Divers from the UN investigating team and Lebanese civil defence carry a chunk of debris, near the Saint Georges Hotel's bay in Beirut, for possible use as evidence in the February 14 explosion that killed former Lebanese Prime Minister Rafik Hariri.

The massive seaside explosion threw the wreckage of several cars into the Mediterranean.
