Nagorno-Karabakh: What's at Stake in the Conflict Between Armenia & Azerbaijan?

As fighting continues between Armenia and Azerbaijan over the disputed territory of Nagorno-Karabakh, we look at the roots of the conflict that has already killed at least 700 people since fighting began in late September and which threatens to escalate despite two ceasefire attempts brokered by Russia. Nagorno-Karabakh, which lies inside Azerbaijan but is controlled by ethnic Armenians, was the site of a bloody conflict in the wake of the collapse of the Soviet Union.
