Scores of people are injured and an unknown number are dead after a huge explosion at a fertiliser plant near Waco in the US state of Texas.
Dozens of homes and buildings have been destroyed, and several are still on fire, after the West Fertilizer plant exploded at about 19:50 (00:50 GMT).
Some people are thought still to be trapped in buildings and a number of firefighters are reported missing.
Emergency services officials said ammonia may have caused the explosion.
It has been reported the company had 54,000lbs (20 tonnes) of anhydrous ammonia on site.
The plant is right on the edge of town, only a few hundred metres from houses, a school and nursing home.
Sgt William Swanton of the Waco police department said power to the town had been shut off to prevent further accidents.
He confirmed there were deaths, but could not give a figure.
Police have been conducting house-to-house searches to check for casualties.
