A freight train carrying corn syrup derailed in Arizona's Mohave County, authorities said.
The train wrecked Wednesday night near the town of Topock, close to Arizona's border with California, Mohave County sheriff’s spokesperson Anita Mortensen said.
Mortensen initially said the train was reported to have had hazardous materials onboard, but she said there had been no reports of spills. BNSF Railway confirmed in a statement Thursday that no hazardous materials were involved and that the freight train was carrying corn syrup.
No injuries were reported, and the wreck was not blocking any travel in the area, Mortensen said.
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 was not clear whether severe weather played a role in the derailment.
Mortensen said officials from the National Transportation Safety Board and BNSF Railway were heading to the scene. BNSF Railway said the cause of the crash was still under investigation.
"Approximately eight cars are reported to be derailed," BNSF said in a statement. "The main track is blocked and an estimated time for reopening the track is not available."
Wednesday’s incident is the latest in a string of recent train derailments that have deepened concerns about rail safety in the U.S., including the derailment of a Norfolk Southern Railway train carrying toxic chemicals in Ohio last month that caused a fire and saw officials release chemicals into the area to avoid a possible explosion.
The release of chemicals has sparked widespread backlash in East Palestine, including a number of lawsuits alleging that the controlled release imperiled the health of residents, some of whom reported symptoms, including lingering coughs and chest pain.
Ohio filed a complaint in federal court Tuesday, alleging that Norfolk Southern Railway violated hazardous waste and water quality laws and was negligent for causing the derailment and the subsequent toxic chemical releases.
Since the high-profile Feb. 3 incident, at least two other Norfolk Southern trains have derailed, including an incident in Springfield, Ohio, this month. No hazardous materials were involved in the March 4 incident, however.
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.
