Armenian Ambassador-at-Large Edmon Marukyan tweeted about Azerbaijan's constant claims that the Nagorno-Karabakh issue is an internal matter. 

"Azerbaijan keeps claiming that the issue of Nagorno Karabakh is an internal matter. Just let me remind that no internal matter was dealt with by 3 PMs of UNSC for decades, OSCE and now the EU. The issue of Human Rights wasn't considered an internal issue for 7 decades, since WW2," the statement reads.
