The woman, who has been identified as Malak Al Shehri, reportedly shared a photograph of herself without a hijab or abaya.

A woman in Saudi Arabia allegedly faces calls to be executed after posting a photo of herself seen without a hijab.

The photo was posted under the Twitter name Malak Al Shehri, and shows a woman without a hijab or abaya - a traditional body covering - in the streets of Riyadh.

Saudi Arabia, a conservative Muslim country, has a strict dress code for women. They must wear a hijab or abaya (full length covering) or face jail.

After the photo was posted, Al Shehri started receiving a torrent of abuse, with some demanding: 'Kill her and throw her body to the dogs' and 'We want blood', reported the International Business Times.

Al Shehri's tweet has since been delated, but that did not stop the abuse.

One message reportedly said: "The least punishment for her is beheading her", The Daily Mail reported.

Those vilifying Al Shehri have been using a hashtag that translates as "we demand the imprisonment of the rebel Angel Al Shehri".

A 21-year-old student, who wished to identified Sarah Ahmed, told the International Business Times this was an not uncommon occurrence for women in Saudi Arabia.

"I'm an atheist and I still wear the hijab in most places because that's how society here is. It's inexcusable to remove it, in fact, many of my atheist friends have to cover their faces because their families are more conservative than mine, and it's not just atheists, many Muslim women want to remove them," she said.

However, Al Shehri also has some supporters, with some calling her brave and couragous.

A person posting under the username @MajedAbboud wrote: "I'm amazed by the courage and the resilience of Saudi women".

"Its about time to protest against this discriminative abaya prison against women #shout_for_freedom," Farah Aqqad added.
