Mine blast: Desperate relatives threaten pit rush

Rescue workers chipped away at walls of debris separating them from 65 Mexican coal miners today, as family members desperate for word on their trapped relatives threatened to rush past soldiers guarding the pit.

Almost three days after a gas explosion filled tunnels with fallen rock, wood and metal, rescuers have found no sign of the workers – either dead or alive - in the Pasta de Conchos mine, about 85 miles south west of Eagle Pass, Texas.
