London says aid to Hariri tribunal a testament of support for Lebanon LONDON, Dec. 10 (UPI) -- British Foreign Secretary William Hague said Tuesday a financial donation to the Special Tribunal for Lebanon is a testament of support for Beirut. Hague announced his government intends to make a voluntary contribution of $1.6 million to support the tribunal's work. "The U.K. is committed to supporting security, stability and justice for the people of Lebanon," he said in a statement. This contribution to the STL is a signal of our steadfast support for its work to end the climate of impunity for political assassinations in Lebanon. The tribunal is investigating the 2005 slaying of former Lebanese Prime Minister Rafik Hariri. Five suspected members of Hezbollah are implicated in the assassination. Hezbollah has said the assassination of Hariri was part of an Israeli plot meant to discredit the Shiite movement. The former prime minister was among 22 people killed in a bomb attack Feb. 14, 2005, in Beirut. Hague said he was sending Minister of State for the Middle East Hugh Robertson to Lebanon later this week to restate London's commitment to Beirut. Lebanon's national security is threatened by civil war raging in neighboring Syria. Hezbollah has been fighting alongside supporters of President Bashar Assad.
