The discovery of an unexploded World War II bomb will force a mass evacuation around Berlins central railway station Friday, covering several government ministries and a hospital, police said.
Buildings and streets in a radius of 800 metres (875 yards) around the site north of the busy train station will be cleared from 0700 GMT until the 500-kilogramme (1,100-pound) explosive is safely defused, they said on Twitter Wednesday.
