Two people were killed and at least ten injured Monday after an explosion at a Nebraska plant caused it to partially collapse.

The Omaha-based plant for International Nutrition, which manufacturers animal nutritional supplements, partially collapsed after an explosion Monday morning, trapping some workers inside, the Associated Press reports. Omaha police said two people died in the accident and the remaining workers were accounted for, according to the AP.

It was still unknown Monday afternoon how many were trapped inside, but workers were reportedly emerging from the collapsed building as search teams entered the building.

Thirty-eight people were inside the building when it collapsed. Ten have been taken to the hospital, and four are in critical condition.
