About 3,500 acres of southern Arizona have been closed off to U.S. citizens due to increased violence at the U.S.-Mexico border, according to the U.S. Fish and Wildlife Service. U.S. Fish and Wildlife officials have warned visitors in Arizona to beware of heavily armed drug smugglers and human traffickers.
