The first clash occurred shortly after sunset Wednesday when soldiers responding to a report of a pipeline tap were ambushed by gunmen who used women and children as human shields, the defense ministry said in a statement. Two soldiers were killed but the troops withdrew without returning fire to avoid harming the civilians, the ministry said.

Hundreds of soldiers and federal police returned to Palmarito a few hours later, engaging gunmen in a clash that left two more soldiers and six suspected gunmen dead, officials said. Security forces recovered armored vehicles, several rifles and other weapons.

Palmarito lies within the so-called Red Triangle, which officials have cited as one of the primary areas for theft from fuel pipelines that link refineries to central Mexico.
