At least five foreign visitors have been arrested and deported this year for taking nude photos at Cambodia's most popular tourist attraction, the sacred complex of temples that includes the Angkor Wat.

Authorities have no tolerance for people stripping down at Angkor Archeological Park, a sprawling, centuries-old UNESCO World Heritage Site that drew 2 million visitors in 2014. The incidents are also upsetting to ordinary Cambodians, for whom the complex holds spiritual and historical significance.

"Angkor Wat is the most sacred temple in Cambodia. Not only Cambodians but also tourists have to pay respect," said Rattanak Te, a resident in Phnom Penh, the capital.
