North Korea launched a ballistic missile from the Wonsan area toward the sea on Saturday, October 3, 2026, as tensions with South Korea and Japan intensified over a deadly border-mine blast.
South Korea’s Joint Chiefs of Staff said the missile was detected at about 6:30 a.m. local time and traveled more than 700 kilometers before falling into the East Sea, also known as the Sea of Japan. Seoul and Washington were analyzing the weapon’s precise type and characteristics, while South Korea increased surveillance for possible additional launches. Japan issued an emergency warning and said the object was believed to have been a ballistic missile, while authorities advised ships to take precautions.
South Korea, the United States and Japan continued sharing information and maintaining a heightened defense posture after the launch. Seoul’s national security officials also convened an emergency meeting to assess the implications of the test. The launch followed a September 21 mine explosion in the Demilitarized Zone that injured three South Korean soldiers, an incident Seoul has blamed on North Korean mines.
Pyongyang has denied responsibility and rejected Seoul’s demand for an apology, further worsening already strained inter-Korean relations.
