(NewsNation) — Border officials are warning agents to wear body armor and remain vigilant after a violent episode in the El Paso sector, according to a bulletin NewsNation exclusively obtained.

The situation began at about 1 p.m. Sunday when Border Patrol was alerted to a stabbing. A National Guard soldier who was deployed from Indiana to the El Paso area under Operation Lonestar shot the suspect, who subsequently ran south to Mexico.

The stabbing victims suffered non-life-threatening injuries.

The bulletin warned of increased violence along the southern border and encouraged agents to wear body armor and remain vigilant.

The situation comes weeks after officials arrested four migrants charged with trying to cut through concertina wire installed along the Texas-Mexico border.

“They can attack an agent, and there’s literally no consequences,” said Art Del Cueto, vice president of the National Border Patrol Council.

Indiana’s National Guard said it’s aware of the situation and cares and supports for its soldiers deployed to the border.
