(BREITBART) — MATAMOROS, Tamaulipas — Mexico’s Gulf Cartel managed to build a training camp in this border city with guard towers, walls, drill areas, and a garage for outfitting vehicles with armor plating.
The camp was discovered by the Mexican Army during an enforcement operation in the rural areas southwest of Matamoros. Military personnel received anonymous information about a cartel camp and carried out a series of efforts to locate the training facility, information provided to Breitbart Texas by the Mexican Army revealed. Matamoros is a border city immediately south of Brownsville, Texas.
Cartel forces in Matamoros set up a series of blockades throughout the city to keep soldiers from reaching the camp. By the time that the Mexican army reached the walled facility, cartel gunmen managed to flee leaving behind weapons, tactical gear, armored vehicles, and other items.
The compound was surrounded by a wall and had a concrete guard tower used by lookouts to warn about any approaching rival forces. Inside, authorities found multiple structures including garages, workshops, and target ranges.
