Russian diamond giant Alrosa says nine workers remained missing on August 4 after 133 others were evacuated from a flooded diamond mine in eastern Siberia.
Russia's Emergency Situations Ministry initially said that 151 workers were in the mine when water broke through and flooded the lower level of the mine.
But according to Alrosa, only 142 of 151 miners who were on shift at the time of the flooding were underground.
