On Friday, March 28, 2014, a federal judge in Chicago ruled that survivors of a 1997 terrorist attack blamed partly on Iran can't seize museum pieces in U.S. collections to help pay a $412 million judgment against Iran. The ruling stems from a long-running legal battle that museum officials elsewhere watching closely. They feared their own collections could be put at risk if the judge had allowed collections of Persian antiquities at Chicago's Field Museum and the University of Chicago to be seized. (AP Photo/M.
