(CNN) Several people have been arrested in Iran over the downing of a Ukrainian passenger plane as Iranian President Hassan Rouhani warned that those responsible would be punished.

Gholamhossein Esmaili, the spokesman for Iran's judiciary, was quoted by the semi-official FARS news agency Tuesday as saying that an investigation into the crash had started and several arrests had been made. He did not provide details on how many people had been arrested or what their roles in the incident may have been.

Among the arrests is the person who filmed "the scene of the missile hitting the Ukraine airplane" for further investigation, according to Iran's semi-official Tasnim News Agency.

There was no mention of the person's name or what charges, if any, they are facing.

Speaking in Tehran on Tuesday, Rouhani called for the punishment of those behind the downing of Ukraine International Airlines flight 752.
