Relatives offer crosses in tribute to victims in Monterrey August 18, 2012. Family members and friends gathered to commemorate the 54 victims who died in August 25, 2011 after gunmen of the Zetas drug cartel attacked the Casino Royale in Nuevo Leon's capital Monterrey, a wealthy city that increasingly has fallen prey to the ravages of drug cartels, local media reported. The relatives placed the crosses representing their loved ones outside the casino a week before the anniversary of the arson attack. REUTERS/Daniel Becerril (MEXICO - Tags: CIVIL UNREST CRIME LAW)
