Russian drone strikes damaged five buildings in Kyiv, on Wednesday even as Ukrainian air defenses thwarted many more, authorities said. No casualties were reported, writes ABC NEWS.

The attacks underline how Ukraine’s biggest city remains vulnerable to the regular Russian attacks that have devastated infrastructure and other population centers, mostly in the country’s east and south in recent weeks.

Ukrainian President Volodymyr Zelensky, in a brief video statement, said the “terrorists” fired 13 Iranian-made drones, and all were intercepted. Such drones have been part of Russia’s firepower along with mortar, artillery and rocket strikes across Ukraine in recent weeks.

The head of the Kyiv city administration, Serhii Popko, wrote on Telegram that the strikes came in two waves, and shrapnel from the intercepted drones damaged one administrative building, while four residential buildings sustained minor damage.
