(NEW YORK POST) – Indonesian rescuers scrambled Monday to reach ravaged Sulawesi island as the death toll from last week’s 7.5-magnitude earthquake climbed to 844 – including 34 children at a Christian camp – and was expected to rise.

Dozens of people were believed to be trapped in the rubble of several hotels and a shopping center in the city of Palu on Sulawesi, about 930 miles from Jakarta, while hundreds more were feared buried in landslides that buried villages, Reuters reported.

Of particular concern is Donggala, a region of about 300,000 residents north of Palu that is close to the epicenter of the quake, which triggered a tsunami with waves as high as 20 feet.
