A house in Poland that was damaged during a Russian drone incursion was hit not by drone debris, but by an air-to-air missile fired from an F-16 fighter jet, according to the Polish newspaper Rzeczpospolita, which cited “state agencies responsible for national security.”

The house, in the village of Wyryki-Wola in the Lublin region of eastern Poland, belonged to a retired couple. The owner said that in the early hours of September 10, as drones crossed into Polish airspace from Ukraine and Belarus, one of them struck the upper part of the house, tearing through the roof and damaging the bedroom. He and his wife were not injured.

“It was an AIM-120 AMRAAM air-to-air missile from one of our F-16s,” a source told the newspaper. “Its guidance system failed mid-flight, and it didn’t detonate.” According to the source, the warhead never exploded, and the three-meter missile, weighing more than 150 kilograms (about 330 pounds), crashed into the house.

The Lublin regional prosecutor’s office has declined to provide details, describing the object that struck the house only as an “unidentified flying object.” “At this time, the object has not been identified as a drone or as drone fragments,” the office said in a statement.

Around 20 drones entered Polish airspace that night. Prosecutors said they recovered debris from 17 of them, most of which were “false targets” — dummy drones without payloads, meant to overwhelm air defenses. Based on numerous photos and videos posted by local residents, several Russian-made Geran drones fell on Polish territory.

Poland and NATO have said the drones that violated Polish airspace were Russian and that the incursion was a deliberate provocation. Polish and allied fighter jets were scrambled to intercept them. Russia has flatly denied involvement, with the Defense Ministry claiming that “no targets in Poland were planned for strikes.”
