 Hariri tribunal set to open 
 

It has been more than four years since Rafiq al-Hariri, the former prime minister of Lebanon, was assassinated.

The truck bomb that killed al-Hariri also left 22 others dead.

Now, after a lengthy UN investigation, the international tribunal that will eventually prosecute the case is set to begin its work at the Hague.

From Beirut, Nayla Khoury has more.
