The quiet of a Kyiv cemetery is broken by a trumpet salute, then a burst of rifle fire.

Soldiers stretch a Ukrainian flag over a shiny wooden coffin and stand silently alongside in the sparkling white snow. A woman cries, her face crumpling.

Natalia is burying her husband for the second time.

Vitaly was killed three years ago fighting in the eastern Donbas and his first grave was in their home town of Slovyansk. But Russian forces have advanced since then and the area is increasingly under attack.

So Natalia had her husband's grave exhumed and Vitaly's remains moved hundreds of miles to Ukraine's capital.
