Mexico City: A gang ambushed a federal police convoy in western Mexico, sparking a shootout that killed five officers, three suspects and two bystanders, authorities said Friday.
The attack took place late Thursday as the seven vehicles carrying paramilitary gendarmerie officers were on patrol in Ocotlan, Jalisco state, the federal police said in a statement.
Eight other officers were wounded, including one in serious condition.
It was the deadliest shooting for Mexico`s new gendarmerie, a 5,000-strong unit modeled after European military-like forces that President Enrique Pena Nieto launched last year to protect key economic sectors from organized crime.
"We have regrettably had minor losses of one officer in some other events," but never so many in one attack, a federal official told AFP. A gendarmerie commander deployed in Jalisco said the officers were checking on reports of an attack on municipal police when they were ambushed.
The police statement said the officers were on patrol at around 9:15 pm when a vehicle approached the convoy and "without uttering a word, one of the individuals pulled out a large weapon and shot at the federal agents."
The officers shot back and more gunmen arrived in about 10 other vehicles, firing in all directions.
The gendarmerie commander said the shootout lasted 30 minutes and took place in several streets.
"As a result of this clash, we report the deaths of five gendarmerie division officers and three civilians whose bodies had cartridge belts and tactical equipment and who presumably are part of organized crime," the statement said.
"We regret the death of two civilians," it added. The bodies were in the same firing line as the officers.
The statement did not say what criminal organization the suspects belong to, but the region is home to the Jalisco New Generation drug cartel.
The suspects kept shooting as they fled the scene, leaving bullet holes in several vehicles parked in several neighboring streets.
Authorities found seven "large weapons" -- a term usually referring to assault rifles -- and four grenades. The suspects left behind five vehicles.
The federal attorney general`s office will investigate the attack. More than 100,000 people have died or gone missing since Mexico`s drug war began to escalate in 2006 with the deployment of troops to combat drug cartels.
Criminals have attacked authorities in Jalisco in recent years.
In October, a federal lawmaker was abducted on a highway as he drove to the airport near Guadalajara, Mexico`s second biggest city. His charred body was found hours later in a neighboring state.
In May 2014, a group of 30 gunmen armed with grenades ambushed a military truck near the Jalisco town of Guachinango. Four soldiers were killed after the assailants tossed their grenades, sparking a shootout.
