NZ mine rescuers between 'a rock and a hard place'

Twenty nine men are missing following an explosion in a coal mine in New Zealand.

Andrew Watson of the Mines Rescue Service said rescue efforts would be frustrated by fears for the safety of the rescuers themselves.

He said the trapped men would have been "trained to barricade themselves into somewhere where they are safe" and "hit solid strata" to let rescuers know they are alive.
