(BREITBART) — by Brandon Darby & Ildefonso Ortiz
Border Patrol agents in the Rio Grande Valley Sector (RGV) of South Texas are being warned about risks posed to them on the border by “open warfare” including grenade attacks occurring on the Mexican side.
The warning echoes Breitbart Texas’s Cartel Chronicles reports on the bloody war occurring at the border between a faction of the Mexican Gulf Cartel and Mexican authorities.
The warning was issued by the National Border Patrol Council (NBPC) to agents in the RGV Sector. It reads:
WARNING ADVISORY TO BORDER PATROL AGENTS IN RGV SECTOR
Recent events in Tamaulipas, Mexico, specifically in and around the city of Reynosa, pose a special risk to U.S. Border Patrol agents working in the region.
The Reynosa faction of the Mexican Gulf Cartel recently lost its leader and the group is engaging in open warfare with Mexican authorities and possibly with rival factions or other transnational criminal groups. Open source reports indicate gunbattles and use of grenades and other explosives in the fighting.
Border Patrol agents working the line in any station’s area of operations immediately across the largely open border from Reynosa, Mexico, are advised to employ extra caution in the performance of their duties. Stray rounds from firearms have previously injured U.S. law enforcement personnel on the border.
