A woman cries as she looks at skulls and bones of more than 8,000 victims of the Khmer Rouge regime during a Buddhist ceremony at Choeung Ek, a "Killing Fields" site located on the outskirts of Phnom Penh, April 17, 2015. Hundreds of Cambodians and monks gathered at the site to commemorate the 40th anniversary of the Khmer Rouge reign, which plunged the nation into a radical communist group genocide regime from 1975-1979.
