The Kingdom of Saudi Arabia has long employed a filtering regime that blocks content across a wide variety of categories. The government pervasively blocks regional media websites, websites with local oppositional content, and content related to human rights reports critical of the government. The government has expanded blocking around security and conflict. Since it launched military operations against the Houthi rebels in Yemen, the Saudi government has started blocking a large number of news websites affiliated with the Houthis and their ally, former President Ali Abdullah Saleh. It has blacklisted media websites affiliated with its regional rival Iran. It also blocks websites which are critical of Islam or advocate for secularism. In addition, the government pervasively blocks social content categories including porn, gambling, LGBT content, provocative attire, and alcohol and drugs. It also pervasively blocks Internet tools such as anonymizers and P2P platforms.
