During construction and excavation work near the intersection of Grzybowska and Żelazna streets in central Warsaw, six unexploded objects believed to be World War II artillery shells were discovered.

In response to the find, emergency services—including police, firefighters, and sapper units—established a safety zone with a radius of 300 to 400 meters. The operation necessitated the evacuation of approximately 4,000 residents from eight nearby buildings. The situation also caused significant disruptions to local traffic and public transportation, specifically affecting bus lines 106 and 157.
