Russia battered much of Ukraine with scores of missiles and drones that officials say killed four people, injured more than a dozen, and damaged energy facilities

Russia said it downed 158 drones in what appeared to be one of the largest Ukrainian drone attacks yet. Fires broke out at energy facilities, including in Moscow.

Ukraine launched one of its biggest-ever drone attacks on Russia over the weekend, hitting a refinery and power station deep inside the country, according to videos posted on social media and geolocated by CNN.
