Children react to a piece of human bones shown by their mother at a grave site of Phnom Trungbat in Do Dontrei village, about 60 kilometers (40 miles) northwest of Siem Reap in Cambodia, Thursday, Aug. 9, 2012. More than 100 people attended a Buddhist ceremony in rural Cambodia at the site of a freshly dug Khmer Rouge mass grave. Buddhist monks led prayers and people came with offerings of food and drinks Thursday, five days after about 20 skulls and bone fragments were unearthed at the site of a former Khmer Rouge prison.
