As rescue workers comb through chunks of concrete and lumber searching for survivors, Indonesian officials say that 832 people were killed in a powerful earthquake and tsunami on the island of Sulawesi.
Two days after the 7.5 magnitude earthquake hit the island, the death toll has continuously risen and authorities say more bodies could still be recovered.
Indonesian Disaster Management Agency spokesman Sutopo Purwo Nugroho estimates that 2.4 million people were impacted by Friday's earthquake.
Nugroho said 71 foreigners were in the city of Palu at the time of the quake and most were safely evacuated to Jakarta. At least five foreigners, including three French nationals as well as a Malaysian and a South Korean national, are unaccounted for, he said.
As of Sunday, there were no reports of US citizens affected in the quake, the US Embassy in Jakarta told CNN.
Survivors walked through floodwater and piles of debris. A shopping mall turned into rubble and the large dome of a mosque collapsed in Palu, home of 350,000 people.
Families carried the few belongings they could retrieve in plastic bags and backpacks to outdoor shelters where thousands hope to receive aid.
Hundreds were badly injured and at least 17,000 people were left homeless, Nugroho said.
The lack of heavy equipment and personnel has slowed down rescue efforts in the coastal city of Palu, where workers were scrambling Sunday to rescue about 50 people trapped beneath the debris of a collapsed hotel.
Indonesia's President Joko Widodo arrived in Palu on Sunday to survey the affected areas.
"I am asking all of you to work day and night to complete every tasks related to the evacuation. Are you ready?" he asked the country's military.
'It could get much worse'
As Widodo visits Palu on Sunday, the scale of the earthquake's destruction is still unclear.
Electricity and communications have been cut off and roads that are severely damaged or blocked by landslides are making it difficult to assess the damage, Nugroho said.
Jan Gelfand, head of the International Red Cross in Indonesia, says help is also on the way for the fishing towns of Donggala and Mamuju, two areas feared to be heavily devastated.
"The Indonesian Red Cross is racing to help survivors but we don't know what they'll find there," Gelfand said.
"This is already a tragedy, but it could get much worse."
With Palu airport closed, relief workers have to make their way there by road. Sulawesi is one of the biggest islands in the world and the drive from the nearest airport is around 10-12 hours.
Families mourn hundreds killed
Hundreds of families are already mourning the loss of their loved ones, including an air traffic controller who's been hailed as a hero.
Anthonius Gunawan Agung, 21, died in the hospital after he jumped off the traffic control tower at the Palu airport when he thought the tower was collapsing.
He stayed behind to make sure a passenger airplane safely took off, according to AirNav Indonesia, the agency that oversees aircraft navigation.
The current and former mayor of Palu are also among the dead, according to the Indonesian Red Cross.
Authorities have said the number of victims is expected to rise as families identify their relatives among the bodies recovered.
A massive quake
The horrific scene began Friday when a series of tremors rocked Sulawesi and a 7.5 magnitude earthquake triggered a tsunami that sent waves of "about three meters high" to the beaches of Palu and Donggala, officials said.
An early tsunami warning had been issued by the Indonesian meteorological agency, but was later lifted after the agency ascertained that the water had receded.
The quakes come a month after a trio of earthquakes hit several islands in the South Pacific and Indonesia, including Lombok, which is still recovering from the effects of an August 5 earthquake that killed more than 430 people.
