Rescue crews have recovered a seventh body from a coal mine in northern Mexico where an explosion occurred, according to AP. And a landslide at an opal mine in western Mexico has killed three people. Labor Secretary Javier Zolano announced the recovery of the seventh body at the coal mine in a Twitter message Friday. Seven other miners remain missing at the mine in the town of San Juan Sabinas, where an explosion Tuesday also injured a teenage miner, who lost an arm. The Economy Department said in a statement Friday that a landslide killed three men at the open-air Pata de Gallo opal mine in Hostotipaquillo in Jalisco state. The statement said the men were apparently scavengers looking for materials.
