Armenia and Azerbaijan accuse each other of moving troops to the border.
The chaotic and rapid collapse of the Soviet Union more than 30 years ago left complex and unresolved political conflicts.
One of them, between Azerbaijan and Armenia in the Nagorno-Karabakh region, has killed or injured tens of thousands of people in numerous conflicts and outbreaks of violence since then.
And after a brief but bloody war less than three years ago, tensions are escalating again.

And what role do Russia, the United States, the EU and Turkey play in this conflict?
