One of the most horrible tragedies this is Cambodian genocide mass graves prison s21 Phnom Penh. Cambodia the killing fields.
Everywhere the signs of war are still visible and the terrible wounds of the terrifying genocide between the years 1975 and 1979. The specter of the Khmer Rouge still evoke in the minds of Cambodians the years of the death.
Despite the horror, nobody seems to be intentioned to forget the hugeness of the cruelties suffered during war time and many old people still show the photographs of their relatives tortured and killed by Khmer Rouge. Due the consequences of the genocide that caused the massacre of two millions people, this is a very young country and the middle age does not exceed 35/40 years.
Unfortunately, the ghosts of war are not definitively disappeared. Many Khmer rouge rebels and Pol Pot’s followers are still hidden in the forests close to the Thailand border. My advice is: keep far from this area!
If you have planned to go to Cambodia, before the departure you should collect all the necessary information about the current political situation. The best information resourse is of course the embassy or the consulate based in your country.
They will give you all the updated and detailed info on how to move through the country. You should know that is not easy to move through Cambodia without a local guide. Many sites, many rural lands and some streets are still mined and every year many children remain wounded by unexploded mines hidden in the grass. You must be very careful and you should pay attention to security advices that inform people to keep far from some unexplored streets.
