Amnesty International Thursday urged Azerbaijani and Armenian authorities to conduct immediate investigations into war crimes committed during the recent Nagorno-Karabakh conflict after videos emerged from private social networks showing extrajudicial killings, torture, and severe abuse.

In its press release, Amnesty said it analysed 22 videos that depicted, “extrajudicial executions, the mistreatment of prisoners of war and other captives, and desecration of the dead bodies of enemy soldiers.” The videos were originally shared on private messaging groups in the weeks after the signing of the Nagorno-Karabakh ceasefire agreement in early November. Both the footage and its content were verified as genuine, the former through Amnesty’s Crisis Evidence lab and the latter through an external forensic pathologist.

Denis Krivosheev, Amnesty International’s Research Director for Eastern Europe and Central Asia, called the crimes, “a clear violation of international humanitarian law,” and urged that, “Azerbaijani and Armenian authorities must immediately conduct independent, impartial investigations and identify all those responsible. The perpetrators – as well as any commanding officers who ordered, allowed or condoned these crimes – must be brought to justice.”
