Extracted from Azeri War Crimes.Org:

On December 7, 2020, Azerbaijani-run channels on the Telegram messaging app uploaded video footage of the live execution of an 82-year-old Armenian civilian man. In the video, the victim is pinned down by a soldier wearing an Azerbaijani army uniform, with the distinctive cutaway helmets of Azerbaijani special forces. The soldier has an Azerbaijani flag can on the right shoulder and a red armband on his left. The victim is begging for his life repeatedly saying: “I beg you, for God’s sake” in the murderer’s own language. The other soldier hands the perpetrator a knife, which he uses to brutally cut the older man’s throat before the video abruptly ends.
The victim is identified by family and residents of his village as Yuri A., an 82-year-old from the village of Azokh. This horrific killing is believed to have taken place in the sector of Nagorno-Karabakh occupied by Azerbaijani troops since October 25. The exact date of the incident is not known. The video is independently verified by Amnesty International & The Guardian.

Author's note: Although some people are saying that the elderly man was "beheaded," in reality, in the full video—only a few extra seconds of footage—all that can be seen is the elderly man's throat being slit.
Also, one of the perpetrators was identified as Kamil Zeynalli, the soldier who hands the knife to the executioner. He is a blogger and bodybuilder. He was arrested in Russia but later released and welcomed as a hero in his country.
