From the BBC:
Television journalists were travelling with Russian forces who captured a group of rebel fighters sheltering in the village of Alkhan-Kala.
Mr Yandiyev, dressed in camouflage, can be seen in the footage standing injured near a bus.
He is questioned by a Russian general who eventually shouts: “Take him away, finish him off, shoot him, damn it!”
Mr Yandiyev was then led away and has not been seen since.
General Alexander Baranov, who was seen on camera sending him off to be shot, has since been promoted and awarded a Hero of Russia medal.
