Ukrainian drones over Moscow force airport closures, strike S-400 unit

Ukrainian drones struck Moscow overnight, forcing the suspension of operations at three airports — Domodedovo, Vnukovo and Zhukovsky. Sochi and the town of Sirius in Krasnodar Krai were also targeted; Sirius is believed to host an air-defence battalion equipped with S-300 and S-400 systems. Ukraine continues to extend the reach of its drone strikes deep into Russian territory.
