PALU, Indonesia (Reuters) - The toll from an earthquake and tsunami in Indonesia soared on Sunday to 832 confirmed dead, with authorities fearing it will only climb as rescuers struggle to reach outlying communities cut off from communications and help. Dozens of people were reported to be trapped in the rubble of two hotels and a mall in the city of Palu, which was hit by waves as high as six meters (20 feet) following the 7.5 magnitude earthquake on Friday.
