SEDENA Activates Plan DN-III-E in Zacatecas Following Ojocaliente Car Bomb, Deploys 'Genaro Codina' Task Force

On September 2, 2026, Infobae reported that Mexico's Secretariat of National Defense (SEDENA) activated Plan DN-III-E — its civil-assistance disaster-response protocol, in force since 1965 — in Ojocaliente, Zacatecas, in response to the August 30 car bomb attack on the municipal police headquarters attributed to CJNG. Under the plan, the Army and National Guard support debris removal, temporary shelter administration, damage assessment and registration, evacuation, and area security, working alongside civilian authorities. A 'Genaro Codina' task force was stood up integrating the Army, National Guard, and other security agencies, with the commander of the Fifth Military Region traveling to Zacatecas to reinforce operations with additional personnel from other states. The deployment followed updated official figures putting the bombing's toll at 11 injured and roughly 40 homes affected (about 15 requiring structural evaluation), and came a day after the first suspect, Juan Pedro 'N,' was detained in Cuauhtémoc municipality.
