A land mine left over from the 1970s exploded in northern Vietnam, killing three children and wounding six others, two seriously, state media reported Sunday. The three children, all aged 10, were killed at the scene as they tried to extract scrap metal from the land mine on Friday in Lai Chau province, the Tuoi Tre (Youth) newspaper said. Six other children, also the same age, were wounded and two remained in critical condition, the newspaper said.
