To the best of my knowledge it came from a series of documentaries called "Dog Fight - Desert Aces" or something similar from the History Channel.
(All rippingly good stuff!)
If you spend a few minutes searching you can find several fights involving Mirage III vs various Middle Eastern opponents. There is a particularly good one about a Mirage III against a Jordanian Hunter. This ends in a slow speed scissors which it looks like the Hunter should have won. According to the Israeli pilot the Hunter pilot bottled out a fraction early and ended up being splashed after an epic low level chase over the desert floor.
