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 1200 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.

In Palu, rescuers are awaiting heavy machinery to search the ruins of a hotel and a shopping centre as aftershocks made it unsafe for them to go in.
