MEXICO CITY – Suspected drug hitmen stormed a private party and killed 17 people in the northern Mexican city of Torreon on Sunday in one of the deadliest attacks in Mexico's drug war.
Gunmen in five SUVs drove up to the party in a walled patio and garden on the outskirts of the city in Coahuila state across from Texas, smashed down the door and opened fire with automatic rifles on party-goers at about 1 am/0500 GMT, Coahuila's prosecutor's office said.
Photos showed blood-stained floor tiles, overturned chairs and musical instruments by a beer tent abandoned as people ran in panic.
The attack underscored the challenges facing President Felipe Calderon's new interior minister, who took up his job this week facing criticism that he lacked experience to deal with drug cartels.
The prosecutor's office in Coahuila said 18 people were injured in the attack and taken to hospital. The party garden was strewn with more than 100 bullet casings, it said in its statement. No arrests have been made.
Mexico's attorney general's office immediately took over the investigation into the killings, Mexican daily Reforma said.
The early morning attack comes days after a drug gang detonated a car bomb in Ciudad Juarez late on Thursday, killing four people in the first attack of its kind in Mexico's drug war.
Ciudad Juarez's main daily El Diario reported on Sunday that US agents from the Federal Bureau of Investigation and the Bureau of Alcohol, Tobacco, Firearms and Explosives were in the city to investigate the car bomb attack. US and Mexican officials declined to comment.
Federal police blamed La Linea, the armed wing of the powerful Juarez cartel, for the car bomb and Mexico's security ministry said it was retaliation for the arrest this week of a cartel member.
In Torreon, it was not immediately clear who was responsible for the attack but the area, a key transit point along smuggling routes into the United States, is being fought over by the Sinaloa cartel led by Mexico's most-wanted man, Joaquin "Shorty" Guzman, and the Zetas gang from northeastern Mexico.
Once quiet northern industrial cities such as Torreon and nearby Monterrey have seen a surge in drug killings in the past six months as the Zetas fight the Sinaloans and the Gulf cartel that controls much of the smuggling routes into Texas.
More than 26,000 people have been killed in drug violence across Mexico since Calderon took office and started a crackdown on drug cartels in 2006. Escalating violence is worrying Washington and investors in the oil-producing country once known for its political stability next door to the United States.
