North Korea reports an intermediate-range strategic missile drill supervised by Kim Jong Un.

Reuters reported that North Korean state media KCNA described Saturday's launch as a drill for troops operating a hypersonic strategic weapon system. KCNA said the missile was fired from eastern North Korea and struck a target in the sea off the country's east coast.

South Korea's military confirmed detecting a ballistic-missile launch but gave a lower flight-distance estimate of more than 700 kilometres. Reuters noted that North Korea has conducted more than 10 missile tests this year.
