It happened in March, 2008, in Kenya. The post-election period has generated the ignition of an old ethnic conflict between warriors tribes Maasai and Kalenjin.
Hundreds of people, armed only with bows and arrows, have confronted on the heights surrounding Olmelil Valley. Over 20 people lost their lives, including one man who was shot in the face with an arrow. It seems that, after all, people do not depend on military technology to kill themselves in bloody confrontations.
