Blast Traps Mexican Miners

A massive blast at a coal mine in northern Mexico killed three miners and left at least 14 men trapped underground. Rescuers are working through the night and Chilean experts are on the way to assist, CNN reports. Authorities warn that the blast was so powerful that they don't hold out much hope of finding the missing miners alive. The blast seriously injured a 15-year-old boy who had been working on a conveyor belt outside the mine. The teen, who had been illegally employed by the mine, had both arms amputated in a local hospital. (More Mexico stories.)
