In Palu -- home to around 350,000 people -- partially covered bodies lay on the ground near the shore, the morning after tsunami waves 1.5 metres (five feet) high slammed into the city.
Hospitals were overwhelmed by the influx of injured, with many people being treated in the open air, while other survivors helped to retrieve the remains of those who died.
The tsunami was triggered by a strong quake that brought down buildings and sent locals fleeing for higher ground as a churning wall of water crashed into Palu, where there were widespread power blackouts.
