South Korea's military reported that one of the two North Korean ballistic missiles launched possibly flew abnormally. This launch occurred just a day after Pyongyang accused the United States, South Korea, and Japan of forming an "Asian NATO."

North Korea has launched two ballistic missiles, according to the South Korean military on Monday, amidst warnings from Pyongyang regarding a joint military drill. The missiles originated from South Hwanghae Province, flying distances of approximately 600 kilometers (372 miles) and 120 kilometers respectively, as reported by South Korean news agency Yonhap citing Seoul authorities.

In response, a military spokesperson stated in a press conference that South Korea will maintain readiness to respond decisively to any provocation, closely monitoring North Korea's activities within a robust South Korea-US defense posture.

Pyongyang's state-controlled KCNA news agency described the launch as a successful test of "new important technology." However, a South Korean Joint Chiefs of Staff spokesman noted that one missile had exploded during its early flight phase.

Seoul continues to analyze the launch for further details, including any potential casualties or damage to North Korean property. The launch occurred shortly after North Korea criticized a recent joint military exercise involving South Korea, Japan, and the United States, labeling the alliance as "the Asian version of NATO."

In response to the joint exercise, Pyongyang vowed through KCNA to defend its sovereignty, security, and regional peace with "offensive and overwhelming countermeasures."

Under the leadership of Kim Jong Un, North Korea has persisted in developing nuclear-capable missiles despite facing international sanctions over its nuclear weapons and missile programs. South Korean officials suggest that North Korea's recent short-range ballistic missile launches may serve to showcase its military capabilities to potential buyers.

Despite allegations of military cooperation, North Korea and Russia deny claims that Pyongyang supplies ballistic missiles and artillery shells to Moscow, despite their declared mutual military support.
