LEEDS, Ala. (AP) — Several workers were injured and others needed help getting out of the rubble when a roof collapsed Thursday at a clothes hanger factory, company officials said.

Ambulances took the injured workers to hospitals after the collapse at M&B Hangers shortly after 9 a.m. in Leeds, near Birmingham.

About 40 people were inside the plant, but none of the injuries appeared to be life-threatening, President and CEO Milton Magnus said.
