South Korea's Joint Chiefs of Staff said North Korea is presumed to have fired one short-range missile from its inland Jagang-do , Mupyong-ri area in an easterly direction at 6:40AM on Tuesday.
This area is where the North test-fired inter-continental ballistic missiles in 2017.
"The ministry is monitoring the situation as well as the motive behind North Korea's missile launch. The launch is regrettable since it was carried out during times when security stability on the Korean Peninsula is critical."
The recent launch is seen as yet another provocation less than two weeks after the North test-fired long-range cruise missiles and modified versions of its KN-23 Iskander-class ballistic missile from a train.
This is also North Korea's sixth military provocation this year.
The launch came three days after Kim Yo-jong, sister of North Korean leader Kim Jong-un, said that the North could declare a formal end to the Korean War as suggested by the South and even discuss the possibility of a summit on the condition that Seoul drops its double standards and hostile attitudes toward the regime.
This comes as the North attempts to see whether South Korea will denounce the launch following the warning about the double standards of criticizing the North while others conduct weapons tests without such criticism.
Observers say it's a tactic used to sour inter-Korean relations in order to gain the upper hand in future negotiations and dramatically reconnect the two Koreas' direct communications line before making a conciliatory gesture when it sees that the timing is right which is when South Korea and the U.S. make some concessions.
