The United Nations special tribunal investigating the murder of former Lebanese Prime Minister Rafik al-Hariri has reached surprising new conclusions -- and it is keeping them secret. According to information obtained by SPIEGEL, investigators now believe Hezbollah was behind the Hariri murder.

It was an act of virtually Shakespearean dimensions, a family tragedy involving murder and suicide, contrived and real tears -- and a good deal of big-time politics.

On February 14, 2005, Valentine's Day, at 12:56 p.m., a massive bomb exploded in front of the Hotel St. Georges in Beirut, just as the motorcade of former Prime Minister Rafik al-Hariri passed by. The explosives ripped a crater two meters deep into the street, and the blast destroyed the local branch of Britain's HSBC Bank. Body parts were hurled as far as the roofs of surrounding buildings. Twenty-three people died in the explosion and ensuing inferno, including Hariri, his bodyguards and passersby.

The shock waves quickly spread across the Middle East. Why did Hariri have to die? Who carried out the attack and who was behind it? What did they hope to achieve politically?

The Hariri assassination has been the source of wild speculation ever since. Was it the work of terrorist organization al-Qaida, angered by Hariri's close ties to the Saudi royal family? Or of the Israelis, as part of their constant efforts to weaken neighboring Lebanon? Or the Iranians, who hated secularist Hariri?

At the time of the attack, it was known that Hariri, a billionaire construction magnate who was responsible for the reconstruction of the Lebanese capital after decades of civil war, wanted to reenter politics. It was also known that he had had a falling out with Syrian President Bashar Assad after demanding the withdrawal of Syrian occupation forces from his native Lebanon. As a result, the prime suspects in the murder were the powerful Syrian military and intelligence agency, as well as their Lebanese henchmen. The pressure on Damascus came at an opportune time for the US government. Then-President George W. Bush had placed Syria on his list of rogue states and wanted to isolate the regime internationally.
