Five people, including three children, died in central Vietnam when 30-year-old unexploded ordnance left behind from the Vietnam War exploded, police and state media reported Friday.
Three boys, aged 12 to 14, were killed in an explosion Thursday in the Hai Lang district of Quang Tri province, said a district police officer who identified himself only as Binh.
The boys discovered four unexploded bombs in bushes while looking after water buffaloes and the explosives went off when they examined them, he said.
Authorities suspect that farmers may have found the bombs while plowing their rice fields and put them in the bushes.
The area was a communist stronghold during the war and was heavily bombarded.

About 38,000 people have been killed by unexploded ordnance since the end of the Vietnam War in 1975, according to government figures.
