"The videos, detailed below and verified by The New York Times, show a horrific moment of the war, but do not show how and why Russian soldiers were killed," the article says.
According to the publication, a total of two such videos were published.
On one of them, a Ukrainian soldier filmed the battles for Makeyevka on his phone.
The other video was most likely taken from a drone used by the Ukrainian Armed Forces to monitor the offensive.
It shows the bodies of 12 Russian soldiers, next to which traces of blood can be seen.
What happened between the two videos is unknown.
The NYT writes that the last Russian soldier to leave the house probably tried to resist and started shooting.
Moscow and Kyiv accuse each other of killing prisoners.
The Russian side accuses Ukrainian forces of "merciless execution of unarmed Russian prisoners of war", and Ukraine's human rights commissioner Zmytser Lubinets says that Russian soldiers opened fire during the act of surrender.
Dr. Rohini Haar, a medical adviser of the "Doctors for Human Rights" organization, told the publication that most of the prisoners of war, judging by the published footage, were shot in the head.
"There are pools of blood.
This indicates that they were simply left there for dead.
It seems that there was no effort to pick them up or help them," he said.
The expert also added that the killing or wounding of a soldier who, "laying down his weapon or having no more means of protection, surrendered of his own accord, is a violation of the laws of international armed conflict."
Nevertheless, Iva Vukusic, an expert on investigating war crimes at Utrecht University, noted that it is difficult to establish the fact of a war crime based only on video evidence.
She emphasized that the decisive factor in this case is the time when the Russian soldiers were shot.
In addition, the actions of the Russian military could be considered a simulation of surrender as a trick against the Armed Forces.
It is also considered a war crime under the Geneva Conventions.
The UN also did not ignore what happened and confirmed that it is necessary to conduct an investigation.
"We are aware of these videos, and we are studying them," the spokeswoman for the UN Human Rights Office, Marta Hurtado, told Reuters.
After the videos were circulated on social networks, the Russian authorities demanded that international organizations condemn the "outrageous crime" and conduct a thorough investigation.
The head of the HRC under the President of the Russian Federation, Valery Fadeev, handed the note to the Office of the UN High Commissioner for Human Rights, the OSCE, the Council of Europe and human rights organizations.
The Investigative Committee of the Russian Federation opened a criminal case under two articles: "murder of two or more persons, committed by a group of persons in connection with the performance of their official activities" (paragraphs "a", "b" and "g" of part 2 of Article 105 of the Criminal Code of the Russian Federation) and " cruel treatment of prisoners of war, use of prohibited means and methods in an armed conflict" (Part 1 of Article 356 of the Criminal Code of the Russian Federation).
On November 20, the Deputy Prime Minister in charge of European integration of Ukraine, Volga Stefanishyna, announced that Ukraine will investigate a video that allegedly shows the shooting of Russian soldiers.
She added that the short, edited video clips were "highly unlikely" to reflect Russia's claims of a war crime, as the USU had "absolutely no interest in executing anyone" and had orders to capture as many Russians as possible for exchange.
