Mexican authorities fear retaliatory violence after the killing of Gulf Cartel kingpin Ezequiel Cárdenas Guillén AKA "Tony Tormenta" in a three-hour shootout with soldiers in Matamoros, Tamaulipas state, on Nov. 5. Three cartel gunmen, two members of the security forces and a journalist were also killed in the gun-battle. The federal army used 300 grenades in the battle, leaving several local buildings badly damaged. Local homes have since put up signs reading "Por favor—No lanzar granadas" (Please don't throw grenades). Municipal authorities report receiving telephone bomb threats aimed at Matamoros schools.
