"We think it came from Azerbaijan. Azerbaijan works closely with Israel. So its Israeli UAV."
Sorry but thats no proof at all.
Azerbaijan has UAV of similar class. They are called Aerostar:

They even license producing them. So its very little chance that Azerbaijan will by another UAV of similar class.
UAVs of Azerbaijan are Aerostar, Orbiter-2M , Heron, Hermes 450. The shown UAV by Iran is obviously non of them.
On the contrary, Armenia has a UAV which is exactly similar to this UAV and is most probably developed by Iran from Iranian Shahed-123 for Armenia. It has a blue background with orange spots(blue and orange from Armenian flag) as well, which 100% matches with this shown UAV. Also, the range of the shown UAV is so small that it cannot even reach from northwestern border to Natanz and such places in central Iran. So, there are two options left. 1. Iranians have mistakenly shoot down their own UAV. 2. They have deliberately shoot it down to make propaganda against Azerbaijan and Israel.
