In late August 2026, emergency sirens were accidentally activated in Zamość and several surrounding counties in the Lubelskie Voivodeship. Authorities stated the three-minute signal was triggered by mistake during a scheduled “silent test” of the warning system. Local officials apologized, noting that while there was no actual threat, the error caused public concern regarding the reliability of the regional warning system.

By early September, routine siren testing was scheduled for several districts in Warsaw, including Śródmieście and Mokotót, to verify system efficiency. Officials emphasized these were standard checks and did not indicate danger.
