While the Norwegian jets are primarily in Poland to help defend a key logistics hub bringing materiel into Ukraine, rogue Russian missiles and drones have entered Polish airspace several times since the full-scale invasion began.

The Russian missiles sought out targets from the Lviv region in western Ukraine near Poland to Kharkiv in northeast Ukraine bordering Russia. The state energy company Ukrenergo reported emergency power outages in six regions. It often shuts down production during attacks as a precaution.

Russia launched a large-scale missile attack on Wednesday, some slamming into energy facilities that caused power losses in several regions of the country, officials said.
