Are the compensation funds – taken as compensation for the people after the Gulf War – permissible, and are the interest accrued on them later also permissible?

The compensations paid after the Gulf War are permissible as long as they are not based on a forbidden contract, such as usury, and as long as one does not take more than his rightful due. As for the interest paid for the period during which funds were lost during the invasion of Kuwait, it is considered usury and is not permissible, unless it is equivalent to the expenses and costs incurred to obtain these rights.
