El Mencho’s reported death triggers cartel violence that shuts down parts of western Mexico
Large parts of western Mexico were brought to a standstill after authorities said Nemesio Rubén Oseguera Cervantes, known as “El Mencho” and alleged leader of the Jalisco New Generation Cartel (CJNG), was killed during a military operation in Jalisco state, triggering widespread retaliatory violence.
Officials and international advisories warned of road blockades, vehicle arson and disruptions to travel as security forces worked to restore order, particularly in and around Guadalajara and the Pacific coast resort of Puerto Vallarta.
El Mencho killing sparks wave of roadblocks and arson
Mexico’s security forces said the operation took place in Tapalpa, Jalisco, where troops came under attack during an attempt to capture Oseguera Cervantes. Authorities reported that he died from wounds sustained in the confrontation.
In the immediate aftermath, authorities reported around 250 roadblocks across 20 states, with vehicles set on fire and major roads blocked. President Claudia Sheinbaum urged calm as officials said most blockades had been cleared by late Sunday.
Schools closed and public transport disrupted in Jalisco
Local authorities in Jalisco announced emergency measures including the suspension of in-person classes in some areas as the unrest unfolded. In Guadalajara, residents reported severe disruption as traffic and public activity dropped sharply amid security warnings.
Guadalajara is scheduled to host matches at the 2026 FIFA World Cup.
Travel warnings issued as flights and ground transport affected
The UK government’s travel advice warned that authorities in Puerto Vallarta had issued a public advisory to stay indoors and said routes to airports could be blocked, urging travellers to follow local instructions and avoid non-essential travel in affected areas.
US advisories also urged citizens to shelter in place in several regions as violence and road closures affected movement, including in parts of Jalisco.
US intelligence support confirmed; reward details reiterated
US officials confirmed intelligence support for the operation, and US authorities have long offered a reward of up to $15 million for information leading to Oseguera Cervantes’s capture.
The CJNG has been identified by US authorities as a major trafficking organisation linked to fentanyl and other drugs, and Washington has pressed Mexico to intensify operations against groups supplying the US market.
Death toll estimates vary as authorities assess casualties
Early casualty figures differed across reporting, with the Associated Press reporting at least 14 deaths linked to the unrest, while El País reported broader disruption and the scale of the blockades while authorities continued to verify impacts across states.
Mexico’s federal government said security forces were continuing operations to stabilise affected areas, while officials warned that conditions could change rapidly as investigations and patrols continue
