The planned disposal of a 500-kilogram bomb dropped by the U.S. Air Force during World War II will result in the evacuation of 16,500 residents in the inner city of Frankfurt on Sunday.
The bomb was discovered a week ago during building works near the headquarters of the European Central Bank in the German financial center.
The disposal of the bomb has been scheduled for between noon and 6 pm local time on Sunday, with the evacuation zone stretching into the inner city and across the River Main.
Residents of a care home and elderly people's homes in the area will be moved to hospitals the day before the planned operation, taking important personal documents and any essential medication with them.
Rail services in the city could also be temporarily halted, and trams, buses and the metro will come to a standstill from Sunday morning.
As compensation, evacuees will receive free tickets to visit the city's museums and its well-known Palm Garden.
Frankfurt's fire services are well-versed in bomb disposal operations. In September 2017, 65,000 residents had to be evacuated so that a British "blockbuster" bomb weighing 1.8 tons could be removed.
