World War II bomb defused in Berlin

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.

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.
