Sirens mistakenly sound in Zamość and Biłgoraj during silent emergency test

Accidental siren activation in eastern Poland

On Sunday, 23 August 2026, emergency sirens sounded shortly before 7:00 AM across parts of Lublin Voivodeship in eastern Poland, startling residents in the city of Zamość, the town of Biłgoraj, and surrounding municipalities. The sirens emitted a continuous, steady acoustic tone that lasted for approximately three minutes before falling silent. In the Polish civil defence system, a three-minute uninterrupted signal denotes an alarm cancellation rather than an active warning of imminent airborne danger. Because no emergency notification had been issued in advance to local mobile phones, the sudden early-morning noise caused widespread confusion among citizens. Zamość City Hall and Zamość Mayor Rafał Zwolak promptly released statements on social media platforms, confirming that the siren activation was unintended and assuring the public that no genuine security threat had occurred.

Operational mistake during silent system testing

The acoustic signal was initiated by the Lublin Voivodeship Crisis Management Center (WCZK) during a scheduled technical exercise. Provincial authorities had planned to perform a diagnostic silent test to evaluate system capacity and verify that remote siren units were functioning correctly. During execution, operators erroneously triggered an audible transmission across multiple local siren networks instead of maintaining the silent diagnostic mode. Marcin Bubicz, the spokesperson for the Lublin Voivode, addressed the technical mishap, emphasizing that the system broadcast an alarm cancellation signal and that regional authorities regretted the early-morning disruption.

It was a three-minute, continuous sound, which is an alarm cancellation. There is no reason for concern. We apologize to all concerned residents for the situation.

Alert protocols and distinct regional drills

Spokesperson Marcin Bubicz clarified the administrative protocol regarding public notifications, explaining why residents in Zamość and Biłgoraj did not receive advance text messages from the Government Centre for Security (RCB). Under established civil protection guidelines, silent diagnostic tests do not require advance warnings to the public because sirens are intended to operate without generating any acoustic sound. These routine diagnostic procedures are conducted specifically to measure the technical throughput and responsiveness of regional alert infrastructure without disturbing daily life. In contrast, an entirely separate acoustic exercise had been scheduled for Sunday between 7:00 AM and 11:00 AM across Parczew County, also situated within Lublin Voivodeship. Because that planned exercise involved audible sirens, the RCB had distributed warning text messages on Saturday to everyone located within Parczew County.

Scrutiny following earlier missile warning failures

The accidental activation in Zamość and Biłgoraj follows scrutiny of Lublin Voivodeship's emergency alert architecture after a previous military incident involving a Russian Kh-101 cruise missile that crashed near Tarnawa-Kolonia. During that incident, the Government Centre for Security ordered sirens to sound across 17 regional counties, but Lublin Voivode Krzysztof Komorski later confirmed that sirens failed to activate in 10 of those 17 jurisdictions. An assessment revealed that physical radio transmission units were locked inside municipal government offices, while designated on-duty personnel lived more than 10 kilometers away. Biłgoraj County Starost Andrzej Szarlip also highlighted communication delays, pointing out that an explosion occurred at 3:45 AM, whereas the email instruction directing the on-duty firefighter at the dispatch center to activate sirens did not arrive until 3:49 AM.
