The assassination of former Lebanese Prime Minister Rafik Hariri will be properly investigated after the UN Security Council approved Wednesday the installment of a tribunal.

Only ten of the fifteen member nations voted, as Russia, China, South Africa, Indonesia and Qatar decided to abstain.

The five countries previously said that UN’s implication contravenes the international laws and would create flurry in the region, where the situation is already tense due to fighting between Lebanese forces and Fatah al-Islam militants in northern Lebanon and political feuds.

The internal feud between the Lebanese government and opposition parties has delayed the establishment of the tribunal. Fouad Seniora, the Prime Minister of Lebanon has been asked several times by the Hezbollah-led parties to step down along with his government.

Rafik Hariri was a business tycoon and the Prime Minister of Lebanon in two rows. He was killed by suicide bomber in Beirut on 14 February, when his motorcade was passing the St. George Hotel. Along with Hariri 22 civilians were killed.

The investigation of his assassination is still being conducted and is supervised by a UN team lead by Serge Brammertz. Speculations emerged that Syria was involved in the assassination, but the authorities from Damascus denied such allegations.
