 Ukrainians destroyed Russian air drones in air. Ukrainian authorities say they thwarted a Russian attack on Kiev and the surrounding region as their air defense system intercepted and destroyed 13 explosive laden drones, although wreckage from some of them damaged five buildings. The attempted strikes underlined how vulnerable Ukraine's capital remains to the regular Russian attacks that have devastated infrastructure and population centers in recent weeks, mostly in the countries east and south. But they also highlighted Ukraine's claims of increasing efficiency in intercepting weapons, something that Patriot missiles from the US may soon help boost. Ukrainian President Vladimir Zelensky in a brief video statement said the terrorists fired 13 Iranian-made drones and all were intercepted. Such drones have been part of the firepower along with rockets, missiles, shelling motars, and artillery, as Russia targets power stations, water facilities, and other public utility sites. The snow-covered capital remained largely calm after the attack, which occurred around daybreak. As the working day began, authorities sounded the all-clear. The head of the Kiev city administration, Sergei Popko, wrote on telegram that the attempted strikes came in two waves. Wreckage from the intercepted drones damaged an administrative building and four residential buildings, he said.
