Najla Hariri was shortly arrested on Wednesday while she was driving to her daughter’s office.

Hariri is among a group of activists who launched an Internet campaign in June 2011 urging Saudi women to defy the driving ban in the country.

“I have not signed any commitment that forbids me from driving,” AFP quoted Hariri as saying after her release.

Hariri said she had repeatedly told the police that there was no law forbidding women from driving in Saudi Arabia.

Saudi Arabia is the only country where women are not allowed to drive.

Police has recently arrested several women in Jeddah for defying the driving ban.
