Mexico: Major security operation reported in Matamoros following 'armed incidents' March 3

Event

Authorities have launched a major security operation in Matamoros, Tamaulipas State, as of March 3 following what officials from Tamaulipas' Secretariat of Public Security described as "armed incidents between unidentified civilians." The incidents have resulted in an unspecified number of deaths and injuries. As part of the operation, both police and military forces have deployed throughout the city. Authorities have recommended that all persons in the area remain in their homes during the operation.

During the operation, security forces are likely to set up checkpoints on roads and highways in and near the city, causing transport disruptions. Many businesses in the area are likely to close. Additional armed clashes cannot be ruled out.

Context

While the government has not announced who was responsible for the clashes, Matamoros is home to various rival factions of the Gulf Cartel (Cartel del Golfo) and is part of a major drug-smuggling route; drug-trafficking organizations are, therefore, almost certainly responsible for the violence.

Advice

If operating in Matamoros, shelter in place until authorities give the all-clear and the security operation ends. Seek alternative routes that avoid Matamoros if operating elsewhere in Tamaulipas State and allow for additional transport time. Heed the instructions of security personnel.
