Inside the 'cold war' taking place within the Sinaloa Cartel since the capture of 'El Mayo' Zambada

Tensions are escalating in Sinaloa as factions of the eponymous, historically linked but now divided, appear to be heading towards increased conflict.

The arrest of Ismael "El Mayo" Zambada, co-founder of the cartel and still one of its most relevant figures, has intensified the rivalry between two groups: the "Mayiza," loyal to Zambada, and the "Chapitos," led by the sons of Joaquín "El Chapo" Guzmán. This division has heightened security concerns and sparked fears of violence in Culiacán, the cartel's stronghold, according to a new analysis by specialized outlet InSight Crime.

To illustrate the rising tensions, the outlet described the ongoing situation in the town of La Loma. With just over a thousand residents, it lies near Federal Highway 15D, an area considered a border between territories controlled by the Mayiza and Chapitos. Following Zambada's capture, speculation has grown that he was betrayed by Chapitos member Joaquín Guzmán López, further straining relations between the factions.

The arrest has led to an increased military presence in Sinaloa, with about 1,000 soldiers deployed to maintain order. Reports of violence are already emerging; on August 17, seven people were killed in Elota, including several Mayiza operatives. Earlier, on August 2, six individuals were killed in La Loma during an alleged confrontation with the army, raising concerns among residents who fear further escalation.

The division between the Chapitos and the Mayiza has also extended into the prison system, where inmates are now more concerned about having to choose sides. The Chapitos' alleged betrayal is seen as a significant breach of cartel codes, and while violence has not yet exploded, the potential for conflict looms large.

El Mayo's capture has left his son, Ismael "Mayito Flaco" Zambada, in charge of the Mayiza. However, sources suggest that he may be avoiding direct retaliation to keep a low profile and government scrutiny. Despite this, the tension in border communities like La Loma continues to rise, with residents and cartel members alike preparing for the possibility of violence.

The situation near the U.S. border in Sonora and Baja California has already seen ongoing proxy conflicts between the factions. These battles, primarily over control of drug trafficking routes, have intensified since El Mayo's capture. Despite the internal cartel conflicts, the flow of drugs, particularly synthetic drugs like fentanyl and methamphetamine, continues largely uninterrupted, indicating the resilience and decentralization of the drug trade.
