::::::Yes, but what is the path forward?  There are four choices:  (1) keep article with Massacre in title;  (2) keep article, but change title to "Incident" or "Alleged Massacre"; (3) delete the article via WP:AFD process;   (4) delete the article by merging it into Nagorno-Karabakh War.   We dont have enough information to select one of those choices.  If no editor can provide sources denying the massacre, then maybe (1) is best.  But if sources that deny are found, then (2) may be best.  If the topic is very rarely mentioned, then (3) or (4) may be best, but an AfD should be initiated if an editor want to do (3) or (4).
