In other story... North Korea launched another missile this morning into the East Sea.
This was the regime's 11th launch this year, and it's believed it was fired from a submarine.
Kim Ji-yeon has more.
South Korea's Joint Chiefs of Staff has confirmed that North Korea fired a ballistic missile from waters near the eastern port
city of Wonsan in North Korea's Kangwon-do Province.
The missile was fired in an easterly direction at 7:11AM Wednesday.
The maximum flight altitude was some 910 kilometers... and the flight distance was around 450 kilometers.
The Joint Chiefs identified the launch as a "Pukguksong-type" missile.
During an emergency meeting, the National Security Council voiced grave concerns saying the North may be developing a submarine-based ballistic missile... at a time Pyeongyang and Washington are preparing for working-level talks.
Submarine-based ballistic missiles are believed to be more threatening than missiles fired from land since the launch site is harder to detect in advance.
It's believed the North is developing a Pukguksong-three missile and submarines of more than 3-thousand tons... and that the recent launch could have been planned in advance... regardless of progress on denuclearization talks.
The North had fired Pukguksong-one missiles three times from submarines in 2016... and fired a Pukguksong-two missile from land in 2017.
"Meanwhile, Tokyo has corrected its analysis on the missile launch... saying that it was in fact one missile that had been fired and not the initial two that it had announced. Tokyo says it's investigating further on whether the one missile had separated into two.
Kim Ji-yeon, Arirang News."
Defense Minister Jeong Kyeong-doo, meanwhile, has said that South Korea, under the military intel-sharing pact with Japan, had asked Japan for the specifics of the missiles launched by North Korea this morning.
His remarks came when asked about whether Korea and Japan shared information regarding today's missile launch... during the parliament's annual audit of government ministries.
