Fatalities reported in Nebraska animal-feed factory blast
A fire chief in Omaha, Nebraska, says an explosion and partial building collapse at an animal feed processing plant has claimed lives, the BBC reported.
Chief Bernie Kanger would not say how many had been killed, but told reporters emergency crews had ended rescue efforts in the unstable remains.
Ten workers inside the International Nutrition plant were taken to hospital, with four in critical condition.
The cause of the blast has not yet been determined.
But Mr Kanger said there were no hazardous chemicals in the building.
The fire that followed the explosion around 10:00 local time (16:00 GMT) has been extinguished, but firefighters were carefully searching the structure, wary of falling debris.
Thirty-eight people were inside the building at the time of the blast.
