On the evening of October 20, the Armenian Defense Ministry declared that they had launched a large-scale counter-offensive against the advancing Azerbaijani forces in the Khudaferin Reservoir area, in the southern part of the Nagorno-Karabakh region. Armenian sources claimed that the attack had caused heavy losses for the ‘enemy’ and had pushed Azerbaijani troops into retreat. Pro-Armenian sources also said that the town of Zangilan had become a ‘trap’ for Azerbaijani troops and that a large group of the ‘enemy forces’ was now being eliminated there. On October 20, the Armenian Defense Ministry also released photos of a Turkish-made Bayraktar TB2 combat drone downed in the Nagorno-Karabakh combat zone. This is the second time, that the Armenian side appeared to be able to confirm that the Azerbaijani-Turkish bloc had lost a Bayraktar TB2. On October 19, Armenian sources showed a part of a Bayraktar TB2 optic system claiming that a drone had been downed. These drones are allegedly operated by the Azerbaijani military, but military sources say that drone operations are run with direct help from Turkish specialists, writes SouthFront.
