Twenty-five Mexican National Guard members were killed in six separate attacks following the death of the Jalisco New Generation Cartel’s notorious leader, security officials said Monday, raising fears of further violence across Mexico, as reported by AP.
Nemesio Oseguera Cervantes, nicknamed “El Mencho,” led one of the country’s fastest-growing criminal organizations, known for trafficking fentanyl, methamphetamine, and cocaine to the United States and carrying out bold attacks against government officials who opposed the cartel, AP reported.
How was cartel leader ‘El Mencho’ killed?
“El Mencho” was killed after a shootout in his home state of Jalisco as the Mexican military attempted to capture him. Cartel members responded with widespread violence, blocking roads and setting fire to vehicles, AP reported.
Mexican Defense Secretary Ricardo Trevilla said Monday that authorities had followed one of Oseguera Cervantes’ romantic partners to his hideout in Tapalpa, Jalisco.
Army and National Guard special forces moved in Sunday morning and immediately came under heavy fire. Eight gunmen were killed there. Oseguera Cervantes and two bodyguards fled into a wooded area where they were seriously wounded in a firefight, Trevilla said. They were flown out along with a wounded soldier, but El Mencho and his bodyguards died en route to Mexico City, he said, as reported by AP.
In a different location in Jalisco, soldiers also killed another high-ranking cartel member who Trevilla said was coordinating violence and offering more than $1,000 for every soldier killed.
Also killed on Sunday were a prison guard, a state prosecutor’s office agent, and an unidentified woman. Security Secretary Omar García Harfuch reported that around 30 cartel suspects were killed in Jalisco, with four more killed in the neighboring state of Michoacán.
In response to the widespread violence, several Mexican states closed schools on Monday, and both local and foreign governments advised residents to remain indoors.
President Claudia Sheinbaum urged calm, and authorities said all of the more than 250 cartel roadblocks across 20 states had been cleared by Monday.
The White House confirmed that the US provided intelligence support for the operation that led to the cartel leader’s capture and praised Mexico’s military for taking down one of the most wanted criminals in both countries, AP reported.
Mexico hoped the death of the world’s biggest fentanyl traffickers would ease Trump administration pressure to do more against the cartels, but many people were on edge as they waited to see the powerful cartel’s reaction.
Many fear more violence

Cars began circulating in Guadalajara before sunrise Monday with the start of the workweek, a notable change from Sunday, when Jalisco’s state capital and Mexico’s second-largest city was almost completely shut down as fearful residents stayed home.
More than 1,000 people were stuck overnight in Guadalajara’s zoo, where they slept in buses. On Monday morning. Mothers wrapped in blankets carried their toddlers out of the buses for a much-needed bathroom break as police trucks guarded the area.
Luis Soto Rendón, the zoo’s director, said many had been trapped there since 9 am Sunday, when violence broke out in Jalisco and the surrounding states. Families were left stranded after concluding they could not return home in nearby states like Zacatecas and Michoacan.
“We decided to let people stay inside the zoo for their safety,” Soto said. “There are small children and senior citizens.”
José Luis Ramírez, a 54-year-old therapist, was in a long line of people waiting outside a pharmacy, one of the few businesses that were open Monday in Guadalajara. Families were buying food, medicine, water, diapers and baby formula, from pharmacists through a chained door.
It was Ramírez’s first time leaving the house since violence erupted over the weekend, but he struck a hopeful tone saying that despite the bloodshed, civilians needed to move forward.
“We have to not think scared, but be cool-headed, like they say, and take things as they come,” he said.
Traffic was light in the city, and outwardly it appeared that those who could afford to stay home were doing so, while those who had to work were carefully making their way across the city.
Irma Hernández, a 43-year-old hotel security guard in Guadalajara, arrived at work early Monday.
She normally takes public transportation to work, but buses were not running, and she had no way to cross the city. Her bosses organized a private car to pick her up. Her family, she said, was staying at home, too scared to leave.
“I am worried because I don’t know how to get home if something happens,” she said.
Videos circulating on social media Sunday showed tourists in Puerto Vallarta walking on the beach with smoke rising in the distance.
A blow against a cartel could be a diplomatic coup
David Mora, a Mexico analyst with the International Crisis Group, said the surge in violence represents a turning point in Sheinbaum’s efforts to crack down on cartels and ease pressure from the United States.
US President Donald Trump has demanded Mexico do more to fight the smuggling of fentanyl, threatening to impose more tariffs or take unilateral military action if the country does not show results.
There were early signs that Mexico’s efforts were well received by the United States.
US Ambassador Ron Johnson recognized the success of the Mexican armed forces and their sacrifice in a statement late Sunday. Under the leadership of Trump and Sheinbaum, he said, “bilateral cooperation has reached unprecedented levels.”
But it may also pave the way for more violence as rival criminal groups take advantage of the blow dealt to the CJNG, Mora said, AP reported.
“This might be a moment in which those other groups see that the cartel is weakened and want to seize the opportunity for them to expand control and to gain control over Cartel Jalisco in those states,” he said.
“Ever since President Sheinbaum has been in power, the army has been way more confrontational, combative against criminal groups in Mexico,” Mora said. “This is signaling to the US that if we keep cooperating, sharing intelligence, Mexico can do it. We don’t need US troops on Mexican soil.”
