The trial of four men accused of murdering former Lebanese PM Rafik Hariri has begun at an unprecedented tribunal at The Hague.
The four—alleged associates of the Syria-backed militant Shia movement Hezbollah—have not been arrested and are being tried in absentia.
Hariri and 22 others were killed by a massive car bomb in Beirut in 2005.
The killings polarised Lebanon and led to the withdrawal of Syrian troops. Hezbollah denies any involvement.
It instead says the assassination was part of an Israeli and US conspiracy.
