Freedom

The women tweeting for their freedom in Saudi Arabia

"I'm a dead soul in a living body and I hope that doesn't happen to my little sister," Sara, a Saudi woman, tells CNN.

Sara is one of a growing number of Saudi women who are challenging the country's male guardianship system using social media.

In Saudi Arabia, every woman has a male guardian -- often a father or husband, sometimes a brother or son -- who has the power to make a range of critical decisions on their behalf.
