Qatar has been accused of allowing terror financiers to operate within its borders, which has been one of the justifications for the Qatar diplomatic crisis that started in 2017 and ended in 2021. In 2014, David S. Cohen, then United States Under Secretary of the Treasury for Terrorism and Financial Intelligence, accused Qatari authorities of allowing financiers who were on international blacklists to live freely in the country: "There are U.S.- and UN-designated terrorist financiers in Qatar that have not been acted against under Qatari law."[1] Accusations come from a wide variety of sources including intelligence reports, government officials, and journalists.
