The dollar was little changed against the major world currencies Wednesday, as traders took a wait-and-see approach to the U.S.-led coalition's military action against Afghanistan. The greenback recently traded at 91.37 cents per euro, down slightly from 91.32 Tuesday. The dollar changed hands at 120.20 yen, compared with 120.11 in the prior session. The U.S. currency has lost 2% against the euro and 1.5% against the yen since the Sept. 11 terrorist attacks on New York and Washington. The British pound fell to a five-week low against the dollar as investors appeared concerned about the U.K.'s involvement in the military strikes. The pound traded at $1.4503 earlier, the lowest level since Sept. 7.
