North Korea fired eight short-range ballistic missiles towards the sea off its east coast on Sunday, likely its largest single test, a day after South Korea and the United States ended joint military drills, Reuters reported.
The bilateral exercises involved an American aircraft carrier for the first time in more than four years.
South Korea's Joint Chiefs of Staff said that at least eight missiles were fired from the Sunan area of the North Korean capital Pyongyang and they flow between 110 km-600 km (70-370 miles) at altitudes between 25 km to 90 km.
In response, South Korea President Yoon Suk-yeol convened a National Security Council meeting and ordered "expanded deterrence of South Korea and the United States and continued reinforcement of united defence posture".
The NSC meeting conclued that the missile launch was North Korea's "test and challenge" of the security readiness of South Korea's new administration, which took office last month, the president's office said in a news release.
