A freight train believed to be carrying hazardous materials derails in Mohave County, authorities said on Wednesday night.
The wreck happened near the town of Topock, close to Arizona's border with California, Mohave County Sheriff's Office spokeswoman Anita Mortensen said.
Mortensen said the train had been reported to have hazardous materials on board, but said there had been no reports of spills. It was not immediately clear which company the freight train belonged to.
According to Mortensen, no injuries were reported and the wreck was not blocking any travel in the area.
The cause of the derailment was not immediately clear.
A tornado warning had been issued for Topock until early Wednesday evening, according to the National Weather Service. It wasn't clear whether severe weather played a role in the derailment.
Wednesday's incident was the latest in a series of train derailments that have deepened concerns about rail safety in the United States.
Mortensen said officials from the National Transportation Safety Board and BNSF Railway were going to the scene of the derailment to investigate. The derailment of a Norfolk Southern Railway train carrying toxic chemicals in Ohio last month was a case of a fire and saw officials release chemicals into the local area to avoid a possible explosion.
The release of chemicals has sparked widespread backlash within the community of East Palestine, including a number of lawsuits alleging that the controlled release had a negative effect on the health of residents, with some reporting symptoms including lingering coughs and chest pain.
Ohio filed a complaint against Norfolk Southern Railway in federal court on Tuesday, alleging that the company violated hazardous waste and water quality laws and was negligent for the derailment and subsequent toxic chemical releases last month.
At least two other Norfolk Southern trains have suffered derailments, including an incident in Springfield, Ohio, earlier this month, since the high-profile Feb. 3 incident. There were no hazardous materials involved in the March 4 incident.
Several days later a Norfolk Southern train derailed in Calhoun County, Alabama, just hours before company CEO Alan Shaw faced lawmakers to answer questions about the February derailment.
