A good start.
MEXICO CITY (AP) — Mexican marines battled alleged members of the Zetas drug cartel for more than five hours in northern Mexico on Friday, leaving 15 gang suspects dead and six marines wounded, authorities said.
The troops were on patrol in the town of San Jose de Lourdes in northern Zacatecas state when they came under fire from gunmen inside a safehouse, Mexico's navy said in a statement. It said 17 gunmen were detained.
The Zetas drug cartel began expanding into Zacatecas from the border state of Tamaulipas two years ago after it split from the Gulf cartel.
