Mexican authorities say more than fifty people have been found dead inside a casino in the northern city of Monterrey, the capital city of Nuevo Leon, that was set on fire by armed assailants on Thursday. The Attorney General for Nuevo Leon state, Adrian de la Garza, told reporters that more bodies could be found as the crew dig through the burned out rubble of the Casino Royale. Witnesses say several gunmen burst into the casino and doused the premises with gasoline before setting it on fire. Mexican President Felipe Calderon condemned the attack as an abhorrent and barbaric act of terror in a message on Twitter.
