ROANOKE RAPIDS, N.C. (WNCN) – Four people are confirmed injured in a Roanoke Rapids paper mill explosion Thursday afternoon, its fire department told CBS 17.

Roanoke Rapids Fire Chief Jason Patrick tells CBS 17 that those injured are suffering from what appears to be steam burns, but the investigation remains ongoing, after his team responded to the 100 block of Gaston Road at approximately 1:30 p.m.

He also said the people suffering from injuries were transported from West Rock Paper Mill Company to a nearby hospital.

“We had a machine blow up at the West Rock,” audio provided by Broadcastify said after 10 p.m. “Just to make you aware, we have an unknown number of people hurt.”
