Debris of what appears to be a Russian drone crashed into a field in Poland on Wednesday, Polish authorities said.

"Once again, we are dealing with a provocation by the Russian Federation, with a Russian drone," Polish Defense Minister Wladyslaw Kosiniak-Kamysz said.

"We are dealing in a crucial moment, when discussions about peace (in Ukraine) are underway."

Local police found burned metal and plastic in a corn field outside the village of Osiny, in the east of the country. No casualties were reported.

What do we know about the drone?

Polish media published photos of what appeared to be remains of the drone, including a charred engine and a propeller. The explosion left a crater 6 meters (20 feet) wide.

The Polish Foreign Ministry said initial findings indicated the drone was a Russian-made version of the Shahed drone — an Iranian design that is commonly used to attack Ukraine.

Polish general Dariusz Malinowski said the aircraft "was a decoy drone, which was not armed but carried a self-destruct warhead."

Poland condemns 'violation of airspace'

Polish Foreign Minister Radoslaw Sikorski condemned "a new violation of our airspace from the east."

"The Foreign Ministry will protest to the perpetrator of this violation," he wrote on social media.

There have been a number of incursions into Polish airspace since Russia launched its full-scale invasion of Ukraine in 2022, raising alarm in the EU and NATO member state.
