Meanwhile, rescue workers are still trying to reach areas of Sulawesi in Indonesia affected by an earthquake and tsunami, UN humanitarians said on Monday, noting that more than 840 people have died and more than 600 have been severely injured in the disaster.

The update from the UN Office for the Coordination of Humanitarian Affairs (OCHA) follows the 7.4 magnitude tremor which struck Central Sulawesi at 5.02pm local time last Friday.

The quake subsequently caused a tsunami that hit coastal areas in Palu City and Donggala which has left more than 48,000 people sheltering in some 200 displacement sites.
