Joko Widodo urges workers to work 'day and night' to rescues Indonesians

President Joko Widodo arrived Sunday in Indonesia's quake and tsunami-devastated city of Palu, urging a non-stop recovery effort after the disaster killed more than 800 people.

"I'm asking my brothers to all be ready to work day and night and to finish everything related to the evacuation," Widodo -- decked out in military fatigues -- told troops deployed to Sulawesi island.

"Ready?" he asked.

"Ready!" they shouted in response.
