The barrage included 407 drones and 44 ballistic and cruise missiles, Ukrainian air force spokesperson Yurii Ihnat said.

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.

Russia mounted an intense and sustained barrage of Kyiv overnight, with missiles and drones targeting the Ukrainian capital where there was a succession of large explosions, Reuters reporters in the city said.
