Mehrnoushe Solouki, a 38-year-old graduate student from Montreal, Canada, was arrested in February in Iran while working on a documentary film on the Iraq-Iran war.

Solouki was freed in March after posting bail and had since been under house arrest in Teheran pending the outcome of an investigation. Iranian authorities do not recognize dual citizenship and insisted Solouki was an Iranian national.

Solouki boarded an Iran Air flight from Teheran that was due to land in Paris on Friday morning, according to a diplomatic source in Teheran.

‘We are pleased that Madame Solouki is returning to France,’  said foreign ministry spokesowman Pascale Andreani.

The journalism student was arrested after interviewing relatives of members of Iran’s armed opposition, the People’s Mujahedeen.

Iranian authorities confiscated her notes and film footage and called her in for questioning.
