Unknown cartel gunmen operating in a known drug smuggling corridor in Southern Arizona fired multiple shots at an on-duty U.S. Border Patrol agent overnight.

UPDATE — 8 p.m. MST: U.S. Customs and Border Protection officials provided the following update:

An agent assigned to a mobile surveillance unit near Hereford Road heard several shots fired and observed two unknown individuals with a rifle at a distance. An unoccupied Border Patrol vehicle next to the surveillance unit was struck by bullets. The agent was not injured and did not return fire. Multiple Customs and Border Protection (CBP) agents and law enforcement responded to the area in an effort to locate the suspects. The suspects fled the area on foot and have not been located.

The agent was patrolling the area near the Brian Terry station in southern Arizona when unknown gunmen began firing. Cochise County Sheriff’s deputies and other Border Patrol agents arrived to the scene to carry out a manhunt for the suspected cartel gunmnen.

Arizona local law enforcement officials confirmed they were not able to apprehend the cartel gunmen but continue investigating the attack.
