Heilongjiang: Chinese authorities on Friday said that eight people remain trapped in a flooded iron mine in the country's northeast.
The accident comes a day after 10 people were killed when a building being refurbished in the financial hub of Shanghai collapsed.
Both incidents underscore continuing problems with occupational safety despite a government drive to improve standards.
The mine accident took place in Heilongjiang province's Cuihongshan at around 3 a.m. on Friday (1900 GMT on Thursday).
