A rocket-propelled grenade believed to be more than 25 years old killed two 2-year-old cousins in rural northwestern Cambodia. The toddlers apparently came across the unexploded ordinance near their homes and it detonated. Cambodia has been heavily affected by land mines and unexploded munitions from decades of conflict, with nearly 20,000 people killed and about 45,000 injured since the end of the fighting. Cambodia's demining efforts recently faced a setback when U.S. financial assistance was suspended, but it has since been allowed to resume.
