More than three years into Russia's full-scale invasion, Ukrainians across the country retreat each night to bomb shelters and metro stations in a nightly ritual.

Authorities say a Russian missile hit a Ukrainian army training ground in an attack that killed three soldiers and wounded 18 others.

The Russian military attacked Ukraine with 83 aerial weapons, namely 76 drones, an Iskander-M ballistic missile, five S-300/S-400 anti-aircraft guided missiles and a Kh-22 cruise missile on the night of 2-3 August.
