Russia's Ministry of Defense said Saturday powerful hypersonic "Kinzhal" missiles destroyed a military ammunitions warehouse in western Ukraine on Friday.
"On March 18, the Kinzhal aviation missile system with hypersonic aeroballistic missiles destroyed a large underground warehouse of missiles and aviation ammunition of Ukrainian troops in the village of Delyatin, Ivano-Frankivsk region," the ministry said.
CNN is unable to independently verify this claim.
The ministry has previously made claims that the highly maneuverable missile, which travels faster than the speed of sound, is unmatched for potency when coupled with its MiG-31 fighter jets.
In his 2018 annual address to Russia's parliament, President Vladimir Putin said Russia had developed an "invincible" missile that could deliver a warhead at hypersonic speed.
