A faction of the Sinaloa Cartel threatened to attack government buildings in Mexicali following a major narcotics seizure and several arrests.

The threats signal an escalation in violence between organized crime and federal authorities in Baja California, specifically targeting the legal and security infrastructure of the region.

The group known as "Los Rusos" issued warnings of attacks, potentially involving explosives, against two specific locations [1]. These include the Federal Prosecutor's Office building and the public security directorate in Mexicali [1].

Federal prosecutors and local police said the threats are a direct retaliation for a recent security operation. During that operation, authorities seized 120 kilograms of fentanyl [2]. The crackdown also resulted in the capture of 46 cartel members [2].

Security secretary General Laureano Carrillo Rodríguez has been involved in the response to these threats. The government has heightened security operations in the area to protect officials and prevent the promised attacks.

The "Los Rusos" faction is a known branch of the broader Sinaloa Cartel. The group is now targeting the Fiscalía General de la República and municipal police forces after the loss of personnel and narcotics [3].

Local authorities in Mexicali continue to monitor the situation as the risk of explosive devices remains a primary concern for the public security directorate [1].

This incident underscores the volatile relationship between the Mexican state and the Sinaloa Cartel's fragmented factions. By specifically targeting the Federal Prosecutor's Office and police directorates, Los Rusos are attempting to intimidate the judicial process and deter future enforcement actions. The use of fentanyl as a primary commodity highlights the continued centrality of synthetic opioids in the cartel's economic structure and the high stakes of its interdiction.
