North Korea said Thursday that its latest missile tests involved new hypersonic systems aimed at strengthening its nuclear war deterrent, as leader Kim Jong Un continues to build up weapons designed to overwhelm South Korea’s missile defenses.
The report by North Korea’s official Korean Central News Agency came a day after South Korea’s military said it detected the North firing multiple missiles from an area south of the capital, Pyongyang, and said they flew about 350 kilometers (217 miles) northeast before falling on land.
