MEXICO CITY (AP) — The bodies of two miners have been pulled from a small coal mine in a northern Mexico border state, bringing to three the number confirmed dead in the flood and collapse of the shaft. Three miners remain missing, and search efforts continued. There had been complaints for years about unsafe conditions at mines in the area. The federal civil defense office said efforts to pump out the mine continued in the coal belt of the northern state of Coahuila. President Andrés Manuel López Obrador said a dam or holding pond had collapsed, causing the flood.
