On the day South Korean President Yoon Suk-yeol marked his first 100 days in office, North Korea on Wednesday morning fired two cruise missiles towards the West Sea.
A South Korean military official said the missiles were fired from the North's west coast town of Onchon, without providing further details.
This was the first missile launch from the North in more than two months, since they fired a ballistic missile on June 5th.
The launch also come as Seoul and Washington hold four days of preliminary drills, in preparation for their major combined training that has infuriated Pyeongyang.
Named the "Ulchi Freedom Shield" the summertime drill will involve live field exercises for the first time in four years and will be held in South Korea from next Monday through September 1st.
South Korea's presidential office said its national security adviser held a meeting after Wednesday's launch, to assess the security situation and examine the military's readiness.
Since 2020, North Korea has reportedly test-fired cruise missiles around ten times.
And in January last year, it announced that it's planning to develop advanced cruise missiles.
The regime recently claimed to have developed two types of new cruise missiles, and unveiled them through their defense development exhibition and military parade.
"Test-firing the missiles around 10 times was probably not enough for them to perfectly develop new types of weapons system. So it seems the latest launch was made because of a number of reasons to test their new missiles and to criticize the combined training between South Korea and Japan."
Cruise missile can be seen as a rather low-level provocation, as most cruise missiles are not designed to carry nuclear warheads.
But one expert notes there's a possibility of stronger actions from the North during the combined training period.
"If they are planning something stronger, we cannot rule out the possibility of the North launching its new ballistic missile, or even ditching the military agreement."
