Riyadh: Saudi authorities on Thursday pulled a novel by an award-winning author from bookstores after readers denounced some passages as pornographic, sparking controversy in the ultra-conservative kingdom.

“Thursday’s Visitors” is an Arabic fiction novel by well-known columnist and writer Badriyah Al Bishr, who often focuses on the daily struggles of women in Saudi Arabia.

“The ministry of culture and information has withdrawn the book ‘Thursday’s Visitors’... and opened an investigation into the matter,” said a spokesman for the ministry.

The book chronicles one young woman’s journey of self-discovery through Thursday get-togethers where women share their joys and sorrows.

But some of the content was deemed as sexually graphic.

“How can a book with this content be sold in the children’s books section?” one Saudi reader wrote on Twitter to Jarir, a prominent bookstore chain.

“I did not check the content of the book before buying it, but your mistake is worse.”

In its response to the tweet, Jarir tweeted: “We agree with you. The copies have been withdrawn. We thank you for your observation.”

There was no immediate response from Al Bishr.

“Why are you all being so dramatic? Just skip the page and move on,” said a Saudi Twitter user in response to a conservative backlash against the author.
