Ukraine's security services have concluded that the prisoner of war killed by Russian soldiers in a clip that spread quickly across Ukraine and much of the world is Oleksandr Igorevich Matsievskyi, bringing an end to the dispute over his identity.

In the graphic 12-second clip that first circulated on Telegram last Monday, a detained combatant is seen standing in a shallow trench smoking a cigarette. The soldier, in uniform with a Ukrainian flag insignia on his arm, says Glory to Ukraine" and is then apparently shot with automatic weapons by a group of Russian soldiers.
