WWII Bomb Detonation in Colombes Triggers Mass Evacuation
Thousands of residents were evacuated from Colombes, a northern suburb of Paris, on Sunday as authorities safely detonated a World War Two bomb discovered last month. The evacuation affected those living within a 450-meter radius of the bomb's location.
Residents were instructed by police to vacate their homes by 07:00 local time (05:00 GMT) to allow bomb disposal experts to carry out the operation. An initial attempt to remove the bomb's detonator was unsuccessful, according to French media, which led officials to decide on a controlled explosion at the site.
The Prefect of Hauts-de-Seine confirmed in a statement that the operation was "carried out successfully" and that the evacuation order was lifted by early Sunday evening.
Discovery and Preparations
The bomb was found on 10 April during construction work on Rue des Champarons. Following its discovery, the site was secured and the device was covered with sand while authorities prepared for its removal.
Local official Alexandre Brugère described the operation as "risky" and emphasized that it required a "high level of preparation".
Evacuation and Security Measures
Approximately 800 police officers were deployed to enforce a 900-meter-wide evacuation zone around the bomb site. A secondary, larger zone extending one kilometer from the location was established where residents were allowed to remain indoors but were restricted from outdoor activities.
Emergency alerts were sent to residents instructing them to leave the area, with clear communication that re-entry would not be permitted until the operation's completion.
"The authorities told us to close our windows and shutters when we left the house, but we didn't take anything - we left everything as it was,"
said one resident, Alida, to the newspaper Le Parisien.
Reception centers were organized to accommodate evacuees, including provisions for vulnerable individuals requiring medical assistance.
Controlled Detonation and Aftermath
Bomb disposal experts conducted the controlled detonation at 15:20 on Sunday. The evacuation order was lifted shortly after 16:00, allowing residents to return to their homes.
Context of WWII Bomb Discoveries in Europe
Undetonated bombs from World War Two continue to be discovered across Europe, even 86 years after the war began. Such munitions are often uncovered during construction projects, particularly in urban areas where population density increases the risk associated with these devices.
In recent years, numerous bombs have been found in London, prompting evacuations of tourist areas and temporary closures of facilities such as London City Airport.
In Paris, a 500-kilogram bomb was located and defused last year near Gare du Nord during railway bridge construction.
