Officials in Cambodia say a rocket-propelled grenade believed to be more than 25 years old has detonated and killed two cousins, a girl and a boy both 2 years old.

Two Cambodian toddlers died when a rocket-propelled grenade believed buried since the country's civil war blew up near their homes, an official said on Sunday (Feb 23).

A rocket-propelled grenade believed to be more than 25 years old killed two cousins, a girl and a boy both 2 years old, when it blew up Saturday near their homes in rural northwestern Cambodia, officials said.

The tragedy, over 25 years after the civil war ended, came after the nation had to partially suspend demining operations when the US halted funding.
