Scaffolding at a construction site in eastern China collapsed, killing at least 74 workers.
Chinese state media reported it was the country's worst work-safety accident in more than two years.
The accident happened around 7:30 a.m. local time on Thursday when "the platform of a power plant's cooling tower under construction collapsed in Fengcheng, east China's Jiangxi Province," Xinhua News said.
The Associated Press reported:
"About 500 rescue workers, including paramilitary police officers, were digging through the debris with their hands, according to state broadcaster CCTV. It showed debris strewn across the floor of the cavernous, 545-foot-high concrete cooling tower, in the middle of which stood an unfinished structure.
"Rescue dogs were seeking to locate survivors or the bodies of victims, while backhoes shifted wreckage to the margins of the massive round tower."
State media said that President Xi Jinping "urged local authorities to step up efforts of rescue, treatment and follow-up work."
The scaffolding collapse is the latest in a series of deadly accidents in China that have been blamed on hasty construction and lax safety standards.
