Three rescue workers killed at Utah Mine

A disastrous cave-in killed three rescue workers and injured at least six others who were trying to tunnel through rubble to reach six trapped miners, authorities said. Mining officials were considering whether to suspend the rescue effort.

It was a shocking setback on Thursday, the 11th day of the effort to find miners who have been confined at least 1,500 feet (450 meters) below ground at the Crandall Canyon mine. It's unknown if the six are alive or dead.
