Operational Command noted that all available systems were used to verify radar indications of a possible intrusion, but no violation was confirmed.
Officials suggested the signals may have been linked to weather conditions, pointing to a similar incident a day earlier in Romania.
On Saturday, the command explained that jets were scrambled in response to drone activity near Ukraine’s border, with Poland’s air defense placed on high alert before returning to normal several hours later.
The incident followed Prime Minister Donald Tusk’s claims on Wednesday that “dangerous” Russian drones were shot down over Poland—though no evidence was provided.
