Reports in Azerbaijani media claim that several tons of weapons were dispatched from Russia to Armenia between July 17 and August 4.
The flights, using an IL76 military cargo plane, reportedly took a roundabout route from the southern Russian city of Rostov-on-Don to Armenia, avoiding the direct route – over Georgia.
Russian arms for Armenia are not unusual: The two countries are allies via the Collective Security Treaty Organization (CSTO) and Russia has long provided Armenia with weapons. But Azerbaijanis protested to the scale and timing of these consignments.
According to the Russian publication, Avia.Pro, Azerbaijan is more concerned because of the arms shipment included the latest weapons like air defense, electronic warfare systems, short, medium, and long-range radars, electronic suppression systems, artillery weapons, and S-300 air defense system.
