Tourist shot in leg at Mexican resort near Cancun.

A U.S. tourist was shot in the leg by unidentified assailants in Puerto Morelos, a resort town south of Cancun. The motive remains under investigation. The U.S. State Department issued a travel alert this month warning travelers to "exercise increased caution," especially after dark, at Mexico's Caribbean beach resorts like Cancun, Playa del Carmen, and Tulum, which have been plagued by drug gang violence in the past.
