The statement says, in part:
"The U.S. Embassy has conducted a thorough review of current information surrounding the potential kidnapping threat against U.S. citizens in the Cusco and Machu Picchu area by members of a criminal organization. Based upon this review, the February 13 restriction on travel by U.S. Embassy personnel to the region has been lifted."
The kidnapping scare, kicked off by the mother of an American cyclist who'd stopped updating his Facebook feed while in Peru, rippled through the country's travel and hospitality industries. Garrett Hand, the "missing" cyclist, has since been in touch with his mom.
The embassy still has some suggestions for American travelers like signing up for the Department of State's Smart Traveler Enrollment Program and avoiding certain regions known for crime. We'd add another suggestion to the list: Call your mother.
