The founder of an Iranian satellite TV station, GEM TV, has been shot dead in Istanbul.
Saeed Karimian was killed along with a business partner while driving in the city.
It is reported the pair was stopped by a jeep before shots were fired.
Karimian was sentenced last year in absentia to six years in prison by a court in Tehran over accusations of propaganda against the state.
City officials are quoted by local media as saying that initial police findings suggested a dispute over money may be behind the shooting.
