Mexico in May 2026: the most important developments in security
Mexico's security in May 2026 was dominated by US pressure and the role of US agencies on Mexican soil. On May 13, CNN reported that the CIA facilitated the killing of a Sinaloa Cartel operative in Mexico. The CIA had denied such a role, and President Claudia Sheinbaum dismissed the story as fiction. Further reports described the agency's growing presence in Mexico, and the DEA and the Pentagon were reported to have joined threats against the country. Earlier, on May 6 and 7, President Donald Trump renewed the threat of US military action against cartels if Mexico does not act, and the US Attorney General said more charges against Mexican politicians were coming. On May 8, Trump said cartels rule Mexico.
US legal action reached Mexican officials directly. On May 15, the former finance secretary of Sinaloa state turned himself in to US authorities and the state's former security secretary was arrested in Arizona, while allies of the Sinaloa governor were reported to be in US custody on drug charges. On May 18, Mexico froze the bank accounts of former officials investigated by the US, and on May 20 the US sanctioned a Mexican network accused of laundering money for the Sinaloa Cartel. Enrique Inzunza denied having had contact with US authorities.
Violence continued inside Mexico. Ten people were killed in a shooting in Tehuitzingo, Puebla, on May 17, and no suspects were named. Drug gang attacks were reported to have forced hundreds of Indigenous families to flee their homes, and violence reached hospitals. Authorities arrested a regional leader of the Jalisco New Generation Cartel in Baja California, a cartel recruiter in Teuchitlan and a nephew of Joaquin Guzman in Sonora, and the EU expanded charges against the cartel's second-in-command. Organized crime was reported to have opened a new sea smuggling route between Mexico and Guatemala. On May 20, a US military surveillance blimp on loan to Customs and Border Protection was lost at the southern border, and its wreckage was found in Mexico.
