The United Nations International Independent Investigation Commission or UNIIIC was established on 7 April 2005 by Security Council Resolution 1595 to investigate the assassination of former Prime Minister of Lebanon, Rafic Hariri, who had been killed in Beirut on 14 February 2005.
A second, expanded, report followed on 10 December 2005. Five days later, on 15 December 2005, the Security Council voted unanimously to extend the investigation for another six months to 15 June 2006. That same day Detlev Mehlis stepped down as chief investigator to return to Berlin.
On 19 November 2007 Secretary-General Ban Ki-Moon appointed Canadian Daniel Bellemare to replace Brammertz on 1 January 2008 after he leaves to replace Carla Del Ponte as chief prosecutor at International Criminal Tribunal for the former Yugoslavia.
On 28 November 2007 Brammertz presented the Commission's ninth report.
In its various reports, UNIIIC determined that members of Lebanese and Syrian security and intelligence agencies committed the assassination through members of Hisbollah.
