European Nations Issue Travel Advisories Following Death of CJNG Leader ‘El Mencho’
Multiple European governments have issued warnings to their citizens in Mexico following the death of Nemesio Oseguera Cervantes, known as “El Mencho,” the leader of the Cártel Jalisco Nueva Generación (CJNG). The alerts, issued on February 23, 2026, advise nationals to exercise extreme caution, register with their respective consulates, and in some cases, avoid non-essential travel within the country. The heightened advisories arrive after a large-scale operation by the Mexican military resulted in El Mencho’s death, sparking violence and unrest in several states, particularly Jalisco. The situation underscores the ongoing challenges Mexico faces in combating powerful drug cartels and ensuring the safety of both its citizens and foreign visitors.
The death of El Mencho, confirmed by the Mexican Fiscalía General de la República (FGR) through forensic analysis, marks a significant development in the fight against organized crime in Mexico. According to reports, the operation that led to his demise also resulted in the deaths of at least 27 security agents and 30 alleged cartel members. The CJNG, designated as a foreign terrorist organization by the U.S. Department of State, has been a major force in Mexico’s drug trade, known for its brutality and expanding influence beyond national borders. The organization, founded in 2009, has a presence not only throughout Mexico but also in the United States, Ecuador, Europe, Asia, Africa, and Oceania, according to information from Wikipedia.
The immediate aftermath of El Mencho’s death has been marked by retaliatory violence. Reports indicate that cartel members carried out arson attacks in various states, creating a climate of fear and uncertainty. The Spanish Minister of Foreign Affairs, José Manuel Albares, urged Spanish tourists and citizens currently in Mexico, especially in the Guadalajara consular district, to contact Spanish consulates to register their presence. More than 225,000 Spanish citizens reside in Mexico, making this a significant concern for the Spanish government. Albares made the appeal prior to participating in a meeting of EU Foreign Ministers in Brussels, highlighting the international attention the situation is receiving.
European Governments Respond to Escalating Security Concerns
Beyond Spain, other European nations have also taken steps to protect their citizens in Mexico. Portugal has advised its nationals to avoid unnecessary travel within the country, urging them to exercise “all cautions and prudence.” Portuguese Foreign Minister Paulo Rangel emphasized the “worrying” nature of the situation while speaking to the press in Brussels. The Portuguese Embassy in Mexico issued a similar warning on its social media channels. The embassy’s Facebook post details the advisory and encourages citizens to stay informed.
The United Kingdom has issued a strong recommendation for British citizens in Mexico to remain in their homes and avoid non-essential travel. The Foreign, Commonwealth & Development Office (FCDO) website details “serious security incidents” reported on February 22, 2026, across Jalisco state, including Guadalajara and Puerto Vallarta, following the operation against the CJNG in the municipality of Tapalpa. Authorities in Puerto Vallarta have issued a public alert urging residents to stay indoors. The FCDO advises those who must travel to do so by highway during daylight hours. This guidance reflects the heightened risk of violence and disruption in the region.
The Rise and Reign of ‘El Mencho’ and the CJNG
Nemesio Oseguera Cervantes, known as “El Mencho,” founded the CJNG in 2007 as an armed wing initially called Los Mata Zetas. The cartel gained prominence in 2011 and quickly became one of the most powerful and violent criminal organizations in Mexico. According to Wikipedia, the CJNG’s estimated size ranges from 18,800 to 32,000 members. El Mencho’s leadership was characterized by a ruthless pursuit of power and a willingness to engage in extreme violence, including homicide, torture, and fuel theft. The cartel’s activities extend beyond drug trafficking to include arms trafficking, money laundering, cybercrime, and contraband.
The CJNG has forged alliances with various criminal groups, including the Tijuana Cartel, the Gulf Cartel, Los Metros, Los Mexicles, Los Chapitos, Los Viagras, and the Caborca Cartel, strengthening its operational capabilities and expanding its reach. Conversely, the cartel has engaged in fierce conflicts with the Mexican government, including the Army, Air Force, and Navy, as well as with rival criminal organizations such as Grupo Flechas, La Línea, the Northeast Cartel, and numerous other groups. These conflicts have contributed to the high levels of violence and instability in Mexico.
International Cooperation in the Operation
The successful operation that led to El Mencho’s death was reportedly the result of close collaboration between Mexican and U.S. Authorities. President Claudia Sheinbaum confirmed that the operation benefited from information provided by the United States, highlighting the importance of international cooperation in combating transnational criminal organizations. This collaboration underscores the shared interest in disrupting the flow of drugs and dismantling the infrastructure of powerful cartels that pose a threat to both countries. The U.S. Government has long considered the CJNG a significant security threat, and has offered substantial assistance to Mexico in its efforts to counter the cartel’s activities.
The death of El Mencho does not necessarily signify the end of the CJNG. Experts caution that the cartel has a decentralized structure and a deep pool of potential leaders who could step in to fill the void. The organization’s financial resources and extensive network of contacts will likely enable it to continue operating, albeit potentially with some disruption in the short term. The Mexican government will need to maintain sustained pressure on the cartel to prevent it from regaining its former strength and influence. The coming weeks and months will be critical in assessing the long-term impact of El Mencho’s death on the CJNG and the broader security landscape in Mexico.
