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

Russia launched large-scale drone and missile strikes on Ukraine's capital and other parts of the country early on Friday, local officials said. At least four people were killed in Kyiv and at least 20 have been injured, the city's mayor Vitaliy Klitschko 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.
