Washington (Agencies): On the sixth anniversary of the assassination of former Lebanese Prime Minister Rafiq Hariri, US President Barack Obama has reaffirmed his strong support for the Special Tribunal formed by the United Nations to find the truth behind the high-profile murder.

"Ending the era of impunity for political assassinations is essential to realising the justice and stability that the Lebanese people deserve, and any attempt to interfere with the Tribunal's work or fuel tensions within Lebanon must not be tolerated," Obama said.

Noting that the cause for which Prime Minister Hariri and so many Lebanese patriots gave their lives must remain a guide, Obama said the US will never waver in its support for the sovereignty, integrity and independence of Lebanon.

The US remains committed to the full execution of UN Security Council Resolutions 1559, 1680, and 1701.

"At this critical moment, we call on all friends of Lebanon to stand with the people of Lebanon, who must be free to determine their own destiny. And those Lebanese who forge their future in a spirit of peace and reconciliation will continue to have a strong partner in the United States," said the US President.

The UN tribunal is expected to accuse Hezbollah members of involvement in the 2005 killing. Hezbollah may be in a position to block the tribunal after its favored candidate Najib Mikati was named Lebanon's new Prime Minister.

In another statement, Secretary of State Hillary Clinton revealed that the US and international community stand solidly behind the people of Lebanon as they observe this day of sorrow.

"The February 14, 2005 assassinations of former Lebanese Prime Minister Rafiq Hariri and 22 others with a car bomb in downtown Beirut changed Lebanon forever. The assassination reminded all Lebanese of the fragility of their pluralistic system," Clinton stated.

Clinton said for decades, the people of Lebanon have fought for their right to live free from fear of murder for political reasons.

"We call on the next Lebanese government to provide stability and promote justice for the people of Lebanon by honoring its obligations to the Tribunal. This is a decisive moment for Lebanon," she added.
