Lonewolf,
It was written in the Russian media (which I always read with some reservations) that a 2-seat MiG-21 of the Syrian AF (2-seat is a training aircraft, normal combat configuration implies a single pilot) was shot in the vicinity of the airbase. The rumors were that it was going for landing and thus was an easy target.
It was also said that one pilot ejected and landed safely in the village controlled by own forces. The second one intended to land the damaged aircraft but failed and met the ground. I am skeptical about the latter (intended to land), though...
