There are no official casualty figures, but Dr. George Smith, the head of Texas Emergency Medical Services in West, said at least 60 were dead and some 170 injured, broadcaster KWTX reported.

West Mayor Tommy Muska told an earlier news conference it had been confirmed at least four or five rescuers and firefighters were missing.

Muska said a fire broke out at the fertilizer plant before the explosion, which devastated surrounding areas, destroying 10 homes and damaging 50 more. It also triggered a 2.1-magnitude earthquake.

Witnesses said an evacuation had already begun before the explosion due to the fire at the plant. The huge explosion sounded like a nuclear bomb and sent a mushroom cloud into the air.

Rescuers launched a door-to-door search overnight in the area near the explosion, looking for dead or injured.

Toxic gas is feared to have been released into the air and authorities are worried that a second fertilizer tank may explode.

The cause of the explosion and the earlier fire in the plant is under investigation.

West is a small city of 2,600 residents. Half of the town was evacuated after the explosion.

Many journalists rushing to the scene are awaiting an official briefing at a temperay media center about 5 miles from the plant, roads to which have been closed.
