Concepcion, Chile:
The death toll from the 8.8-magnitude quake in Chile now stands at around 800.
Emergency workers also say 19 people are still unaccounted for.
Chile's president has appealed for calm in the earthquake-ravaged city of Concepcion, vowing a stern response to any renewal of looting and violence.
Over 14,000 troops are now in the region, after dozens of people were arrested on Monday.
A BBC reporter in Concepcion says police are now posted on street corners in the city centre, but says that aid convoys are yet to reach the needy.
