Wounded U.S. veterans and family members of U.S. soldiers killed in Iraq sued five European banks on Monday, seeking to hold them responsible for shootings and roadside bombings because they allegedly processed Iranian money that paid for the attacks.

The lawsuit filed in U.S. District Court in Brooklyn, New York, named Barclays PLC, Credit Suisse Group AG , HSBC Holdings PLC, Standard Chartered and Royal Bank of Scotland Group PLC.

The banks did not immediately respond to requests for comment.
