South Korean stocks opened sharply lower Wednesday as continued military attacks between the United States and Iran drove oil prices higher. The Korea Composite Stock Price Index fell 184.73 points, or 2.7%, to 6,651.07 as of 9:15 a.m. Major U.S. stocks also closed lower overnight after a new round of U.S. strikes on Iran increased oil prices and heightened concerns about inflation in the world's largest economy.
