The presidential National Security Council held an emergency meeting Saturday after North Korea fired several cruise missiles toward the Yellow Sea, according to a presidential official.
The NSC meeting was led by Deputy National Security Adviser Lim Jong-deuk to discuss the readiness posture, the official said.
The Joint Chiefs of Staff announced the North's launch took place at around 4 a.m., days after South Korea and the United States wrapped up their major joint military drills.
South Korea and the US wrapped up the 11-day Ulchi Freedom Shield exercise on Thursday. The North has denounced the drills as a rehearsal for invasion.
The JCS did not elaborate further, pending an analysis. (Yonhap)
