俄国防部发言人声称俄军使用超音速导弹摧毁了乌西一个地下仓库。如果证实,这将是战争史上首次使用超音速导弹。
乌克兰和西方还没证实。
A spokesperson for Russia's defence ministry has said that Moscow has destroyed an underground depot in western Ukraine using hypersonic missiles.
Igor Konashenkov claimed that the warehouse had been housing missiles and "aviation ammunition of Ukrainian troops".
Russia has never before admitted to using hypersonic missiles in combat.
They are cutting edge ballistic missiles that can fly in the upper atmosphere at more than five times the speed of sound.
According to the Russian military, the "Kinzhal" missile system used in the strike is capable of hitting targets at a range of more than 2,000km (1,242 miles) and can overcome all existing air and missile defence systems.
