Authorities detained a Saudi woman on Saturday after she launched a campaign against the driving ban for women in the ultraconservative kingdom

◼ Saudi woman detained for defying driving ban

Manal al-Sherif and a group of other women started a Facebook page called "Teach me how to drive so I can protect myself," which urges authorities to lift the driving ban. She went on a test drive in the eastern city of Khobar and later posted a video of the experience.

"This is a volunteer campaign to help the girls of this country" learn to drive, al-Sherif says in the video. "At least for times of emergency, God forbid. What if whoever is driving them gets a heart attack?"

Human rights activist Walid Abou el-Kheir said al-Sherif was detained by the country's religious police, who are charged with ensuring the kingdom's rigid interpretation of Islamic teachings are observed.
