North Korean leader Kim Jong Un oversaw the test-firing of two cruise missiles launched from a submarine, state media said Monday, the latest in a series of tension-raising moves by the nuclear-armed state. “The cruise missiles flew in the sky above the East Sea… to hit the island target” on Sunday, state-run news agency KCNA reported. South Korea’s military had said Sunday that it had detected cruise missiles fired near waters around the North’s Sinpo area.
