A new headache arises in an area well-accustomed to turbulence.

Armenia condemned its rival for both the most recent developments and the “mass crimes” it claims Azerbaijan committed during hostilities three years ago. The foreign ministry’s statement noted that the escalation in the region in 2020 also took place in September.

Azerbaijan has pursued “ethnic cleansing” of Armenians living in Nagorno-Karabakh, the ministry statement alleged, claiming Baku feels “impunity” given its open acknowledgement of its actions.

Earlier in the day, Azerbaijan’ Defense Ministry announced it had launched an operation against what it claimed to be Armenian military assets deployed in Nagorno-Karabakh. Yerevan denies the presence of the units in the contested region. Baku has pledged to only attack military targets and claimed that it was seeking to “thwart large-scale provocations” by the Armenian side.

Here’s hoping Iran, Turkey, or Russia drop the hammer before things spiral again.
