Nueva Italia (Mexico) (AFP) - Vigilantes seized a drug cartel's bastion in western Mexico on Sunday, sparking a shootout as the civilian militia gained new ground in their struggle against the gang in a violence-plagued region.

Hundreds of armed civilians riding in more than 100 pickup trucks rolled into the Michoacan state town of Nueva Italia and were met by gunfire from presumed Knights Templar cartel members when they reached the municipal office.

"They shot at us from two locations and the clash lasted around an hour and a half," Jaime Ortiz, a 47-year-old farmer and vigilante leader from the town of La Ruana, told AFP.

Two members of the self-defense unit were wounded, he said, standing in the 40,000-population town's main square, surrounded by hundreds of men armed with AK-47 assault rifles, bulletproof vests and radios.

Some sidewalks were soaked in blood in the town's empty streets.

Later, on a highway leading to the town, authorities found two men hanging from a bridge, though it was not immediately known if the killings were related to the vigilantes' advance. Mexican cartels have hanged many victims in recent years.

Michoacan's growing civilian militia movement, which first emerged nearly a year ago, has seized more communities in recent weeks in its bid to rout the Templars.

The turmoil in Michoacan has become the biggest security challenge of President Enrique Pena Nieto's 13-month-old administration, which inherited a drug war that has killed more than 77,000 people in the past seven years.

Pena Nieto deployed thousands of troops and federal police to the state in May, but the reinforcements have failed to contain the violence.

Interior Minister Miguel Osorio Chong has said the self-defense units are illegal. Yet some critics charge the government is protecting them.

The Templars have accused the vigilantes of being a proxy force for the rival Jalisco New Generation drug cartel, a charge the militias deny.

The militias have now surrounded Apatzingan, a city of 123,000 people considered the main Templar stronghold in Michoacan's lime- and avocado-growing region known as Tierra Caliente, or Hot Country.

Vigilante leaders say Apatzingan is a key target because of its importance to the cartel and because it is a vital trade hub for their limes, avocados and mangos.

In October, hundreds of self-defense militia members marched into Apatzingan unarmed and fled after being welcomed with gun shots in the main square. Read on at Source

"It is very close. We want to seize it but we don't have a date yet. It will be in the next few days," said Hipolito Mora, a prominent vigilante leader from the town of La Ruana.
