Tens of thousands of German residents in Frankfurt are being told to evacuate by Sunday morning for authorities to defuse a World War II-era bomb.

A Frankfurt police spokesperson said as many as 70,000 people could be affected, according to The Local Germany, which would make it Germany’s largest evacuation since World War II.

“Due to the large size of the bomb, extensive evacuation measures must be taken,” Frankfurt police said. They tweeted a map of the circular evacuation zone, an area which stretches slightly over 3 kilometers, or about 1.8 miles, at its longest on the map.
