SALISBURY, N.C. (AP) — Two children died and two adults were injured in an overnight house fire in Salisbury.

The Salisbury Post reported Saturday that the Salisbury Fire Department and Rowan County Emergency Services were called to a home at about 12:30 a.m.

Upon arrival, flames and smoke were showing from the residence, but the fire was quickly extinguished.

At the time of the fire, four people were inside the home. Two children were dead when found by firefighters. An adult in the home was taken to Rowan Regional Medical Center with serious burns and later airlifted to Baptist Medical Center.

Details on the age of the victims or injured have not been released. One firefighter was treated on scene and taken to Rowan Regional Medical Center, out of an abundance of caution.

The cause of the fire has not yet been determined. The Salisbury Fire Marshal’s Office and Salisbury police are investigating.
