NATO accused Moscow on Friday of reckless behaviour and pledged to “defend every inch of Allied territory” after Romania said a Russian drone had crashed into an apartment block in the alliance member state during an attack on neighbouring Ukraine.Romania’s defence ministry said a woman and a child suffered minor injuries in Galati near the border with Ukraine overnight after radar tracked a Russian drone entering Romanian airspace.Photos from the scene showed charred and damaged brickwork on the roof of the 10-storey apartment block which Romanian authorities said was hit by a drone that exploded on impact, tearing through a top-floor flat.Russia’s TASS news agency cited Kremlin spokesman Dmitry Peskov as saying President Vladimir Putin had been informed about the incident. Russian Foreign Ministry spokeswoman Maria Zakharova said all the accusations about Russian drones flying in Europe were unsubstantiated, RIA reported.Separately, Dmitry Medvedev, deputy chair of Russia’s powerful Security Council, warned European leaders that drones would continue to stray into their countries and prevent their populations from sleeping peacefully.It was the first time a densely populated area in a NATO country had been hit causing injuries during Russia’s war in Ukraine, and the incident is likely to increase tensions on the alliance’s eastern flank as member states worry about the war spilling over their borders.Not sure if drone was Russian: PutinRussian President Vladimir Putin on Friday said it was too early to say if the drone which crashed into an apartment block in Romania was Russian, and suggested it could have been a Ukrainian drone. “Who in Romania says that this is a Russian drone?” Putin asked reporters at a news conference in Astana, Kazakhstan.
