A US lawyer says thousands of Iraqi families may join a class action against Australian wheat exporter AWB because of the kickbacks it paid which helped fund Saddam Hussein's regime.

The class action against AWB, its US office and a French bank has been filed by lawyers acting for two women whose husbands were killed by Hussein's regime.

Lawyer John Murray says the case alleges AWB entered into a conspiracy to fund a Government which carried out genocide.
