The materials were put into two holes on a cajuput hill in Trieu Son Commune, Trieu Phong District.
The pieces of unexploded ordnance have been discovered in Quang Tri
The first hole contained nearly 400 explosive items, while the remainder was detected at the second hole just 15 metres further away.
