A Russian drone reportedly crash-landed in eastern Poland overnight.
An unidentified object landed in a cornfield near the village of Osiny, at around 2am.
Local police said they found burned metal and plastic at the scene.
A spokesperson for Poland’s foreign ministry said the object was a Russian version of a Shahed drone – which is made in Iran.
The country’s news agency PAP reports an explosion damaged nearby houses, but adds nobody was injured.
Poland’s Armed Forces Operational Command said its airspace wasn’t violated from neighbouring Ukraine or Belarus.
Poland’s foreign minister Radoslaw Sikorski said: “Another violation of our airspace from the East confirms that Poland’s most important mission towards NATO is the defence of our own territory.
“There will be a protest from the Ministry of Foreign Affairs against the perpetrator.”
The country’s defence minister told reporters: “Once again, we are dealing with a provocation by the Russian Federation, with a Russian drone.
“We are dealing in a crucial moment, when discussions about peace are under way.”
