A mortar shell left from the Vietnam War has exploded in a southern village, killing four children and seriously injuring five other people.
Hieu Nghia village official Le Van Giang said three children aged four to 11 died at the scene yesterday afternoon and a six-year-old boy died at the hospital.
The blast seriously injured two other children and three men.
Mr Giang said the shell exploded when the children who found the shell from bamboo brush were playing with it. A villager had found the shell five years ago as they dredged a canal.
Vietnamese government figures show ordnance have killed more than 42,000 people since the war ended in 1975.
