Nearly 13,000 residents were evacuated in Frankfurt yesterday as experts defused an unexploded World War II bomb, local emergency services said.  The 500-kilogramme British bomb had been found on a construction site in Germany's financial capital on Thursday, the emergency services said. A 700-metre evacuation radius was set up in the west of the city centre in an area that included a number of old people's homes, heating and internet infrastructure and facilities of the Deutsche Bahn national rail operator. Some 75 years after the war, Germany remains littered with unexploded ordnance, often uncovered during construction work. In 2017, the discovery of a 1.4-tonne bomb in Frankfurt prompted the evacuation of 65,000 people -- the largest such operation since the end of the war in Europe in 1945.
