Naval forces in Mexico and El Salvador announced major cocaine seizures this week totaling more than 10 tonnes, highlighting a sharp contrast with recent U.S. military strikes in Latin American waters that left 11 people dead.

Mexico’s government said authorities intercepted a semi-submersible vessel roughly 250 nautical miles south of Manzanillo, seizing nearly four tonnes of suspected cocaine and detaining three people. Security Secretary Omar García Harfuch noted the operation brought Mexico’s weekly total close to 10 tonnes, though additional details were not disclosed. Officials said intelligence from U.S. Northern Command and the Joint Interagency Task Force South supported the mission.

Meanwhile, El Salvador’s navy reported the largest drug seizure in its history: 6.6 tonnes of cocaine found aboard a Tanzania-flagged vessel intercepted far off its Pacific coast. Divers located hundreds of packages hidden in ballast tanks, and 10 men from Colombia, Nicaragua, Panama and Ecuador were arrested.

The seizures come as the U.S. continues controversial military strikes against suspected drug-trafficking boats in the Caribbean and Pacific, operations that have resulted in at least 145 deaths since last September. Critics question the lack of publicly presented evidence linking all targeted vessels to narcotics trafficking.
