A British World War II bomb that caused the evacuation of residents in Koblenz, Germany was successfully defused Sunday, according to an Associated Press report.
The bomb, weighing 1.8 tons, along with a 275-pound U.S. bomb were found last month after a significant fall in the water level of the Rhine river, according to the Associated Press report.
Residents, cleared from homes, hospitals and prisons, were bussed to shelters outside of the city for safety.
Experts said the operation was risky because of the bomb's position.
"We have a British detonator which was surrounded by water for a long time and the explosives within the detonator react with water over time, which causes a high risk when the detonator is being removed," Bomb disposal expert Marco Ofenstein said, according to a Reuters report.
Koblenz was heavily bombed during World War II. City officials said 28 smaller war bombs had been found there since 1999, according to a Washington Post report.
