Poland has demanded an explanation from Moscow after saying a Russian cruise missile aimed at Ukraine entered its territory.

“On March 24 at 4:23 a.m., there was a violation of Polish airspace by one of the cruise missiles launched tonight by the long-range aviation of the Russian Federation,” the Operational Command of the Polish armed forces said on X.

“The object flew into Polish [air]space near the village of Oserdow (Lublin Voivodeship) and spent 39 seconds in it,” Operational Command said. “It was observed by military radar systems throughout its flight.”

The report came after Ukrainian officials said Russia had launched about 20 missiles and seven Shahed attack drones targeting the western Ukrainian region of Lviv, which is near the Polish border. There were also multiple explosions reported in the Ukrainian capital of Kyiv.
