GoPro footage released by Ukrainian forces captures the attempted detainment of Russian POWs. Everything is smooth until one of the detainees attempts to pull a grenade on the Ukrainian troops.

It's unclear when and where the footage above was recorded. That said however, the professionalism of the Ukrainian troops in this video is worth mentioning. Shortly after the grenade detonates, the Ukrainian with the pistol can be heard telling his partner "don't shoot these ones" in reference to the Russian Soldiers still remaining compliant. He then moves to the Russian POW who attempted to kill them with the grenade and ensures that the Russian is entirely incapable of mounting a second attack.
