The only woman from Iran to win an Olympic medal announced over the weekend that she has permanently left the country, accusing the government of injustice by exploiting Iranian women as political tools.

Kimia Alizadeh posted a statement Saturday on Instagram explaining the anger and sadness behind her decision to defect from Iran, apparently planning to settle in a European country.

Should I start with hello, a goodbye or condolences? the 21-year-old taekwondo fighter wrote in Farsi. I am one of the millions of oppressed women in Iran who they have been playing with for years.
