Gunmen ambush police convoy near Mexico City, killing 13

The massacre of the 13 law enforcement officers in the State of Mexico on Thursday was the country's single biggest slaying of law enforcement since October 2019, when cartel gunmen ambushed and killed 14 state police officers in the neighbouring state of Michoacan. 

The ambush sparked a huge search for the killers in a rural, gang-plagued area southwest of Mexico City, which is surrounded on three sides by Mexico State. The dead law enforcement officers worked for the state. 

While Mexico State contains suburbs of the capital, it also includes lawless mountain and scrub lands like the one where the attack occurred. 

Rodrigo Martínez Celis, the head of the state Public Safety Department, said soldiers, marines and National Guard troops were combing the area by land and from the air looking for the killers. 

“The convoy was carrying out patrols in the region, precisely to fight the criminal groups that operate in the area,” Martínez Celis said. "This aggression is an attack on the Mexican government. 

“We will respond with all force,” he added. 

There was no immediate indication as to what gang or cartel the gunmen might have belonged to. Several operate in the area around Coatepec Harinas, where the attack occurred. 

The town is near a hot springs resort known as Ixtapan de la Sal, which is popular among Mexico City residents as a weekend getaway. But it also relatively close to cities like Taxco, where authorities have reported activities by the Guerreros Unidos gang apparently allied with the Jalisco cartel and by the Arcelia gang, dominated by the Familia Michoacán crime organization. 

The attack appears to present a challenge for President Andrés Manuel López Obrador, who has pursued a strategy of not directly confronting drug cartels in an effort to avoid violence.
