Two wartime bombs were exposed after construction vehicles had dug into a mountain cliff for the repair of a road in Vietnam.
The explosives were found in Minh Hoa District, Quang Binh Province, located in the north-central region.
They were about 2.6 meters in length and 340 kilograms in weight, with their bodies and detonators still intact.
The script 'M117 A1750LBS' was found on their covers.
They were discovered by construction workers who were fixing the section of National Highway 12A through Minh Hoa District of Quang Binh Province.
According to military engineers, the bombs were manufactured by U.S. forces and dropped in the locale by American aircraft in wartime to ravage 12A Route – a key passage for transportation – and prevent supplies for Vietnam’s soldiers in southern areas.
Military engineers in Quang Binh – in cooperation with the not-for-profit Mines Advisory Group – cordoned the area and detonated the two bombs on site due to their dangerous nature and precarious location, local military officers said on Tuesday.
