Peru takes dim view of nude tourism at Machu Picchu, the Inca ruins
Authorities increase surveillance at Machu Picchu, a popular spot for naked travel photos
Peru has increased surveillance at popular archaeological sites to counter a new trend of tourists taking nude photos at the Machu Picchu Inca ruins.
Tourists have been posting the naked pictures on blogs, prompting a statement from the cultural ministry rejecting "any disrespectful act committed by visitors" to the sites.
"We have redoubled efforts for continuous surveillance and monitoring of the site", so security personnel could intervene to stop the exhibitionist photography, it said.
The ministry called on visitors to help protect the historical sites and to "be alert to this kind of attitude, that's solely aimed at getting attention".
Authorities are also worried over a recent spate of graffiti attacks.
Last week, the famous 12-Angle Stone - an example of intricate Incan masonry and design - was hit with spray paint, police said. The suspect had been involved in several other attacks on archaeological sites, they added.
