The closest I can get is Nanchang A5 but none of the very few photos I can find are a really convincing match. The canopy bow is in the right place but nowhere near beefy enough nor the right shape - in fact it is so insubstantial I hardly see it being a part of a jet combat aircraft at all so I reckon this is a mockup and not the real thing.
The red handle and wanderlight next to it are in the right place.
I'd put money on it being a Mig 19 derivative though -
Not entirely confident with the call but by a process of elinination I'm saying the A-5IV/A-5M probably a mockup as exported to Pakistan with Rockwell-Collins avionics and instrumentation and a Mk10 seat.
Edit. Mig 21 derivatives are too big for this - it's not one of those.
