More than 60 women reportedly answered the call from Saudi activists to get behind the wheel as a display of defiance toward the society's ban on female driving, The Associated Press reported.

While the group has no way to verify the messages, they have received 13 videos and another 50 phone messages from women showing or claiming they had driven, said Saudi professor and campaigner Aziza Youssef.

Activists have not received any reports of arrests or women being ticketed by the police after what is likely the most successful effort to date from Saudi women defending their right to drive.

A security official said authorities did not arrest or fine any female drivers on Saturday, the day set for the campaign. He spoke to the AP on condition of anonymity because he was not authorized to speak to the media.

Youssef and four other prominent women activists received warnings from a top official not to drive, she told the AP.

She also said that "two suspicious cars" have been following her everywhere all day. "I don't know from which party they are from. They are not in a government car," she said.

Women are not specifically banned by law from driving, but they are not issued licenses and mostly rely on drivers or male relatives for transportation. Powerful clerics warn that female drivers will cause "licentiousness," while a prominent cleric said last month that driving a car harms a woman's ovaries.

May Al Sawyan, a 32-year-old economic researcher, told the AP that she drove from her home in Riyadh to the grocery store and back. Like other female drivers in Saudi Arabia, the mother of two had obtained her license from abroad.

"I am very happy and proud that there was no reaction against me," she said. "There were some cars that drove by. They were surprised, but it was just a glance. It is fine ... They are not used to seeing women driving here."
