Rescuers in Indonesia are still trying to reach remote areas in Sulawesi cut off by the earthquake and tsunami that devastated parts of the island and killed more than 1,400 people.
Efforts have largely been focused on the city of Palu, where most of the confirmed dead have been counted.
This has angered people elsewhere, who say they have not received help.
The UN has warned that large parts of what might be the "worst-affected" areas have not been reached.
"But the teams are pushing, they are doing what they can," UN humanitarian spokesperson Jen Laerke said late on Tuesday.
Landslides, downed communications networks and collapsed bridges are making it hard for aid workers and rescuers to reach remote areas. The entire disaster zone is home to 1.4 million people and at least 70,000 have gathered in evacuation sites across the island.
Fears remain that the death toll could grow significantly higher as new areas are reached.
What's the latest on the ground?
In Donggala regency, an area home to 300,000 people, one aid worker told Reuters news agency that "the government is missing".
"Everyone is desperate for food and water. There's no food, water or gasoline," she said. Police officers have been guarding shops from looters.
President Joko Widodo is currently on his second trip to disaster-hit areas, but he has come in for criticism from some villagers.
"The president is not hearing about the remote areas, only about the tsunami and about Palu," said Yahdi Basma, who is from an area south of Palu.
"There are hundreds of people still buried under the mud in my village. I lost many members of my family and neighbours. There is no aid whatsoever which is why we're leaving."
More than 500 bodies have already been buried in mass graves. At least 29 countries have offered humanitarian aid, though some of it has been declined as unsuitable.
Singapore, South Korea, the UK, India and Japan have all offered C-130 military transport planes to help deliver supplies and help with evacuations.
The government has said it most urgently needs air transport, tents, water treatment systems, field hospitals and medical supplies.
In a separate incident, a volcano began erupting on the same island, Sulawesi, on Wednesday.
