Desperate search for survivors

A picture of large-scale destruction is emerging in and around the Indonesian city of Palu after an earthquake and tsunami struck on Friday.

At least 832 people are confirmed to have died but that figure is expected to rise sharply as more remote areas are reached.
 The authorities have said they will begin burying victims in mass graves, fearing disease could begin to spread. Dozens of people are thought to be trapped alive under the rubble.

Indonesian President Joko Widodo visited the region to urge a "day and night" effort to rescue survivors.
