Poland closed four airports including its main Chopin Airport in Warsaw on Wednesday, according to the U.S. Federal Aviation Administration.

Poland places its forces on full alert and closes several airports as ‘hostile objects’ violate airspace.

Poland's military command said Polish airspace was repeatedly violated by "drone-type objects" during the Russian attack across the border in Ukraine.

Russian drones sent into Polish airspace were reportedly heading to a NATO base used to supply Ukraine, it has been revealed.
