Yesterday a video was published on twitter where you could see some MiG-21s recently delivered to the LNA aviation near Tobruk.
The video shows 9 single-seater aircraft (F.01, F.02, F.03, F.04, F.07, F.09, F.10, F.11, F.12) and, in the background, a two-seater. The aircraft would be a gift from the Egyptian Air Force.
Really, however, the video is not taken yesterday but probability was taken in May 2017.
We cannot say with certainty how many and which of these aircraft are actually operating today.
