Tkachenko accused Russia of hitting residential areas with the drone attack, saying a high-rise building the the Solomyansky district of Kyiv was damaged. Kyiv’s Mayor Vitali Klitschko also reported fires in the districts of Holosiivskyi and Darnytskyi of the Ukrainian capital.

With its devastating drone assault on Russia’s strategic bomber fleet, Ukraine’s SBU security service pulled off the kind of spectacular operation that has long fed the mystique of top spy agencies like Israel’s Mossad.

Ukraine said its “Operation Spiderweb” attacked Russian warplanes worth hundreds of millions of dollars, utilizing drones that each cost under $1,000 and were launched from wooden containers carried on trucks.
