Armenia's human rights defender, Arman Tatoyan, has officially labelled Azerbaijan's execution of two prisoners of war an "undeniable war crime".
"In these videos, members of the Azerbaijani army humiliate prisoners of war and then brutally kill them with extreme cynicism", he wrote on Facebook.
He said Armenia's representatives at the European Courts of Human Rights had already asked for copies of the videos. Mr Tatoyan said he would share the clips with the UN human rights commissioner, the Council of Europe and other international bodies.
