South Korean President Lee Myung-bak was presiding over a security-related meeting on Saturday to check follow-up measures after North Korea fired a barrage of shots on a South Korean island earlier this week, officials said, Yonhap reported.
The meeting also comes one day before the U.S. and South Korea are set to begin military exercises in the Yellow Sea in a show of force that North Korea warned will take the peninsula to the "brink of war."
Lee was discussing measures to counter another possible North Korean attack and studying ways to levy sanctions on the communist state, according to the officials.
