A U.S. nonprofit is warning businesses to avoid getting entangled with the Qatari government, alleging that the tiny Gulf state, currently embroiled in a regional diplomatic dispute, harbors terrorists and is a funder of extremist groups. “Qatar has a long history of providing support for extremism and terrorism, including but not limited to vast financial and material support to internationally designated terrorist groups and willing accommodation of internationally designated or wanted terrorist leaders and financiers,” Counter Extremism Project CEO Mark Wallace wrote in his letter. Over seven footnoted pages, Wallace details Qatar’s alleged misconduct, including sections on “terror financing overseas,” “money laundering,” “harboring of terrorist individuals” and “risk to employees resident in Qatar.” Wallace accuses Qatar of offering financial support, either directly or indirectly, to Hamas, Al Qaeda in the Arabian Peninsula and the Taliban.
