Military officers in the central province of Quang Ngai on Wednesday unearthed a 250-kilogram bomb left from the Vietnam War, the Vietnam News Agency reported.
The bomb, which is 1.65 meters long and 30 centimeters wide, was found beneath a rice field by farmers in a rural commune.
After being informed of the discovery, sappers arrived at the scene and removed the bomb to another location to defuse it.
According to local military officers, the bomb was made in 1967 and thrown by the American army into Ba To battlefield in Quang Ngai during the war.
In mid-November, workers of a construction company found 64 mortar shells around 1 meter deep underground in Quang Ngai's Son Ha District.
The mortar shells were then successfully defused.
