People in Palu, Indonesia, are growing increasingly desperate for aid after a quake and tsunami hit the town.
Supplies of water, food and fuel are scarce and with roads damaged it is proving hard to bring more in, or reach the more remote areas.
The BBC’s Jonathan Head, who is in the town, saw police firing warning shots and tear gas at crowds trying to take items from a small shop.
At least 844 people are confirmed to have been killed by Friday’s disaster.
Officials say the final figure could be in the thousands.
Among those killed are 34 Indonesian students whose bodies were found under a church buried by a mudslide.
There are fears some survivors may still be trapped under the rubble of that and other buildings.
