Speaking at an international conference at the Baku ADA University (Azerbaijan Diplomatic Academy) on April 29, Azerbaijani President Ilham Aliyev said that Russia supplied weapons to Armenia through Kazakhstan and Turkmenistan during the hostilities in Nagorno-Karabakh in 2020. This was reported by the Turkish news agency Anadolu .
According to Aliyev, Armenia intended to draw Russia into the war through the CSTO. This was not possible, but Russia regularly supplied Armenia with weapons from Mozdok and Rostov.
Azerbaijan turned to Georgia with a request to block air and ground routes for the delivery of weapons to Russia. Georgia satisfied Baku's request.
Azerbaijan also asked Kazakhstan, Iran and Turkmenistan to close its airspace for the supply of weapons from Russia to Armenia. However, according to Aliyev, military deliveries through these countries continued.
In September 2020, Azerbaijan did not allow the Russian Air Force A-50 airborne early warning aircraft No. 76702, which was returning from Syria to Russia, to fly over its territory.
Because of this, the plane had to fly over Turkmenistan, which, it seems, allowed the flight.
It should be noted that Turkmenistan has the status of neutrality, which implies non-interference in the military actions of other states.
