In a significant operation, over 20,000 residents of Cologne were evacuated following the discovery of three unexploded World War II bombs in the city. This evacuation, described as the largest in Cologne since 1945, involved careful planning and execution by local authorities. The removal operation concluded successfully with the defusal of the bombs, leading to the lifting of the evacuation order and allowing residents to return to their homes. The incident highlights the ongoing challenges posed by wartime relics in urban areas.
