Fatal crashes and gunfire
Four of the deaths occurred near Soliseño on the Matamoros-Reynosa highway, where a family of five in a car struck a burning bus positioned as a roadblock. The surviving occupant, a child with serious injuries, was hospitalized at a Mexican Social Security Institute facility.
In the rural community of Las Rusias, a bullet killed a seven-year-old girl. Another motorist died in a collision with a cargo vehicle blocking the road to the Los Indios International Bridge.
The six-death tally followed an initial report from the Tamaulipas Security Spokesperson's Office, which cited the state prosecutor's office in confirming one minor's death and injuries to two people. Authorities announced investigations into the incidents.
Trucks and passenger vehicles obstructed avenues and highways in Matamoros and Río Bravo after the arrest, with some vehicles set ablaze. Incident reports also described disruptions on highway stretches in San Fernando and Valle Hermoso.
The roadblocks extended to kilometer 45 of the Victoria-Matamoros highway near the Padilla bridge and to roads toward Reynosa and Nuevo Progreso. Tire spikes were also reported. The fires, obstructions and gunfire halted traffic on major routes and interrupted public transportation.
Military operation and road clearance
On Friday, federal authorities sent 450 soldiers and two helicopters to increase surveillance in Matamoros and the surrounding area. President Claudia Sheinbaum said the Secretariat of National Defense and the National Guard had launched a special operation to clear blocked roads and address criminal groups' reactions to arrests of high-priority targets.
"It was the arrest of a violence-generating figure," Sheinbaum said at her morning news conference. She said federal forces had tow trucks and procedures for removing vehicles used to obstruct highways, and that the Security Cabinet would release further details.
State authorities said the roadblocks had been cleared, while federal forces and local agencies continued joint patrols. Matamoros Mayor José Alberto Granados Fávila said Friday morning that the city's main routes were open and no roadblocks remained. Municipal crews helped remove vehicles left abandoned or damaged.
Who was arrested
Federal authorities identified Cárdenas Rodríguez, known as "Axel" or "El Titán," as the second-in-command of Los Ciclones, a faction linked to the Gulf Cartel. Army special forces and the National Guard carried out the Matamoros operation with military intelligence support. Mexico's Registro Nacional de Detenciones recorded the arrest at approximately 11:00 a.m. local time on October 29.
Security and Citizen Protection Secretary Omar García Harfuch confirmed that Cárdenas Rodríguez and a second person had been detained. He reported the seizure of a vehicle, weapons, magazines, ammunition and drugs. The Mexican Air Force transported both detainees to Mexico City, where they were turned over to federal authorities.
Social media images showed Cárdenas Rodríguez beside a blue Lamborghini Urus on Pedro Cárdenas Avenue in Matamoros. He was reportedly driving that vehicle; authorities said they seized a vehicle but did not identify it in the account of the operation.
Harfuch also publicly accused Cárdenas Rodríguez of responsibility for an armed attack on May 17, 2026, in Matamoros' La Encantada neighborhood. The attack targeted Servicio de Protección Federal officers assigned to guard the U.S. Consulate, killing officer Marcelo Vázquez Vázquez and wounding two others.
This was Cárdenas Rodríguez's second arrest. Authorities first detained him in Matamoros on May 7, 2023, alongside his brother Alen, also identified as Alan, Alexis Cárdenas Rodríguez. A judge granted Axel provisional release on January 18, 2024.
His father is José Alfredo Cárdenas Martínez, known as "El Contador," whom Mexican and U.S. authorities identify as a Los Ciclones leader. Axel is also a nephew of former Gulf Cartel leader Osiel Cárdenas Guillén, who is imprisoned at the Altiplano federal prison.
Los Ciclones operates around Matamoros and is described as one of the Gulf Cartel's two strongest factions. It is allied with Los Escorpiones; both groups emerged from the fragmentation of Los Zetas.
The elder Cárdenas was arrested in Mexico City in February 2022 and released by a federal judge in November 2024. The United States sought his extradition, which Mexico's Foreign Ministry approved in December 2024.
Transit resumes after school and border disruptions
Public transportation stopped for several hours during Thursday's violence because of unsafe road conditions. Five city buses burned and were declared total losses, while employee and school transportation vehicles were also affected. The Tamaulipas Education Secretariat suspended afternoon classes as a precaution.
By Friday, all 16 urban bus routes were operating again, according to the state transportation delegation, with about 380 vehicles available to passengers.
The disruption also affected crossings between Matamoros and Brownsville, Texas. Brownsville police announced temporary closures of international bridges during the incidents and later said the crossings had reopened.
The U.S. Consulate in Matamoros instructed its personnel to shelter in place amid police activity and closures on major roads and at key intersections. The U.S. State Department reiterated that Tamaulipas remained under a Level 4 travel advisory, advising against all travel because of crime, terrorism and kidnapping risks.
The Tamaulipas Attorney General's Office continues to investigate the deaths, injuries and property damage from the roadblocks.
