Authorities in southern New Mexico say a biofuel facility is on fire near the town of Anthony, and a half-mile area around the plant is being evacuated.
Dona Ana County officials say they've activated their emergency operations center and declared a hazardous materials emergency.
County spokesman Jess Williams says there's no word of any injuries so far, and the cause of the fire is not known. However, he says there has been a series of small explosions.
Fire crews from several agencies are on the scene, along with sheriff's deputies and New Mexico State Police.
According to Williams, the plant is known to have large quantities of methanol and other fuels and chemicals.
Anthony is on the New Mexico-Texas line, between Las Cruces, New Mexico, and El Paso, Texas.
