On April 6, 2015, a convoy of the Jalisco State Police was ambushed by suspected members of the Jalisco New Generation Cartel (CJNG), a criminal group based in Jalisco.
 The attack occurred in a mountain road in San Sebastián del Oeste, Jalisco.
 Fifteen policemen were killed and five were wounded; no CJNG casualties were confirmed.
 According to police reports, as the police convoy reached a part of the road surrounded by mountains, the CJNG opened fire at the police units from the sides using high-caliber rifles, grenade launchers, and explosives with gasoline.
 The element of surprise prevented the police from repelling the aggression.
 The CJNG members burned several vehicles along the highway to halt reinforcements.
 The attack lasted roughly 30 minutes.
 When government reinforcements reached the scene, the CJNG gunmen had left.
Abigael González Valencia (born October 18, 1972), commonly referred to by his alias El Cuini, is a suspected Mexican drug lord and former leader of the Jalisco New Generation Cartel (CJNG), a criminal group based in Jalisco.
 He was also the head of Los Cuinis, an organization allied to the CJNG.
 Along with his brother-in-law Nemesio Oseguera Cervantes (alias "El Mencho"), one of Mexico's most-wanted men, González Valencia reportedly coordinated international drug trafficking operations in the Americas, Europe, and Asia.
 He was also responsible for managing the financial operations of the CJNG and Los Cuinis.

 The CJNG are currently fighting the Knights Templar Cartel and Los Zetas for control of the cities of Guadalajara, Jalisco and the states of Michoacán and Veracruz.
 The CJNG also operates in the states of Nayarit, Colima, and Guanajuato.

Yang Su (楊素) (died August 31, 606), courtesy name Chudao (處道), formally Duke Jingwu of Chu (楚景武公), was a powerful general of the Sui dynasty whose authority eventually became nearly as supreme as the emperor's.
 Traditional historians generally believed that he was involved in the suspected murder of Emperor Wen in 604, at the behest of Emperor Wen's son Yang Guang (the later Emperor Yang).
 His son Yang Xuangan later rebelled against Emperor Yang in 613 but was defeated and killed, and Yang Su's other sons were also executed.
The Federal Police (Spanish: "Policía Federal, PF" ), formerly known as the "Policía Federal Preventiva" (Federal Preventive Police), is a Mexican police force under the authority of the Secretariat of the Interior.

On May 22, 2015, a three-hour shootout broke out between the Mexican Federal Police and alleged members of the Jalisco New Generation Cartel (CJNG) in Tanhuato and Ecuandureo, Michoacán, leaving 43 dead.
 One of the fatalities was a Federal Police officer, while the others were suspected to be organized crime members.
 The confrontation started when the Federal Police spotted a suspicious vehicle on a highway.
 The authorities had received information that one of the properties in the area had been overrun by criminals.
 Unconfirmed reports suggested that the CJNG leader Nemesio Oseguera Cervantes was in the area.
 When they tried to pull over the vehicle, however, the men onboard opened fire at the police units.
 A vehicle chase ensued and the security forces made their way into a large, rural property where the shootout intensified.
 The Federal Police then called for ground and air reinforcements and neutralized the situation.

On 1 July 2010, members of two rival cartels clashed near the village of Sáric, in Mexico's northwestern state of Sonora, approximately 12 miles southeast of the little-used port of entry in Sasabe, Arizona.
 Local news media and officials in the Mexican government reported that the violence was the result of an ambush, organized by a group aligned with the Beltrán-Leyva Cartel to stop a convoy of over 50 vehicles of the Sinaloa Cartel from entering Saric.
 The Beltrán-Leyva group took up positions on a hill along the road outside of Saric, and as the convoy approached, laid down a devastating barrage of fire into the convoy below.
 Shortly after the fighting ended, Mexican police and military arrived to find the bodies of 21 dead and several bullet-strewn vehicles, mostly SUVs. Nine men were taken into police custody, six of whom received wounds in the shootout.
