JERUSALEM (AP) — Saudi Arabia confirmed in a letter to the United Nations that a female fitness instruction who was popular online received an 11-year prison sentence but did not specify any of her alleged “terrorism offenses.”

Though the kingdom insisted the case had nothing to do with the instructor’s online presence, human rights activists say the conviction levied against Manahel al-Otaibi shows the limits of expression in Saudi Arabia.

It also highlights another side of the kingdom, now run day-to-day by Saudi Crown Prince Mohammed bin Salman, who under his 88-year-old father King Salman has dramatically liberalized some aspects of women’s lives in the country.

“Her charges related solely to her choice of clothing and expression of her views online, including calling on social media for an end to Saudi Arabia’s male guardianship system, publishing videos of herself wearing ‘indecent clothes’ and ‘going to the shops without wearing an abaya,’” said Amnesty International and ALQST, a London-based group advocating for human rights in Saudi Arabia that’s followed al-Otaibi’s case.
