The Mexican government said it killed the nation’s most wanted cartel boss on Sunday, setting off a wave of fires and violence across the country as cartel operatives sought to exact revenge in an unsettling show of force.

 

Nemesio Oseguera Cervantes, known as “El Mencho,” was the longtime leader of one of Mexico’s most powerful cartels, the Jalisco New Generation Cartel, and was widely regarded as one of the country’s most violent criminal figures. He presided over a criminal enterprise that has expanded rapidly over the past decade, producing and selling drugs, extorting local businesses and terrorizing communities across the country.

 

Mr. Oseguera’s killing plunged Mexico into a highly tense moment that could unleash a surge in violence. Past captures of cartel leaders have set off wars between the government and cartels, as well as between opposing factions jockeying for power in the beheaded criminal group.

 

Those fears were heightened on Sunday by a swift outbreak of violence across Mexico. In states around the country, armed groups blocked roads and set fire to supermarkets, banks and vehicles, in one of the most widespread eruptions of turmoil in the nation’s recent history.

 

Mexican security forces on Sunday captured Mr. Oseguera in Tapalpa, a town of about 20,000, in the western coastal state of Jalisco, where his cartel was founded and based, the government said in a statement. Mr. Oseguera was injured in the operation and died while in transport to Mexico City for medical attention, according to the government. At least nine other cartel members were killed.

Mr. Oseguera’s killing is a major victory in Mexico’s new offensive against drug cartels and it could help reduce pressure from President Trump, who has been threatening strikes in Mexico. The Mexican government said the United States had contributed intelligence that aided the operation against Mr. Oseguera. U.S. officials said that it was a Mexican operation and that no American troops were involved in the operation.

 

That was only the start for Mexican security forces on Sunday. They were deployed across the country to confront the backlash over Mr. Oseguera’s killing.

 

In at least 13 states, apparent cartel operatives sought to cause havoc by setting fires and blocking roads with burning vehicles. Cartels have often lashed out following the capture of their top bosses in a bid to show their power and discourage the authorities from confronting them again.

 

In the state of Jalisco alone, officials said 20 branches of the state-run bank had been set ablaze or damaged, while groups ignited cars to block more than 20 roads. Jalisco officials said they had suspended public transportation in some areas and warned hotels to instruct their guests to remain inside, including in Puerto Vallarta, the beachside city popular with American and Mexican tourists.

 

Much of the violence occurred in Guadalajara, Jalisco’s capital, a hub of 1.4 million people that is a host city for this year’s World Cup. Panic broke out at Guadalajara International Airport on Sunday, with videos posted on social media showing airport staff and travelers fleeing the building. The airport and Mexican federal government said that the airport was operating as normal and that there was no risk to fliers.

 

Concerts and soccer matches were canceled. Flights were diverted. And at least one port halted operations. The unrest also already had affected the week ahead, as some states canceled classes on Monday, while airlines and bus operators suspended some routes this week.

 

The U.S. government warned its citizens to “shelter in place until further notice” in parts of five states: Jalisco, Tamaulipas, Michoacán, Guerrero and Nuevo León. Various airlines issued travel advisories or halted flights.

 

President Claudia Sheinbaum urged Mexicans to remain calm. “There is complete coordination with all the state governments,” she said online. “We must stay informed and calm. Activities are proceeding normally across most of the country.”

 

Paulina, 32, a Guadalajara resident who asked to be identified by only her first name because she feared for her safety, said she was traveling with her husband and 3-year-old son on a planned Sunday outing when they became trapped by one of the cartel’s roadblocks. As they tried to escape and get home, they saw a wounded family on the side of the road, she said.

 

“I’m begging people not to go out,” Paulina said. “After what I saw, I realized these people have no consideration for anyone. I wouldn’t wish what I witnessed on anyone.”

 

By Sunday afternoon, Guadalajara had fallen eerily quiet. Streets were largely deserted, and most businesses, including gas stations, had shuttered as residents stayed indoors.

 

There was similar violence in Puerto Vallarta.

 

Dalia, 32, a local resident who also requested that her last name be withheld, said she was out getting breakfast when she saw a group of armed men force a driver off a city bus and then light it on fire.

 

“The cars behind it began frantically reversing, and suddenly I saw there were about 20 people — all hooded and dressed in black — who started dousing the area with gasoline and setting it ablaze,” she said. “We all started running back home along the avenue, and hooded people on motorcycles just kept passing us.”

 

The unrest also hit other tourist hubs, such as Cancún and Playa del Carmen, on Mexico’s Yucatán Peninsula, where groups set fires to supermarkets, according to videos posted online and verified by The New York Times.

 

Vanda Felbab-Brown, an expert on nonstate armed groups at the Brookings Institution, said the significance of Mr. Oseguera’s killing rivaled that of the capture of the Sinaloa Cartel leader Joaquín Guzmán Loera, known as “El Chapo,” in 2016, or of his former partner Ismael Zambada García, known as “El Mayo,” in 2024.

 

She said that the early bursts of violence also echoed the fallout in Sinaloa in 2019, when Mexican forces captured Ovidio Guzmán López, a son of El Chapo. Within hours, heavily armed gunmen paralyzed Culiacán, unleashing gunfire in broad daylight and forcing the government to release him.

 

Whether the turmoil now spreads further, she said, will depend on whether leaders of the Jalisco cartel have established a clear line of succession capable of holding the organization together. Otherwise, the vacuum left by Mr. Oseguera’s death could trigger a fracturing of the group and a new wave of bloodshed, she said.

 

The Jalisco cartel grew into one of Mexico’s dominant trafficking organizations under Mr. Oseguera’s command, battling rivals across multiple states while moving synthetic drugs, including cocaine, methamphetamine and, in recent years, fentanyl into the United States.

 

His death is likely to improve the Mexican government’s relations with Washington. Mr. Trump has been pressuring Mexico to combat the cartels more forcefully and threatening military strikes against the groups if he is not satisfied with the results.

 

Ms. Sheinbaum has firmly and repeatedly rejected that proposal, saying any U.S. strikes would violate Mexico’s sovereignty. At the same time, her government has expanded its cooperation with American security agencies, including on intelligence.

 

Christopher Landau, the American deputy secretary of state and a former U.S. ambassador to Mexico, congratulated the Mexican security forces for killing Mr. Oseguera. “This is a great development for Mexico, the US, Latin America, and the world,” he posted online. “The good guys are stronger than the bad guys.”

 

As part of the operation, Mexican forces captured two other cartel members, as well as various weapons and armored vehicles, including what officials described as “rocket launchers capable of downing aircraft and destroying armored vehicles.”

 

Three members of the Mexican security forces were injured in the operation, the government said.

 

The U.S. State Department had offered up to $15 million for information leading to Mr. Oseguera’s arrest or conviction. He was one of Washington’s most sought-after targets and had been indicted multiple times in the United States on federal drug charges.

 

But for years, he had managed to evade capture and had cemented a reputation as one of the world’s most elusive criminal bosses.
