UKRAINE – Ukraine launched a major night-time attack on a dozen Russian regions, Russian-held Crimea and the surrounding seas, in what appeared to be one of Kyiv’s biggest drone assaults since the Kremlin’s full-scale invasion more than four years ago. Russian air defenses intercepted 660 Ukrainian drones – the previous biggest Ukrainian attack over the past year, as Ukraine has accelerated its drone development, involving 556 drones on May 17.
