The head of a British-based Saudi opposition group laughed off the U.S. government freezing his organization's assets, saying he had no assets and no links to Al-Qaeda. Another Saudi-run association named by U.S. officials as a possible conduit for terror financing denied it was channeling funds to Islamist extremists. The U.S. government Thursday froze the assets of the Movement for Islamic Reform in Arabia (MIRA) and said the group's head, Saad al-Faqih, was on the UN list of people associated with Al-Qaeda and the Taliban. The freeze came a day after U.S. officials expressed concern about three other Saudi-run associations that operate around the world - the International Islamic Relief Organization, the World Association of Muslim Youth, and the Muslim World League. Stuart Levey, U.S. Treasury under secretary for terrorism and financial intelligence, accused Faqih of using MIRA to provide Al-Qaeda with recruits and public relations help. Faqih, an exiled Saudi dissident, denied the allegations and said Washington was targeting him because of the threat he and his organization posed to the Saudi government, a U.S. ally. He said MIRA aimed to topple the Saudi monarchy by peaceful means.
