Escalating Azerbaijan-Armenia Conflict 🚨

President Putin of Russia has called for an end to hostilities in the Nagorno-Karabakh region -- he said the fighting between Azerbaijan and Armenia was a tragedy --- while Iran warned it could escalate into a wider regional war. The current fighting is the worst seen since a war between Azeris and Armenians in the 1990s.

Under international law -- the territory of Nagorno-Karabakh belongs to Azerbaijan -- but it's populated and governed by ethnic Armenians.
