Mexico has deployed 10,000 troops to contain violence following the killing of cartel leader Nemesio Oseguera, widely known as “El Mencho”, in Jalisco state, as clashes and unrest spread across multiple regions.
The Mexican army confirmed that Nemesio Oseguera, 59, leader of the Jalisco New Generation Cartel (CJNG), was wounded during a shootout with soldiers in the town of Tapalpa on Sunday and died while being transported by air to Mexico City. He had a $15 million bounty placed on him by the United States.
News of his death triggered widespread retaliatory violence. Authorities reported that cartel members blocked roads in 20 states and set fire to vehicles and businesses. During the operation and subsequent clashes, at least 27 members of the security forces, 46 suspected criminals and one civilian were killed.
In Jalisco, a prison was attacked by armed groups, resulting in the escape of at least 23 inmates, according to the state security secretary.
The federal government reinforced security in Jalisco by deploying an additional 2,500 troops, bringing the total number of personnel sent since Sunday to 10,000. The move aims to stabilise the region, which is set to host four FIFA World Cup matches this year.
Residents in affected areas reported blockades and smoke rising from burning vehicles. In Aguililla, in Michoacán state, which is Oseguera’s birthplace, early morning roadblocks were reported. In Guadalajara, schools remained closed, and most public transport services were suspended. Many businesses, pharmacies and shops did not reopen on Monday as residents stocked up on basic supplies.
The violence also reached the resort city of Puerto Vallarta, a major tourist destination. The United Kingdom, Canada and the United States issued travel warnings, while Australia advised its citizens to exercise caution. Dozens of flights to and from Mexico were cancelled by US and Canadian airlines.
Security analysts have warned that Oseguera’s death could create instability within CJNG. His son, Ruben Oseguera Gonzalez, known as “El Menchito”, was convicted by a federal jury in Washington in September. Experts suggest the absence of a clear successor could trigger internal power struggles.
David Mora, an analyst at Crisis Group, said the leadership vacuum could lead to violent realignments within the organisation.
Mexican authorities stated that intelligence from the United States supported the operation. White House Press Secretary Karoline Leavitt confirmed that Washington provided intelligence assistance. President Claudia Sheinbaum emphasised that no US forces were involved in the raid.
Mexico’s Defence Secretary Ricardo Trevilla said the location of Oseguera was traced through intelligence indicating a meeting with one of his associates at a ranch in Jalisco. During the operation, two suspected cartel members were arrested, and weapons were seized, including rocket launchers capable of targeting aircraft and armoured vehicles.
Authorities also announced the death of Oseguera’s associate, known as “El Tuli”.
The United States has designated CJNG as a terrorist organisation and accuses it of trafficking cocaine, heroin, methamphetamine and fentanyl into US territory. The operation comes amid continued pressure from President Donald Trump for Mexico to curb drug flows into the United States or face potential tariff measures.
Security operations remain ongoing as authorities seek to restore order and prevent further escalation across western Mexico.
