A gas explosion in a coal mine in northern Mexico killed three miners, injured one and left 11 others trapped deep underground.

Relatives of 65 coal miners trapped underground for almost two days after a gas explosion grew increasingly desperate and frustrated today, as rescue workers provided no real news of their loved ones.

Rescue workers were burrowing through debris clogging a Mexican coal mine early today, a desperate effort to free 65 miners who had been trapped for more than a day by a gas explosion.
