Women in Saudi Arabia have been openly driving cars in defiance of an official ban on female drivers in the ultra-conservative kingdom.
The direct action has been organised on social network sites, where women have been posting images and videos of themselves behind the wheel.
The Women2Drive Facebook page said the direct action would continue until a royal decree reversed the ban.
Last month, a woman was arrested after uploading a video of herself driving.
Manal al-Sherif was accused of "besmirching the kingdom's reputation abroad and stirring up public opinion", but was released after 10 days having promised not to drive again.
Campaigners have not called for a mass protest - which would be illegal - but have asked women who have foreign driving licences to drive themselves as they go about their daily life.
"All that we need is to run our errands without depending on drivers," said one woman in the first film posted in the early hours of Friday morning.
If you're on Twitter, you can track the protest with the #women2drive hashtag. Reports of police stopping the drivers are starting to filter in.
