A large blast hit the Lebanese capital, Beirut, ahead of the verdict in a trial for the killing of ex-pm Rafik Hariri in 2005.
Hundreds of people have died in the explosion while many are still missing.
Reports say the explosion was in the port area of the city, with unconfirmed reports of a second blast. A UN tribunal is due to issue its verdict in the trial in absentia of four suspects in the murder by car bomb of the late Hariri.
All four are members of the Iranian-backed Hezbollah group.
