At least four people have been killed and several others injured in a shooting in the US.
Police in Farmington, New Mexico, said they believe the attacker, who was "confronted and killed on scene", acted alone.
"The suspect's identity is unknown and there are no other known threats at this time," the police department said in a Facebook post.
The police said at least three civilians were killed in the shooting on Monday and more were wounded.
Two police officers were also shot in an exchange of gunfire with the suspect - one city police officer and one with the New Mexico state police.
Both were in a stable condition.
The shooting was reported shortly after 11am in the Brookside Park area of the city.
Schools in the city were put on lockdown on Monday. Three remained in emergency lockdown while others were placed in what officials called "preventative lockdown".
Farmington Police Department, San Juan County sheriff's office, and the New Mexico State Police are investigating the shooting.
An official at the San Juan County sheriff's office called the incident "an open and active ongoing investigation".
Farmington has a population of around 46,000 residents and is in northwestern New Mexico, near the Four Corners region.
It is around 180 miles (290km) northwest of the state's largest city Albuquerque.
