World War II bomb in Siegburg: 1,700 residents evacuated!
On June 28, 2025, an explosive incident occurred in Siegburg when a 250 kilogram aircraft bomb from the Second World War was found on a construction site at the intersection of Hopfengartenstrasse and Alfred-Keller-Strasse. This discovery led to an immediate evacuation of residents within a radius of 400 meters; a total of around 1,700 people had to quickly leave their homes. The fire department informed the population via loudspeaker announcements, and city administration employees were also on the move to reach residents directly at their door. A collection point was set up in the cafeteria of the Neuenhof school center, where 322 people found a safe place.
The bomb, which is classified as live, poses a real danger. The evacuation measures were officially initiated on June 27, 2025 at 10:15 p.m. and are valid until July 4, 2025, 10:15 p.m. During this time, it is recommended to avoid the affected area as far as possible and to obtain current information from local media, e.g. B. on local radio. Emergency numbers such as 110 and 112 should only be dialed in real emergencies. In addition, the citizen information and warning app (BIWAPP) points out the importance of the information issued by the respective authorities and reminds of the urgency of informing neighbors and acquaintances.
Defusing by explosive ordnance disposal service
The defusing of the aerial bomb was initiated on the night of June 28, 2025 following an inspection by the public order office. It is expected to take around 30 to 60 minutes. The responsible explosive ordnance disposal service is responsible for the safe disposal of such explosive ordnance that dates back to the Second World War and has been repeatedly found in Germany over the years. These departments specialize in defusing and disposing of unexploded ordnance and are therefore experienced in working under potentially dangerous conditions.
The situation is serious for the population in and around Siegburg. Coordination between the fire department, police and other relevant authorities is of utmost importance to ensure the safety of everyone involved. The explosive ordnance disposal service, which is responsible for civil explosive ordnance disposal in Germany, regularly carries out such operations and is based on years of experience and specialist knowledge. In recent years there have been increasing reports of the discovery of bombs that were not recovered in Germany due to the final years of the war, and this is anything but an isolated case.
Rules of conduct for residents
Those affected are urgently asked to avoid the area around the site and to only act if directly requested by the emergency services. Anyone who needs help leaving their apartment should contact the city administration immediately. It is crucial that the evacuation runs smoothly so that no one is put in danger. Recommendations for action had already been made in advance to ensure that people behaved correctly in a potentially dangerous situation. One thing is certain: safety is the top priority!
The development of these incidents once again shows how important it is to trust local warning systems and apps such as BIWAPP. These services are designed to inform the population quickly and efficiently so that no time is lost in an emergency.
