North Korea fired a ballistic missile toward the East Sea early Saturday morning, according to South Korea's Joint Chiefs of Staff. The launch occurred around 6:30 a.m. local time from the Wonsan area and flew more than 700 kilometers before landing at sea.

South Korean and U.S. forces are analyzing the missile's exact specifications. Japanese officials estimated a similar range of about 680 kilometers and confirmed it landed outside Japan's exclusive economic zone.

Pyongyang later described the event as a drill involving an intermediate-range strategic missile. Kim Yo-jong, the influential sister of leader Kim Jong-un, stated that Kim Jong-un oversaw the test conducted by a special firepower unit. She mocked South Korean and Japanese tracking estimates, claiming the missile used a wave-like trajectory that caused opponents to lose the target.

The launch marks North Korea's 15th ballistic missile test this year and comes 13 days after its previous firings on September 20. It follows heightened tensions over a September 21 incident in the Demilitarized Zone, where North Korean land mines injured three South Korean soldiers.

Pyongyang rejected South Korea's demand for an apology over the mines, with Kim Yo-jong dismissing the claims and reiterating that the North seeks to sever all ties with the South.

South Korea's presidential national security office convened an emergency meeting and urged North Korea to halt its launches, calling them violations of U.N. Security Council resolutions. The U.S. Indo-Pacific Command said the test posed no immediate threat to American personnel or allies but reaffirmed commitments to regional defense.

South Korea, the United States, and Japan continue to share intelligence and maintain heightened monitoring for additional activity.
