Seoul shares fell on Thursday amid foreign selling and the expiry of options, with losses among refiners and automakers, including S-Oil Corp and Hyundai Motor, pressuring the market.

"Foreign investors, particularly those based in Europe, may [have been] settling positions as European debt uncertainties persist," said Y.S. Rhoo, a market analyst at Hyundai Securities. Foreign investors were sellers of a net 1 trillion Korean won ($928.9 million) worth of stocks, the biggest net sales in two months.
