Since April, investigations have centred on DubaiIslamicBank, an institution with a history of problems, and on various mortgage lenders and developers.
The Center's letters strongly recommended that each firm examine their portfolios for exposure to DubaiIslamicBank and other named defendants in the Philadelphia lawsuit.
The Philadelphia lawsuit alleges that DubaiIslamicBank and other named Islamic Shariah banks have funneled zakat and "purified" funds to Islamic charities, which then funded al-Qaeda terror.
