The war raging between Armenia and Azerbaijan over the disputed Nagorno-Karabakh region has dragged in a complex web of foreign countries.
The neighboring former-Soviet states are fighting over the Nagorno-Karabakh region, which is controlled by the self-proclaimed Republic of Artsakh, an ethnically Armenian enclave that is internationally recognized to be a part of Azerbaijan but has never been under Azeri rule.
The current flare-up is the most serious escalation since the early 1990s and has raised tensions between key regional actors, most notably Russia, Turkey, Iran, and Israel.

Russia: Regional powerhouse trying to mediate
Russia is the most influential country in the South Caucasus region but has remained on the sidelines in the current flare-up and called for an end to hostilities.
Russia has a military base in Armenia and sells arms to both Armenia and Azerbaijan in a balancing act that gives it considerable influence and leverage over both countries.
Over the years, Moscow has used its position to play the role of a mediator.
According to Laurence Broers, Associate Fellow of the Russia and Eurasia program at Chatham House, Russia has a security-driven approach based on the idea of “pivotal deterrence,” a term he coined.
“[Russia] is a pivot moving between Armenia and Azerbaijan with a range of different kinds of policies, being a security guarantor to Armenia, providing weapons to both sides and mediation initiatives,” Broers told Al Arabiya English. According to Broers, the recent escalation is a dilemma for Moscow. On the one hand, Russia is a co-chair of the main mediation entity for this conflict.
