Armenian Prime Minister Nikol Pashinyan on Tuesday warned of a “very high probability” of an escalation on the restive border with Azerbaijan and in the Nagorno-Karabakh region, over which the arch foes fought two wars.

“There is a very high probability of an escalation along Armenia’s border (with Azerbaijan) and in Nagorno-Karabakh,” Pashinyan said in a press conference, accusing Baku of stepping up “aggressive rhetoric” amid the “humanitarian catastrophe” caused by Baku’s blockade of the contested territory.
