VLADIMIR Putin has fired a terrifying wave of hypersonic missiles on Ukraine in a chilling revenge strike.
The attack targeted civilian areas in the capital Kyiv with deadly destruction also left across multiple districts.
In Ukraine six people have been killed and at least 28 wounded due to the Russian aggression.
The strikes – and deployment of lethal air-launched Kinzhal, or Dagger, hypersonic missiles – was seen as Vladimir Putin’s revenge for the assassination of the dictator’s top nuclear defence general in Moscow on Tuesday.
Iskander/KN-23 ballistic missiles were also deployed against Ukraine.
In the Holosiivskyi district of Kyiv, 630 residential buildings, 16 hospitals, 17 schools and 13 kindergartens were left without heat due to the Russian damage to a main heating pipeline, said mayor Vitaliy Klitschko.
