A cluster bomb exploded and killed a man in Nghe An province Tuesday morning as he stepped on it while working his field.

Luong Pho Mun, 72, died on the spot upon the explosion.

Border guards said they have cleared the area later.

His neighbors in Nam Can Commune, of Ky Son District, said in a news website Dan Tri report that a lot of unexploded ordnance from wartime are still hidden in the commune’s ground.

They have claimed many lives in similar circumstances, locals said.
