Canadian-Iranian academic Homa Hoodfar flew back into Montreal on Thursday, after authorities in Iran released her from custody.
She had been detained since June, accused of acting against national security.
“I didn’t feel that I would be released until I was in the jet and the jet was in the air because in Iran nothing is complete until it is complete,” the anthropologist told reporters.
A campaign was launched to secure freedom for the 65-year-old expert on gender and Islam who was in Iran to visit relatives and for study purposes.
Barred from leaving the country in March, she was freed from custody for humanitarian reasons including illness, Iran said.
Iran’s Revolutionary Guards have arrested at least seven dual-nationality citizens or expatriates visiting the country over the past year, the highest such number in acknowledged detention in recent years.
