37 cartel gunman die in failed ambush of Mexican army?

Guardian:

Dozens of people are reported to have been killed in a fierce gun battle after federal forces came under attack in a region of western Mexico dominated by drug cartels.

Officials said that a convoy of federal police and soldiers were ambushed near the border of Michoacán and Jalisco states.

Two government sources told the Reuters news agency that 37 armed civilians – presumably cartel gunmen – were killed in the confrontation. At least two police officers were also reported to have died.

The identity of the gunmen was not known, but the area between Michoacán and Jalisco is known as a stronghold of the Jalisco New Generation cartel, which has mounted several large-scale attacks on federal and state forces in recent weeks.

This looks like an ambush that went wrong.  I suspect the military had automatic weapons although in Mexico, both sides could have had them.  The drug wars seem far from over in Mexico.
