The Russian air force has once again bombarded Ukraine with missiles. On Monday morning, Ukrainian media reported explosions around the south-east Ukrainian city of Dnipro. According to observers, almost a dozen strategic bombers fired cruise missiles at targets in Ukraine. Hypersonic missiles of the Kinzhal (Dagger) type were also deployed. Air raid alerts were issued throughout Ukraine. The country has been fending off a Russian invasion for over 22 months. Moscow has already deployed thousands of missiles against targets in Ukraine.
