U) Saudi Arabia background (S/NF) While the Kingdom of Saudi Arabia (KSA) takes seriously the threat of terrorism within Saudi Arabia, it has been an ongoing challenge to persuade Saudi officials to treat terrorist financing emanating from Saudi Arabia as a strategic priority. Due in part to intense focus by the USG over the last several years, Saudi Arabia has begun to make important progress on this front and has responded to terrorist financing concerns raised by the United States through proactively investigating and detaining financial facilitators of concern. Still, donors in Saudi Arabia constitute the most significant source of funding to Sunni terrorist groups worldwide. Continued senior-level USG engagement is needed to build on initial efforts and encourage the Saudi government to take more steps to stem the flow of funds from Saudi Arabia-based sources to terrorists and extremists worldwide. (S/NF) The USG engages regularly with the Saudi Government on terrorist financing. The establishment in 2008 of a Treasury attache office presence in Riyadh contributes to robust interaction and information sharing on the issue. Despite this presence, however, more needs to be done since Saudi Arabia remains a critical financial support base for al-Qa’ida, the Taliban, LeT, and other terrorist groups, including Hamas, which probably raise millions of dollars annually from Saudi sources, often during Hajj and Ramadan. In contrast to its increasingly aggressive efforts to disrupt al-Qa’ida’s access to funding from Saudi sources, Riyadh has taken only limited action to disrupt fundraising for the UN 1267-listed Taliban and LeT-groups that are also aligned with al-Qa’ida and focused on undermining stability in Afghanistan and Pakistan.
