Ukrainian strikes reportedly targeted Engels and Dyagilevo airfields — two key hubs for Russia's long-range bomber fleet, as well as logistics sites in Russia's Kursk Oblast.

Russia says the 'massive attack' on Kyiv was in retaliation to Ukrainian strikes. It comes after the Kremlin launched a wave of drone strikes on Ukraine’s capital late on Thursday night, forcing residents to flee underground to shelter. Volodymyr Zelenskyy reported that the assault was comprised of more than 400 drones and 40 missiles.

Russia launched a drone and missile attack on Ukraine's capital and other parts of the country on Friday, officials say.
