Ambulances are seen at the site of a coal mine flooding accident in Leiyang, central China's Hunan Province, Dec. 3, 2020. Dozens of rescue workers entered a flooded coal mine shaft in central China's Hunan Province Thursday to search for 13 trapped miners. The new-stage rescue came after four days of pumping water out of the flooded Yuanjiangshan coal mine in the city of Leiyang, creating space for the rescue workers to launch the underground rescue operation, according to the local rescue headquarters.
