Rising water levels have forced the suspension of efforts to rescue 29 Chinese miners trapped for three days in a flooded iron ore pit, the official Xinhua news agency reported on Saturday. Rescue teams were pumping out water and dredging silt from the mine shaft when a sudden rise of the water level forced them to be evacuated. Officials at the pit, in the northern Chinese region of Inner Mongolia, believed the miners still had a chance of survival and were discussing a new strategy, Xinhua said without elaborating. Six other miners rescued from the pit on Thursday were in good condition in hospital, it added.
