South Korean war planes and navy ships have fired a barrage of missiles into the waters during one- day drills aimed at boosting a readiness against possible North Korean aggression.
Thursday's drills off the east coast were previously scheduled but they occurred two days after North Korea test- launched its first intercontinental ballistic missile.
South Korea's navy says the drills involve 15 warships including a 3,200-ton-class destroyer, helicopters and fighter jets.
After the launch, North Korean leader Kim Jong Un said he will never put his weapons programs up for negotiations.
