The U.S. Government has declared the Al Aqsa Martyrs Brigade, under the leadership of Yasser Arafat, an official terrorist organization. This means that financial sanctions will be imposed on the organization and that it will be banned from engaging in transactions in the United States. Unlike Fatah and Force 17 - Arafat groups whose banning many Congressmen have also asked for - the Al Aqsa Brigade is not believed to have assets abroad.
