Ukrainian President Volodymyr Zelenskyy said Sunday Russia used the powerful hypersonic Oreshnik ballistic missile during a mass drone and missile attack on Kyiv on Sunday which killed at least two people, marking the third time the weapon has been used in the four-year war.

The intense aerial assault damaged buildings across the Ukrainian capital, including near government offices, residential buildings and schools.

The Oreshnik, which is capable of carrying nuclear or conventional warheads, struck the city of Bila Tserkva in the Kyiv region, Zelenskyy said in a post on Telegram. The target was not immediately clear.

Russia first used the multiple-warhead Oreshnik on the Ukrainian city of Dnipro in November 2024. It was used a second time in January in the western Lviv region.

The combined attack included 600 strike drones and 90 air, sea and ground-launched missiles, according to Ukraine’s Air Force. Ukrainian air defenses destroyed and jammed 549 drones and 55 missiles. Around 19 missiles failed to reach targets, the Air Force said.

Earlier, Zelenskyy warned that Russia was planning to use the Oreshnik, citing intelligence from the U.S. and Western partners.

President Vladimir Putin said the Oreshnik, which means “hazelnut tree” in Russian, streaks at 10 times the speed of sound, or Mach 10, and is capable of destroying underground bunkers “three, four or more floors down.”
