Emergency crews have been dispatched to the crash site but cannot assist because the area is currently ablaze, Koulivand said on IRINN, a state-run media outlet. Koulivand said the crash site is between the cities of Parand and Shahriar.
Flight-tracking service FlightRadar 24 said in a tweet that the jet had been in service for about three and half years.
