People stand near a destroyed area after an explosion at a hotel in Cancun November 14, 2010. At least six people, including four Canadian tourists and two Mexican workers, were killed in an explosion at a resort on Mexico’s Riviera Maya, a Mexican official said, in what authorities described as a gas explosion. Another 15 to 20 people were wounded from the blast at the Grand Riviera Princess hotel in the beach resort of Playa del Carmen on Mexico’s Caribbean coast, Francisco Alor, the attorney general for the surrounding Quintana Roo state, told Reuters.
