Iran may use the veil as a tool of oppression, but the hijab is also the weakest pillar of an embattled regime trying to forestall its own "Berlin Wall" moment, an Iranian-American activist based in New York tells AFP.
Masih Alinejad, 45, who fled Iran in 2009, became known in 2014 after she launched a social media campaign called mystealthyfreedom.org that encourages Iranian women to protest against the obligation to wear the hijab in their country.
