According to the Arab News newspaper, the 19-year-old woman, who is from Saudi Arabia's Shia minority, was gang-raped 14 times in an attack in the eastern province a year-and-a-half ago.
Seven men from the majority Sunni community were found guilty of the rape and sentenced to prison terms ranging from just under a year to five years.
But the victim was also punished for violating Saudi Arabia's laws on segregation that forbid unrelated men and women from associating with each other. She was initially sentenced to 90 lashes for being in the car of a strange man.
On appeal, the Arab News reported that the punishment was not reduced but increased to 200 lashes and a six-month prison sentence.
