South Korea's military says the North launched two projectiles that appear to be short-range ballistic missiles toward the East Sea.
The Joint Chiefs of Staff said it detected the suspected missiles at 8:00AM and 8:05AM.
"Our military detected two projectiles this morning that appear to be short-range ballistic missiles flying toward the East Sea going northeast from the Hamhung area."
This is the sixth launch this month, coming just two days after the North fired two cruise missiles on Tuesday.
It said the missiles traveled 190 kilometers at an altitude of 20 kilometers, and said the U.S. and South Korean intelligence agencies are assessing the matter to verify further details.
It also said that it's closely monitoring the situation to be ready for any additional launches.
Because they traveled a relatively short distance and at a lower altitude, experts say the missiles may have involved the super-large caliber multiple rocket launcher called KN-25 or an apparent variant of Russia's Iskander, KN-23.
Another expert says it could have been a new type of missile that North Korea is developing, but what's more important is that it flew at a very low altitude.
"A missile flying about 200 kilometers, at a maximum altitude of 20 kilometers means that it's hard for our missile interceptor to intercept. And it will not easily be detected on our radar because it takes time, which gives us little time to respond."
Earlier in January, on the 5th and the 11th, North Korea tested missiles, that it claimed were "hypersonic missiles".
Then on the 14th, the regime launched two short-range ballistic missiles from a train.
And three days after that, it launched yet another two ballistic missiles from its capital city, Pyeongyang.
They appeared to be KN-24 missiles, which resemble the U.S. Army Tactical Missile System.
