Mexico says it is addressing an environmental emergency after a train derailed not far from the Arizona border.

Mexico’s environmental protection agency says the freight train derailed over the weekend about 15 miles south of the Naco border crossing into Arizona.

The derailment caused a chemical spill of more than 15,000 gallons of sodium hydrosulfide. The chemical is used in different industrial processes, including mining.

Sonora is an important mining hub in Mexico, with multiple active copper mines in the area around the derailment.

Mexico says initial reports found no one was injured, but that the environmental protection agency and water authority will continue monitoring the area to determine the impact on the environment.
