Search for justice for Rafik Hariri

On the eve of the fourth anniversary of the murder that changed Lebanon's history, Saad Hariri, the young leader of the country's pro-Western Sunni parliamentary majority, received a phone call from Hillary Clinton.

The US secretary of state was ringing to assure him that the new American administration would do everything in its power to bring to justice those who killed his father, Lebanon's former Prime Minister Rafik Hariri.

Last week, seated next to his father's photograph in his spacious brand new mansion in the historic heart of Beirut, Rafik Hariri's political heir said he knew who was behind the killing.
