MEXICO CITY, Mexico (Diya TV) — Mexico faces rising tension after security forces killed one of the country’s most powerful drug lords in a high-stakes military operation backed by U.S. intelligence. The death of Nemesio “El Mencho” Oseguera Cervantes, leader of the Jalisco New Generation Cartel, has sparked violent clashes, travel disruptions, and fear in several regions, including popular tourist destinations.
Authorities confirmed that Mexican forces killed Oseguera on Sunday during a targeted operation. Officials said U.S. intelligence agencies supported the mission. His death marks a major blow to organized crime in Mexico, but it also triggered swift retaliation from suspected cartel members.
Security forces increased patrols across several states after the operation. In response, suspected gang members torched buses, blocked highways,s and attacked businesses. Witnesses described chaotic scenes that turned streets into what looked like war zones.
“It really did look and feel like a war zone,” said Travis Dagenais, who was visiting the region. “You just don’t know what could happen next.”
Authorities reported dozens of deaths linked to the unrest. Clashes between security forces and armed groups continued into Monday in some areas. Officials worked to regain control and restore public safety. President Claudia Sheinbaum addressed the nation and urged calm. She said authorities are maintaining “peace, security, and normalcy” across much of the country. Security forces remain on high alert in areas hit hardest by the violence.
Oseguera led the Jalisco New Generation Cartel, one of Mexico’s most powerful criminal organizations. The cartel controls major drug trafficking routes and plays a key role in smuggling fentanyl, methamphetamine,e and cocaine into the United States.
U.S. authorities had offered millions of dollars for information leading to Oseguera’s capture. Law enforcement agencies on both sides of the border linked him to widespread violence and drug trafficking operations. Security analysts say his death could weaken the cartel’s leadership. However, they also warn that power struggles within the group may fuel more violence in the short term.
The unrest disrupted travel plans for hundreds of visitors. Several airlines suspended flights to and from affected cities, including the beach resort of Puerto Vallarta. Some routes remain canceled, while others are set to resume serviceon Tuesday. Tourists described tense moments as hotels advised them to stay inside. Colleen Echohawk, an American visitor, said hotel staff warned her group not to head to the airport during peak unrest.
“We’re just going to be patient and support each other,” Echohawk said. “We’ll try to get out of here as soon as we can.”
David Miranda, another traveler, described scenes that felt like “a movie.” He said the situation frightened many visitors who had expected a relaxing vacation.
The U.S. State Department urged American citizens in certain parts of Mexico to shelter in place. Officials activated a 24-hour crisis hotline after airlines suspended flights and travelers sought guidance. The department fielded hundreds of calls from concerned citizens.
Authorities advised travelers to monitor official updates, follow instructions from local officials, and avoid areas with active security operations. Some regions have already returned to normal business activity, while others remain under tight security. Travel experts recommend that stranded passengers contact their airlines for rebooking options and check travel insurance coverage. They also urge visitors to stay in secure accommodations until officials declare the area safe.
Mexico has faced waves of cartel violence for years. The killing of a high-profile leader often creates short-term instability. Security forces continue to patrol affected cities and investigate the latest attacks. President Sheinbaum pledged to strengthen security and protect civilians. She emphasized cooperation with U.S. authorities to combat drug trafficking and organized crime.
For now, many residents and visitors wait for calm to fully return. Authorities say they will provide updates as the situation evolves. Travelers and local communities hope stability will follow this dramatic chapter in Mexico’s ongoing fight against cartel violence.
