The fresh flare-up between Azerbaijan and Armenia, which began with mortar and artillery exchanges early Sept. 27 and became full-fledged drone warfare within hours, continued into its fourth day Wednesday. How the conflict will evolve is a crucial question in an energy-rich region where Russia, Turkey and Iran are major stakeholders with competing interests.
The scene of the clashes — the mountainous Nagorno-Karabakh region — has been occupied by Armenia since a war in the 1990s despite being officially recognized as part of Azerbaijan. The clashes have concentrated in Murov Mountain dominating the north of the region and the Fuzuli area near the Iranian border to the south.
