A group of Saudi activists have called on people to rally in favor of prisoners of conscience when the Arab kingdom marks its National Day on Sept 23.
The activists have proposed in their Twits that bottled waters, marked with calls for the release of political prisoners, be distributed among people.
In August, Saudis took to the streets in the Saudi capital city of Riyadh, calling for the release of their loved ones from prisons across the kingdom.
Saudi Arabia is known for its notorious prisons across the country, where over 30,000 political prisoners are held.
People are randomly arrested by the Saudi police just for looking suspicious, and are held behind bars for years before they are even charged.
According to Human Rights Watch (HRW), the Saudi regime ''routinely represses expression critical of the government.”
