Mass grave found in Cambodian village

Skulls and bones mark a mass grave found in a Siem Reap village.

Authorities believe there are hundreds buried here and that they are among the millions murdered during the Khmer Rouge's bloody, five-year reign in the 1970s.

Villagers came to the site to offer prayers for lost family members.

(SOUNDBITE) (Khmer) 47-YEAR-OLD RESIDENT, CHEA NGEK SAYING:

"I come to pray here because I do not know where my sister and her family were killed. They may be buried here so I am praying to them."

The discovery was made on June 30 by a driver, who said the bones were buried five metres deep in the soil.

The Khmer Rouge's "Year Zero" revolution wiped out a quarter of the country's population.
