North Korea has fired around a dozen missiles off its eastern and western coasts, with at least one of them landing near the tense sea border with South Korea, after making veiled nuclear threats.
In response South Korea said its fighter jets fired three precision-guided missiles near the eastern border with the North.
It comes just hours after North Korea threatened to use nuclear weapons to get the US and South Korea to "pay the most horrible price in history" as it has intensified its fiery rhetoric targeting the ongoing large-scale military drills between its rivals.
