A World War II bomb has been found and defused near the German capital's famous Alexanderplatz. Authorities say they were able to safely destroy the 100-kilogram behemoth's detonator.

An unexploded 100-kilogram (220-pound) bomb from World War II was unearthed at a construction site near Berlin's Alexanderplatz and later defused, police said on Twitter in the early hours of Saturday morning.
Police said there were "unexpected technical problems" but that they were "quickly taken care of."
Authorities had closed off an area within a 300-meter (1,000-foot) radius of the bomb as it was being defused but said only part of the area needed to be evacuated.
The evacuation zone covered parts of the Alexa shopping area, an above-ground rail line, several busy roads and some residential tower blocks, including a nursing home.
The US bomb was found at a depth of about three meters and had an intact detonator, police said. It was to be defused throughout Friday, with authorities warning the operation could cause traffic disruptions into the night.
Nearly 75 years after the end of the Second World War, Germany is still littered with bombs and other unexploded ordnance. Experts have said that some 3,000 devices still remain in the German capital's subsoil.
Alexanderplatz is one of Berlin's busiest areas, with numerous shops and residences located near the square that is home to the city's iconic TV tower.
Many decades after the World War II ended, unexploded bombs are still found across Germany.

What is unexploded ordnance?
Unexploded ordnance (UXO or sometimes also abbreviated to UO), unexploded bombs (UXBs), or explosive remnants of war (ERW) are explosive weapons such as bombs, shells, grenades, land mines, naval mines and cluster munitions that did not explode when they were deployed. Unexploded ordnance still poses the risk of detonation, even decades after they were used or discarded.

Why does Germany have a bomb problem?
Between 1940 and 1945, US and British forces dropped 2.7 million tons of bombs on Europe. Half of those bombs targeted Germany. Experts estimate that close to a quarter of a million bombs did not explode due to technical faults. Thousands of these bombs are still hidden underground, sometimes a few meters down and sometimes just below the surface.

How big is the issue?
The industrial Ruhr area and the Lower Rhine region were heavily bombed, as were the cities of Dresden, Hamburg and Hanover. So this is where most of the unexploded ordnance is found. Bombs are usually unearthed during construction work or are discovered during the examination of historical aerial images. Experts say it could still take decades to clear all of the remaining unexploded ordnance.

What happens when an unexploded bomb is found?
When confronted with the discovery of an UXO, UO or a UXB, bomb disposal experts have to decide whether to defuse it or to carry out a controlled explosion. Many have lost their lives on the job. German authorities are under pressure to remove unexploded ordnance from populated areas. Experts argue that the bombs are becoming more dangerous as time goes by due to material fatigue.

How many bomb disposal experts have died?
Eleven bomb technicians have been killed in Germany since 2000, including three who died in a single explosion while trying to defuse a 1,000-pound bomb on the site of a popular flea market in Göttingen in 2010.

Which was the biggest evacuation?
A 1.8-ton bomb dropped by Britain’s Royal Air Force (RAF) was found in the city center of Augsburg on December 20, 2016. The find prompted a large-scale bomb disposal operation and consequently the evacuation of over 54,000 people on December 25. To date, this remains the biggest evacuation for the removal of World War II unexploded ordnance in Germany.

Thousands affected by mass evacuations
A discovery of a unexploded bomb in a German city usually triggers a large-scale evacuation. The picture above shows the emergency response after 50,000 residents in the northwestern city of Hanover were forced to leave their homes in 2017. Many other evacuation efforts followed in the years since.
