STL = Special Tribunal for Lebanon
"Its primary mandate is to hold trials for the people accused of carrying out the attack of 14 February 2005 which killed 23 people, including the former prime minister of Lebanon, Rafiq Hariri, and injured many others.
The tribunal was established following a request by the government of Lebanon to the United Nations. The agreement between Lebanon and the UN was not ratified, and the UN brought its provisions into force through UN Security Council Resolution 1757." [STL's website viewed 15 July 2013]
