LORDSTOWN, Ohio (AP) - Four people were hospitalized late Friday after a small fire at the General Motors Lordstown plant.

GM says operations were back to normal Saturday. The facility was lightly staffed at the time.

In a release, the auto maker said the fire began just before 9 p.m. on Friday. The company said an early investigation traced the fire to welding work being performed by contractors.

Four people were taken to local hospitals. The company reported three were treated and released, with one remaining hospitalized.

A dispatcher for the Lordstown Police Department said firefighters were on site for about two hours.

The company said production would continue Monday with three regularly scheduled shifts.
