Irish citizens traveling to Mexico are being urged to exercise extreme caution, with the Department of Foreign Affairs advising against all travel to parts of Jalisco state, including the popular tourist destinations of Puerto Vallarta and Guadalajara. The updated travel advisory comes following a period of intense security operations sparked by the death of Nemesio Oseguera, known as “El Mencho,” the leader of the Jalisco New Generation Cartel (CJNG).
The situation unfolded rapidly on Monday, February 23, 2026, when Mexican special forces apprehended Oseguera after he was injured during a military operation in the town of Tapalpa, located on Mexico’s Pacific coast. According to Mexico’s defense ministry, Oseguera died while in custody. His death has triggered widespread retaliatory violence and a heightened security presence across the region, prompting travel warnings from multiple governments, including the United States and Canada.
The Irish Department of Foreign Affairs stated that citizens already in Jalisco or other affected areas should “shelter in place, avoid unnecessary movement, and follow the direction of the local authorities.” This guidance reflects the volatile security landscape and the potential for further unrest in the wake of El Mencho’s death. The advice underscores the importance of prioritizing personal safety and adhering to instructions from local law enforcement.
The United States State Department has issued similar guidance, urging American citizens in parts of Mexico to shelter in place due to ongoing security operations, road blockages, and criminal activity. A statement released via X, formerly known as Twitter, advised citizens to remain sheltered until further notice. Roadblocks have significantly disrupted travel, leading to the cancellation of both domestic and international flights in Guadalajara and Puerto Vallarta.
Due to ongoing, widespread security operations and related road blockages and criminal activity in many areas of Mexico, US citizens should shelter in place until further notice. Roadblocks have impacted airline operations, with some domestic and international flights cancelled in both Guadalajara and Puerto Vallarta. https://t.co/…
Impact on Travel and Airlines
The disruption to air travel has been substantial. Several US and Canadian airlines have cancelled flights to affected areas, and some planes have been forced to turn back mid-flight. Southwest Airlines confirmed it turned back four flights originally bound for Puerto Vallarta and is preparing to deploy aircraft to repatriate stranded passengers and staff once the situation stabilizes. The airline has not yet specified a timeline for resuming normal operations.
The $15 million (€12.7 million) US bounty placed on Oseguera’s head highlights the significance of his capture and the potential for continued instability as the CJNG navigates a leadership transition. The cartel, known for its increasing power and violence, has become a major force in Mexico’s criminal landscape.
International Response and Regional Concerns
Canada has also issued travel advisories, urging its citizens in Mexico to “keep a low profile and follow advice of local authorities.” Specifically, Canadians have been advised to shelter in place in the states of Michoacan, Guerrero, and Jalisco, citing reports of “shootouts with security forces and explosions.” This coordinated response from multiple nations underscores the seriousness of the situation and the potential for broader regional implications.
The events in Jalisco are not isolated. Mexico continues to grapple with widespread violence linked to drug cartels, posing significant challenges to both the government and the safety of its citizens and visitors. The recent escalation serves as a stark reminder of the risks associated with travel to certain regions of the country.
Understanding the Jalisco New Generation Cartel
The Jalisco New Generation Cartel (CJNG) has rapidly risen to prominence in recent years, challenging the dominance of more established cartels. Known for its aggressive tactics and sophisticated operations, the CJNG has expanded its influence across Mexico and into the United States. El Mencho’s leadership was instrumental in the cartel’s growth, and his death is expected to trigger a power struggle within the organization.
The cartel’s activities include drug trafficking, extortion, kidnapping, and violence against rival cartels and government forces. Its control over key transportation routes and strategic territories has made it a formidable opponent for Mexican authorities.

Irish citizens in Mexico requiring assistance are advised to contact the Irish Embassy in Mexico City or the Department of Foreign Affairs in Dublin.

Authorities are continuing to monitor the situation closely, and further updates will be provided as they become available. The immediate priority remains ensuring the safety and security of both residents and visitors in the affected areas.
The situation remains fluid, and travelers are strongly encouraged to stay informed and heed the advice of local authorities.
