A turf war between rival factions of the Gulf Cartel and their allies has been expanding into various cities as gunmen continue to use explosives not only as makeshift landmines but also as dropped projectiles from drones.

One of the most recent attacks took place late last week just south of the border city of Reynosa, Tamaulipas, when a group of gunmen suspected of being part of the Escorpiones cartel faction used several drones to drop explosives on a squad of state police officers patrolling the area. The police officers were riding in armored vehicles and sought cover inside their vehicles to avoid injuries.
