Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei says any ruling by the US-sponsored Special Tribunal for Lebanon (STL) is null and void.The US-backed STL is charged with investigating the assassination of Lebanon’s former Prime Minister Refiq Hariri in February 14, 2005.Hariri was killed along with over 20 other people in a massive bombing in the Lebanese capital, Beirut. Set up nearly two Â years later to investigate the incident, the US-backed STL is expected to announce its findings by the end of 2010. Earlier reports indicated that the court planned to issue an indictment against members of the Lebanese resistance movement of Hezbollah. Hezbollah has rejected the allegations, saying the plot was part of “a dangerous project that is targeting the resistance,” and being one-sided in line with Israeli interests. Major political figures and parties in Lebanon have also condemned the indictment, calling it a US-Israeli plot to sow discord in Lebanon.In an August public address, Hezbollah Secretary General Seyyed Hassan Nasrallah delivered detailed speeches pointing to Tel Aviv’s role in Hariri’s murder.The televised address featured video materials, captured by Israeli unmanned aerial vehicles, and recorded confessions by Israeli fifth columnists, substantiating that Tel Aviv had been behind the terror attack. Different Lebanese factions have also accused the US-sponsored STL of using false witnesses, who reportedly gave unreliable testimonies to the international probe into Hariri’s 2005 assassination.
