At least two people were injured after a gunman opened fire at a northern New Mexico high school Thursday morning. Law enforcement said the shooter is down. 

The San Juan County Sheriff’s Office confirmed reports of an active shooter around 9 a.m. local time, saying Aztec High School in Aztec, N.M. was on lockdown.

"There are at least a dozen reported injuries at this time," a spokesperson for the sheriff's department told Fox News.

The school is located  in the Four Corners region and is near the Navajo Nation, about 180 miles north of Albuquerque.

A spokesman with the sheriff’s office told reporters that the unidentified shooter was "down," but did not provide additional information.

No additional information was provided on the condition of those injured, KOB reported.

It wasn't immediately clear if the shooting happened inside the school, who was suspected of firing the shots and what condition the wounded were in.

On Facebook, law enforcement asked people to “avoid the area” while they secured the scene.

“Aztec High School is locked down and being evacuated. Please avoid the area. Parents can stage at 516 and Mesa Verde near the church to pick up their kids. We will update this as we learn more,” the post said.

Farmington Municipal Schools wrote on Facebook all schools in the district went into preventive lockdown due to the incident.

“We have no reason to think there is any threat in Farmington at this time, but we are taking this advance action in order to secure all of our schools. Your students’ safety is our primary concern,” the statement said.

In nearby Bloomfield, police said local schools were also lockdown as a precaution.
