A 300-kilo bomb which was found at a construction site in the northern province of Son La has been safely detonated.
According to authorities in Yen Chau District, the bomb was discovered at the construction site of the Ta Vai Bridge upgrade project on National Road 6 in Chieng Hac Commune on April 5.
The bomb, which was identified as being left from the French War, has been safely denotated by local army forces.
Vietnam is one of the most heavily bomb-and-mine-contaminated countries in the world.
Statistics from the National Steering Committee on Overcoming Post-War Unexploded Ordnance and Toxic Chemical Consequences showed that during the French and American wars between 1945 and 1975, more than 15 million tonnes of explosives were dropped on Vietnam, which was four times higher than the amount used in World War II.
At present, bombs and mines are still covering up to 6.1 million hectares or 18.7 percent of the country’s land area.
