SANTA TERESA, N.M. (AP) — New Mexico authorities said an unknown hazardous materials release has sickened about 200 people near the Mexican border just northwest of El Paso, Texas
A mandatory evacuation is under way for two miles around the Dona Ana County Industrial Park and the Santa Teresa Port of Entry south of Las Cruces.
Officials said 200 people are in triage for symptoms of light-headedness, nausea and dizziness, but no serious injuries have been reported, and no one has been sent to the hospital.
A system has been activated to alert people in nearby homes and businesses to stay indoors, seal all doors and windows and turn off air conditioning and heating systems that bring in outside air.
Authorities are still investigating what material has been released and from where.
