Krakow, Poland / Weesp, Netherlands Construction sites in two separate countries experienced accidental discoveries of undetonated WWII UXO on the same day. The Netherlands and Poland both saw evacuations and emergency responses to deal with the uncovered ordnance.

The first was a site for a new university residence building at Jagiellonian University in Krakow where workers uncovered more than 200 unexploded WWII anti-tank mines, prompting response from Army EOD teams. According to a police statement, authorities cordoned off the surrounding area while army sappers safely removed the explosives for neutralization.

Wiesbaden, Germany A 1,000-pound American WW II-era aerial bomb discovered near a U.S. Army installation in western Germany prompted evacuations and restricted base access.

The munition was unearthed during road construction in the Erbenheim district, the primary access route to Clay Kaserne. German EOD technicians immediately secured the site under guard and scheduled a disposal operation the next day.

Authorities established a 750-yard evacuation cordon, displacing dozens of nearby residents and forcing the closure of several major transportation routes. Affected infrastructure included sections of the A66 autobahn, the B455 federal highway, and the Wiesbaden-Cologne railway.

The disposal operation significantly disrupted activities at U.S. Army Garrison Wiesbaden. Military police enforced safety measures, closing the installation's main gate to all traffic, pausing base shuttle services, and restricting base access strictly to inbound personnel via an alternate entry point.

Krakow, Poland More than 200 WWII UXO were discovered by construction crews at an excavation site in Krakow. As soon as the workers realized that the items resembled artillery shells, work was paused and emergency services were notified.

Plymouth, England Police officers and Royal Navy UXO technicians responded after an unexploded WWII bomb was discovered on a building site in Plymouth, forcing the evacuation of approximately 1,200 homes in the area.

The explosive experts worked through the night assessing the 550-lb device, and a 400-meter cordon was established in the area, according to the Plymouth City Council.

The munition was identified as a German SC250 air-dropped weapon. Four hundred tons of sand was provided by the Council to stabilize and secure the device while enhanced Xray equipment was used for a detailed assessment.

Colombes, France An unexploded WWII munition found during construction on Rue des Champarons forced the evacuation of several thousand residents in Colombes, a suburb of Paris. According to police, approximately 800 officers responded to secure the area while explosives experts attempted to defuse the device.

After unsuccessful attempts to remove the detonator, a controlled detonation plan led to all within a 450-meter radius evacuation zone. Local official Alexandre Brugere said that the intervention was "risky," due to the bomb's age and condition.

Guam Local and federal responders successfully coordinated the retrieval of two separate UXO discoveries within a two-day span.

The first incident occurred when the Guam Police Department (GPD) received reports of a suspected mortar round located along Route 17 near Windmill Farm in Yona. The Guam Homeland Security and Office of Civil Defense (GHS-OCD) coordinated with Joint Region Marianas to dispatch a military EOD team. EOD Technicians safely secured the area and cleared the munition, requiring no road closures or evacuations.

The following evening, a second mortar shell was discovered at Rizal Beach in Hågat. GPD officers responded to secure the shoreline perimeter while GHS-OCD once again requested military EOD support. The scene was declared safe less than an hour later, again without the need for evacuations or road closures.

Singapore A 250 kg WWII bomb that was discovered at an airport terminal construction site was rendered safe with no impact on airport operations, according to the Changi Airport Group (CAG).

Following its discovery, the ordnance was examined by the Singapore Armed Forces' EOD team and determined to be unsafe to move, requiring a controlled on-site disposal. The Ministry of Defence (MINDEF) reported that personnel from the Chemical, Biological, Radiological and Explosives Defence Group constructed protective works to mitigate any fragmentation resulting from the disposal operation.

MINDEF said that EOD worked with personnel from the police, the Defence Science and Technology Agency (DSTA), CAAS, and CAG to protect the public and minimize any airport disruptions.
