Chinese state media say 21 workers are trapped in a flooded mine in eastern China in the country’s fourth serious mining disaster in the last 10 days.
The official Xinhua News Agency said Monday that water flooded a pit in Weifang city in Shandong province late Sunday.
It says seven workers in the pit managed to escape but the fate of 21 others is not known.
Rescuers are still searching for 63 miners trapped from three other incidents, some for as long as nine days.
In Shandong, 28 coal miners are still trapped after an air compressor caught fire Wednesday.
In southern Guangxi, 12 workers have been stranded in a coal pit since July 2. In neighboring Guizhou province, 23 workers haven’t been seen since a colliery flood nine days ago.
