Senior Israeli military personnel have raised the issue of economic and security threats faced by the Jewish state as a result of Iran's collaboration with the Lebanese military group Hezbollah in the engineering of new drone technology.
Former Israeli Air Force officer Eli:
"I think they are doing good, and we have to be better. I think the cooperation between Iran and Hezbollah is showing everywhere in the world."
Recently a spy drone -- which Hezbollah claimed ownership of - was shot down over Israeli airspace, with the militia suggesting that the reconnaissance mission proved fruitful. Their leader Hassan Nasrallah later claimed that the drone had been built by Iran.
Drones are surveillance aircraft which can fly without a human pilot on board and can carry spying tools such as facial recognition software and thermal imaging cameras. Israel recently unveiled a new drone called "Heron 1" which can undertake sea and air missions to identify objects.
