An explosion Monday morning that brought down part of an animal feed processing plant in Omaha left two people dead and 10 others seriously hurt, authorities said.

 The search for bodies in the crippled International Nutrition plant progressed slowly Monday, but the death toll wasn't likely to get bigger.

Omaha Police Lt. Darci Tierney said Monday evening that all 38 of the workers who were in the building at the time had been accounted for. Through much of the day, authorities declined to say how many died while they sorted out what happened.

Officials say two died, 10 were hospitalized and seven were hurt but refused treatment. The other 19 workers escaped.

Search-and-rescue experts worked into Monday evening to stabilize the building. It wasn't immediately clear whether their work would continue into Tuesday. (Associated Press)
