Mexico’s Navy reports 1,149 kg seizure off Chiapas and Oaxaca

Mexico’s Navy reported on November 5, 2026, that it seized 32 packages in two Pacific operations off Chiapas and Oaxaca and detained one person. The approximate combined weight was 1,149 kilograms including packaging; the government said the substance had characteristics similar to cocaine and that its final ministerial weight remained pending confirmation.

Two seizures off Chiapas and Oaxaca

A joint statement from Mexico’s Security and Citizen Protection Secretariat and the Navy said the first operation involved 16 packages weighing about 629 kilograms. A second involved 16 packages weighing about 520 kilograms. Authorities described the contents as a substance similar to cocaine, rather than giving a confirmed chemical identification.

Detention and the government’s estimate

Authorities said the detained person was read their legal rights and handed over with the suspected drugs to the Federal Attorney General’s Office, with support from the Security Secretariat, to prepare investigation files. The statement did not identify the person.

The government estimated the seizures’ economic impact on criminal groups at 272,898,198 pesos. Security Minister Omar García Harfuch confirmed the operations on social media, Mexico News Daily reported. He described each seizure as a direct blow to criminal-group finances, saying it reduced resources to buy weapons, corrupt and generate violence, and meant fewer drugs on the streets. The impact figure is the government’s estimate.

How the seizures fit Mexico’s maritime operations

The Navy said the actions followed maritime patrol and surveillance and formed part of ongoing maritime, aerial and land operations intended to inhibit illicit activity in Mexican waters. It reported more than 97 tonnes of cocaine seized at sea during the current administration before adding these packages. The statement said the new seizure would be included once the ministerial weight is determined.
