MEXICO CITY (Reuters) - Shootouts in the western Mexican state of Sinaloa have kindled fears that an intra-cartel war is about to break out in the wake of the arrest of legendary trafficker, Ismael "El Mayo" Zambada, in July.
One soldier and two civilians were killed on Monday, authorities say. Videos widely shared online showed heavily armed gunmen moving on foot or riding trucks in areas around Culiacan, the state capital, while gunfire echoes in the background. Many cars and business have been shot at.
Calm had returned by Tuesday morning, though some shops had closed at midday.
Analysts have predicted a war within the Sinaloa Cartel ever since Zambada's arrest on July 25. The veteran cartel leader, believed to be in his mid-70s, alleges that a senior member of the Los Chapitos, another faction of the cartel, kidnapped him and then flew him to the United States against his will.
El Mayo and Los Chapitos, a grouping led by the sons of ex-Sinaloa Cartel kingpin Joaquin "El Chapo" Guzman, are widely believed to lead the two most powerful factions in the powerful crime syndicate.
One Sinaloa-based security official told Reuters fighters from the Los Chapitos faction entered areas controlled by Zambada to intimidate them. Some media reports, however, suggested that it was fighters loyal to Zambada who attacked Los Chapitos’ faction.
"It is believed that there may be more fighting and that these clashes are between the same two groups (within the cartel)," said America Armenta, an independent Sinaloan journalist in Culiacan.
Mexican authorities sent another 90 special forces soldiers to Sinaloa on Tuesday, taking the number of elite troops dispatched to the state since Zambada's arrest to nearly 600.
Mexican President Andres Manuel Lopez Obrador said the government is "watching and taking action" to ensure calm.
"It's a confrontation, and I hope it's temporary," Lopez Obrador said in his daily press conference on Tuesday.
