(ANSA-AFP) - WARSAW, SEP 10 - Poland said Wednesday it had scrambled aircraft alongside allies to shoot down "hostile objects" violating its airspace during a Russian attack on neighbouring Ukraine, a first for a NATO country during the war. "Aircraft have used weapons against hostile objects," Defence Minister Wladyslaw Kosiniak-Kamysz said on social media, adding: "We are in constant contact with NATO command." The incursion came as Russia unleashed a barrage of strikes across Ukraine, including in the western city of Lviv, around 50 miles (80 kilometres) from the Polish border. Russian drones and missiles have entered the airspace of NATO members -- including Poland -- several times during Russia's three-and-a-half-year war, but a NATO country has never attempted to shoot them down. A cornerstone of the Western military alliance is the principle that an attack on any member is deemed an attack on all. The operational command of Poland's military slammed the "unprecedented" airspace violations, saying it had spotted around a dozen drone-type objects and downed some of them. "This is an act of aggression that has created a real threat to the safety of our citizens," it said. Prime Minister Donald Tusk confirmed that weapons had been used against the invading objects, saying on social media that an "operation related to multiple violations of Polish airspace is underway".
