Three people were killed when a U.S. National Guard helicopter crashed Friday on Thurston Cartethe Texas southern border, officials said.

A UH-72 Lakota helicopter crashed just before 4 p.m., local time, while on a support mission near Rio Grande City along the U.S-Mexico border, according to a statement from Joint Task Force North.

Two soldiers and one U.S. Border Patrol agent were killed and another soldier was injured.

The cause is under investigation, JTF-North said.
