According to news reports, the village of Balaroa, virtually disappeared into a sinkhole due to the earthquake and around 70 per cent of the population lost their lives.

Latest figures from the UN humanitarian affairs office (OCHA) say that around 2,000 died overall in the disaster, with 11,000 injured and 680 still officially missing.

The UN chief, talking to reporters in Palu, said it was “the moment to express – and I want to do it on behalf of the UN and, I believe, the whole international community – full solidarity with the people of Sulawesi and the people of Indonesia, and an enormous admiration for the resilience that was demonstrated by the population impacted by this earthquake.”

“Their courage, their spirit of solidarity is remarkable” he added, saying that the response led by the Indonesian government had been “very rapid and effective”.

 “As the UN, we are ready to support the government; we already have people on the ground. But the leadership must always be the leadership of the government of the country and the international community needs to be supportive of that effort.”

Among the locals he met, were those recuperating at a Palu hospital, which had been partly destroyed in the disaster. He talked to some of the displaced who had either lost their homes, or were now too afraid to return. He also met families who had lost loved ones, as well as schoolchildren and their teacher, in a camp in Jalan Balaikota.

In several tweets from Palu, the UN chief had this message for locals across the devastated city and surrounding area: "To the many people I saw and spoke to - your strength and resilience are remarkable. The UN is with you."

"I was deeply saddened to see so many people suffering in Palu amidst so much destruction," he wrote.

Mr. Guterres travelled to the region with the Indonesian Vice-President Jusuf Kalla, and also met the Head of the Indonesian Disaster Management Authority, and governor of Central Sulawesi.
