UK Foreign Office Issues Urgent Mexico Travel Warning Amid Cartel Violence
The UK Foreign Office has issued an urgent travel warning for Mexico following a surge in drug cartel violence that has led to widespread flight cancellations and left many thousands of tourists stranded in popular resorts. The violence erupted in the southwestern state of Jalisco after the killing of a notorious drug cartel leader, prompting authorities to advise travellers to stay indoors and avoid non-essential travel.
Violence Erupts After Cartel Leader Killed
Nemesio Oseguera Cervantes, widely known as "El Mencho" and the leader of the Jalisco New Generation Cartel (CJNG), was killed during a Mexican military operation with US assistance in the town of Tapalpa. In the immediate aftermath, revenge attacks have broken out across Jalisco, including incidents at Guadalajara airport, where social media footage showed passengers seeking cover as armed gunmen opened fire.
The Foreign Office warning states: "Serious security incidents have been reported on 22 February across the state of Jalisco, including in Guadalajara and Puerto Vallarta, following a federal law-enforcement operation against organised crime in the municipality of Tapalpa. Authorities in Puerto Vallarta have issued a public advisory to stay indoors. Routes to airports may be blocked. Incidents are also being reported in other parts of the country. You should exercise extreme caution, follow local authorities’ advice, including orders to stay indoors and avoid non‑essential travel in affected areas."
Flight Cancellations and Tourist Strandings
As a result of the violence, numerous flights to and from the Pacific resort of Puerto Vallarta and the World Cup 2026 host city of Guadalajara have been diverted or cancelled. At least 30 flights from US, Mexican, and Canadian airports to Puerto Vallarta have either returned to their points of origin or been rerouted to alternative airports, with dozens more cancellations reported. This has left thousands of tourists in Puerto Vallarta stranded, unable to depart as planned on Sunday.
Puerto Vallarta airport issued a statement on social media confirming that all international operations and most domestic flights were cancelled by airline decision. The statement urged passengers to remain calm and follow instructions from airport personnel, noting that the airport remains under the protection of the National Guard and the Ministry of National Defense.
International Responses and Expert Warnings
The US Embassy in Mexico City has also urged American citizens in Jalisco and other affected areas to "shelter in place until further notice," citing ongoing security operations, road blockages, and criminal activity. Airlines such as Air Canada have temporarily suspended operations in Puerto Vallarta, advising customers not to attempt to travel to the airport unless their flights are confirmed as operating.
An expert from the conflict monitoring group Acled, Sandra Pellegrini, warned that the killing of El Mencho could lead to further instability. "The killing of CJNG leader Nemesio Oseguera Cervantes marks a significant operational development for Mexican forces, but the reported immediate highway blockades and arson attacks show how quickly cartels can mobilise retaliation to demonstrate continued control. Past cases suggest leadership removals rarely reduce violence long term, and instead often trigger instability as factions compete for power," she said.
Impact on British Holidaymakers
The latest warning primarily affects areas in Jalisco, with the main resorts for British holidaymakers on the Caribbean coast, such as Cancun, remaining largely unaffected as they are located approximately 1,000 miles away. Flights from the UK to Cancun, including services from Tui, British Airways, and Virgin Atlantic, are operating normally, with cancellations only occurring on routes to and from Guadalajara due to the security situation.
However, the Foreign Office has updated its advice to caution that security incidents have been reported in other parts of Mexico, urging all travellers in the country to stay alert and follow local security advice. The FCDO already warns against travel to many regions of Mexico due to drug-related violence, highlighting risks such as being caught in crossfire or mistaken for gang members.
This incident underscores the ongoing challenges posed by organised crime in Mexico and the potential for rapid escalation following high-profile law enforcement actions. Travellers are advised to monitor official guidance closely and reconsider plans in light of the volatile security environment.
