Thousands of unexploded ordnance pieces found beneath Cambodian school grounds

Over 2,000 pieces of unexploded ordnance, such as grenades and shells, were collected over the weekend after authorities found the ammunition buried at a high school in Cambodia.

The site was an ammunition warehouse during the Khmer Rouge regime in the 1970s before being turned into a school and all of the ordnance was thought to have been removed, Chheang Heng said.
