Around 13,000 people are to be evacuated Sunday from their homes in the German city of Dortmund after local authorities identified suspected World War II bombs in the city center.
The city, in Germany’s industrial Ruhr region, is to be brought to a standstill by a mass evacuation affecting retirement homes, hospitals, and the main train station.
In an online statement, Dortmund city hall said authorities had identified four locations where they suspected unexploded bombs dropped by Allied forces during World War II are buried.
The suspicions were based on “anomalies” detected during construction projects, the statement said.
“Only an excavation” could confirm the existence of bombs, it added.
Residents within a 500-meter radius of each location were told to leave their homes by 8:00 am (0700 GMT) on Sunday, with excavation work to begin later in the day.
Preparations were already in full swing on Saturday, with 58 patients evacuated by ambulance from two hospitals.
Residents at two retirement homes were also moved to safety a day ahead of the work.
The city hall tweeted images of containers being set in place to form a protective wall around the affected area.
The total area to be evacuated covers a large part of Dortmund’s city center, including the main train station and nearby National Football Museum.
The train station will be closed Sunday morning, with trains rerouted to avoid the city.
The unearthing of World War II-era bombs is a common occurrence in Germany, but local media claimed this case could be the largest such evacuation ever seen in the Ruhr region.
In 2017, around 65,000 people were temporarily evacuated — the largest such operation since 1945 — when a huge British bomb weighing 1.4 tons was discovered in Frankfurt.
Last September, 15,000 people were evacuated from their homes while a 250-kilogram device was defused in Hanover.
