Nemesio Oseguero Cervantes, also known as "El Mencho," was a major cartel kingpin in Mexico who was wanted by United States authorities. He was killed in a Mexican military raid in Jalisco on Feb. 22, 2026.

The day after the killing of a major cartel kingpin by Mexican authorities, the country is taking stock of a day of retaliatory violence.

Sonora, the Mexican state south of Arizona, has so far been largely spared from the spate of violence that spread through many parts of Mexico on Sunday.

Elsewhere in Mexico, cartel members blocked roads and burned buildings after the Mexican army killed the leader of a major drug cartel in a United States-backed raid in the state of Jalisco.

Nemesio Oseguera Cervantes, known as “El Mencho,” was the kingpin of the Jalisco Nueva Generación cartel. He was one Mexico’s most powerful cartel boss and one of the United States’ most wanted fugitives.

The U.S. State Department issued a travel advisory for U.S. citizens to shelter in place in five Mexican states Sunday, while flights were canceled to the major tourist destination of Puerto Vallarta. Videos from the Jalisco tourist hub showed fires around the resort town.

Mexico said Sunday that it used intelligence from the United States to carry out the raid.

“There’s respect for our sovereignty, which has always been maintained, including yesterday,” Mexican President Claudia Sheinbaum told reporters.

Mexico’s security secretary said Monday that 25 Mexican troops died in Sunday’s raid.
