OMAHA, Neb. (AP) — At least nine people have been hospitalized and others could be trapped after an explosion and partial building collapse at an Omaha animal feed processing plant.

Interim Omaha Fire Chief Bernie Kanger (KANG'-ur) said Monday that nine workers have been sent to hospitals. He says firefighters are searching the building for anyone who may have been trapped by the blast or the falling debris. He declined to comment on possible fatalities.

Family members who have gathered outside the International Nutrition plant say they've received cellphone calls from their loved ones inside who told them one or two people may be missing or trapped.

The fire and explosion were reported at 10 a.m. Plant officials declined to comment to The Associated Press.
