The clashes follow a daring march over the weekend by self-defence force vigilantes into the city of Apatzingan, the central stronghold of the Knights Templar.
In retaliation, gunmen believed to be linked to the pseudo-religious cartel mounted coordinated attacks on electrical facilities in 14 towns and cities throughout Michoacan yesterday.
Vigilante leader Jose Mireles said today the retaliation also included an armed attack on self-defence trenches on the outskirts of Michoacan. Detectives say five men were found dead at the scene, but Mireles says there 13 deaths.
