Lebanon 101: Why Hezbollah hates the Hariri tribunal.
Who is investigating Hariri's assassination?
In December 2005, the Lebanese government requested that the United Nations conduct an international investigation to try those who were allegedly responsible for Hariri’s death. In response, the UN Special Tribunal for Lebanon was established. It includes both Lebanese and international judges, as well as an international prosecutor, and was formally established in June 2007. It officially opened in March 2009 and is based in The Hague.
