You'd think that a woman playing a sport with a group of friends is an ordinary activity, but not in some Gulf countries, namely Saudi Arabia. 

A video allegedly capturing a woman playing volleyball with a group of men in the country has been making the rounds on Saudi Twitter and has caused quite the stir. 

The footage started circulating online over the weekend after it was uploaded on Twitter.

In it, a woman wearing a black abaya (floor-length garment) can be seen in the middle of a volleyball court, surrounded by two teams made up of male players.

While some news reports stated the woman is Saudi, adding that the footage was shot in the kingdom, these details remain unconfirmed. 

The video led to backlash...

Soon after it was posted online, the footage led to heavy backlash from Saudi tweeps who were upset over the incident. 

Some attacked the woman for breaking the strict mixed-gender rule that applies in public spaces across the kingdom. This rule states that men and women are to attend public events, including sports activities, separately. 

Others claimed the footage was not even shot in the kingdom, while many argued that it was. 

Tweeps were angered by the footage

"This is haram (unacceptable in Islam), she shouldn't appear in front of them without wearing a veil, let alone be playing volleyball with them."

And attacked it...

"This is so shameless." 

A few speculated the reasons behind the news being shared...

"What's your point behind this video? That it's OK to attend mixed-gender events? Or that she was with family? Or that it's normal for these things to happen?"

Saudis don't seem to be ready for mixed-gender public spaces...

"Ramadan should bring us together, but not like this."

Many tweeps thought the footage wasn't shot in the kingdom

"This playground isn't in the kingdom, I am sure of that." 

Others weren't so sure...

For many Saudis, "mixed" public spaces remain out of question...

While it remains unclear where the volleyball video was shot, the reaction to it comes as no surprise. Especially given the fact that, to many Saudis, mixed-gender public spaces and events are still deemed unacceptable. 

Even though such events are held in private in cities across the ultra-conservative kingdom, they rarely reach social media and when they do, most get cancelled or shut down. 

Earlier last year, a mixed-gender concert led to the shut down of a Saudi resort in Jazan after videos of it went viral online.
