighting the UN bureaucracy to try and get sufficient resources on the group to stop what was happening.
