Vietnam's endless war
Although the Vietnam War ended 22 years ago, its deadly legacy continues to maim and kill innocent Vietnamese.
A tragic example of this occurred last April.
Seven Thai and Kho Muu minority children were killed in the village of Chieu Luu, in Nghe An province near the Laos border, as they rushed from their classroom after lessons.
What happened? Some villagers say heavy rains earlier in the day had washed away the topsoil in the village, leaving a weapon as exposed and as deadly as on the day it was laid by the United States army.
The bomb had been left behind from a war which began - and ended - a generation before the young victims were even born.
Another version of the story is that a boy had found the small bomb in a field, put it in his pocket, and it later exploded when another child pushed him.
