Members of the Federeal Police check a van suspected of having explosives, in Ciudad Juarez
The Christmas holiday weekend failed to stem the violence in Mexico's murder capital Ciudad Juarez, where drug-related shootings have killed 13 people over two days, officials said Saturday.
Eleven of the murder victims were shot Friday, while two more were killed on Christmas Day, authorities for the northern Mexican state of Chihuahua said.
More than 12,000 murders have been committed this year as part of Mexico's vicious four-year drug gang war, with 30,000 deaths in all since President Felipe Calderon launched a massive military crackdown on the cartels, according to figures released this month.
Security officials said they have arrested more than 27,000 suspected drug gang members as part of the ongoing crackdown, including at least 17,000 detained this year.
