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.
