Gunmen stormed a beer hall in northern Mexico, killing 10 people in broad daylight in a suburb of the industrial city of Monterrey before stripping the bodies. Several armed men arrived in two vehicles before attacking people inside the bar in the municipality of Garcia at around 3pm on Friday, an official in the state prosecutor's office said. The assailants stripped seven bodies naked and left with 10,000 pesos (HK$5,050) in cash, the Nuevo Leon state official added. "Seven died at the scene of the attack and three more [succumbed to their wounds] in a hospital," said state security spokesman Jorge Domene. The motive of the shooting was not immediately known. Garcia is the hometown of Jaime "El Bronco" Rodriguez, the former mayor who made international headlines on June 7 when he became the first independent candidate to win a gubernatorial election in Mexico. The Nuevo Leon governor-elect gained fame when he was mayor from 2009 to 2012 as he defied the violent Zetas drug cartel. Rodriguez said he survived two assassination attempts when he was mayor and that his daughter was briefly kidnapped when she was two years old. Zetas leader Omar Trevino was captured in March in another Monterrey suburb. The Zetas are accused of being behind an arson attack against a Monterrey casino that left 52 people dead in 2010.
