Vietnamese officials say experts have successfully defused the biggest U.S. bomb found since the Vietnam War ended nearly 30 years ago.

Explosives were successfully removed from the 5.5-ton bomb and then safely detonated.

The bomb was found last month in the forests of Gia Lai province in the Central Highlands by villagers who were searching for fire wood.

Officials say they believe the bomb was dropped by the U.S. Air Force during the war.

Land mines and unexploded ordnance left over from the Vietnam War regularly maim or kill people, mostly children and farmers. Last week, the U.S. government awarded a $5 million grant to the Vietnam Veteran's Memorial Fund to assist with mine clearance and education.
