Ukraine brought the war back to Moscow’s doorstep in a storm of drones, fire, airport chaos, and sirens, forcing Russians who once watched the invasion from a safe distance to hear the same terrible music they helped unleash.

Ukrainian drones struck targets across several Russian regions overnight, including an oil pipeline pumping station, a refinery and a fuel depot, Russian and Ukrainian authorities said on Sunday, in an escalating campaign of strikes against energy infrastructure often hundreds of miles inside Russia.

Ukrainian drones smashed into another Russian refinery overnight, starting a fire that produced huge clouds of black smoke, President Volodymyr Zelenskyy said Thursday, in what appeared to be the latest long-range attack on Moscow’s vital oil industry.

An explosive-laden Russian drone hit an apartment building in Romania early Friday, injuring two people, its government said, as Moscow’s forces attacked a nearby Ukrainian port.

A video showing a Pantsir-SMD-E being airlifted onto a skyscraper underscores Russian attempts to shield Moscow from increasing Ukrainian drone attacks.

NATO accused Moscow of reckless behaviour after Romania said a Russian drone had crashed into an apartment block in the alliance member state.

Romanian authorities said a Russian drone hit the roof of an apartment block and exploded, potentially raising tensions between Moscow and European nations.
