CANCÚN: Gunfire broke out on a posh beach in Mexico’s Caribbean coast resort of Cancún on Tuesday (Wednesday in Manila), sending tourists scrambling for cover, but authorities said nobody appeared to be injured. Lucio Hernández Gutiérrez, the chief of police of the coastal state of Quintana Roo, said the attackers apparently pulled up to the beach on jet skis and opened fire at a beach in Cancún’s hotel zone. Hernández Gutiérrez said the jet skis had been found and seized. One witness to the attack, Rick Lebassa, a tourist from Maine, said two or three gunmen appeared to be shooting into the air with pistols, not at the beach.
