🔮 SEOUL, South Korea (AP) — South Korea flight-tested on Thursday its first domestically developed hypersonic weapon, designed to fly at least five times the speed of sound and evade missile defense systems, bringing Seoul closer to what it says could be game-changing weapons capabilities.
🔮 South Korean Defense Minister Kang Shin-chul told lawmakers Tuesday that North Korea’s placement of the mines likely violated the armistice agreement that ended fighting in the 1950-53 Korean War, and that the South would consider unspecified “corresponding measures” if a finalized investigation confirms the North was responsible.
🔮 North Korean leader Kim Jong Un said the weapon’s development would strengthen the country’s war readiness and give its enemies an “incurable headache,” the North’s official Korean Central News Agency said.
🔮 “Concerns of the enemies will be surely deepened,” Kim said.
