WELLS, Nev. (AP) — A 60-mile stretch (96 kilometers) of U.S. Interstate 80 in northeast Nevada has been closed while emergency crews respond to a train derailment. Authorities were investigating whether any hazardous materials were aboard the train.

There’s been no immediate report of injuries.

Nevada Department of Transportation spokeswoman Meg Ragonese says the interstate was closed along the Utah state line shortly after the derailment was reported at about 11 a.m. Wednesday.

A dispatcher at the Elko County Sheriff’s Office says rail cars containing military munitions are on the train, but not near the site of the actual derailment.

Ragonese says interstate traffic is being rerouted.
