MEXICO CITY - Security forces in the state of Sinaloa reported on Monday that 10 assailants were killed and three individuals were arrested following an attack on navy personnel who were carrying out flood-monitoring duties over the weekend.
The navy said the fatal outcome for the attackers occurred after security forces repelled a second assault in the municipality of El Rosario. The statement noted that naval teams had been performing monitoring of rivers and dams to detect sudden rises in water levels and to provide warnings to communities ahead of the rainy season when they were ambushed.
In the initial attack, three sailors were wounded. Authorities later reported that one of those sailors died, while the other two are out of danger. The navy indicated that the three detained suspects were handed over to prosecutors so that a formal investigation could be opened.
The operation unfolded while state security authorities were undergoing a major reinforcement, according to the navy's statement. The account provided by the navy did not offer additional detail on the identities or affiliations of the assailants, nor did it supply further operational specifics beyond the sequence of the ambush, the second assault, the casualties, and the transfer of detainees to prosecutors.
The naval personnel involved had been engaged in activities intended to track water levels at rivers and dams and to alert nearby communities if sudden increases were detected. That monitoring was taking place in advance of the seasonal rains, the navy said, when the patrol was ambushed.
Authorities have moved the three suspects into the formal justice process by delivering them to prosecutors, who will carry out an investigation based on the evidence and circumstances gathered by security forces. Beyond the details already stated by the navy, the public statement did not expand on next steps for the flood-monitoring program, nor on whether additional arrests or operations are ongoing.
Context and next steps
The navy's summary of the incident centers on the protection of monitoring teams, the immediate tactical response that left 10 attackers dead after a second assault was pushed back, and the handover of three detainees to prosecutors. The broader reinforcement of state security under which the operation took place was also noted in the navy's statement.
