North Korea fires short-range missiles 250 km from Wonsan after Freedom Edge drills

South Korea's Joint Chiefs of Staff said North Korea fired several short-range ballistic missiles from the Wonsan area at about 5:20 a.m. on Saturday, 12 September. The weapons flew about 250 kilometres and fell into the East Sea, also called the Sea of Japan. No damage was reported on land.

The launch came one day after South Korea, the United States and Japan closed Freedom Edge, a five-day maritime and air exercise held in international waters east and south of Jeju. Seoul's presidential National Security Office called an emergency meeting of the defence ministry, the Joint Chiefs and other agencies. It described the firing as a serious breach of United Nations Security Council resolutions and told Pyongyang to stop.

U.S. Pacific Command said it was aware of the launches and was consulting allies. The Joint Chiefs said South Korean and U.S. intelligence tracked the activity from the start and shared the data with Japan. Surveillance was raised for further firings. The three capitals said they were holding a combined readiness posture.

What flew, and from where

Wonsan sits on North Korea's east coast and has been used before as a short-range launch point. Seoul has not yet named the missile type. A flight of 250 km sits inside the short-range class, which generally covers 300 to 1,000 km depending on the definition used. Analysts have asked whether the salvo involved a Hwasong-11 family system, including the large-calibre KN-25 rocket that Pyongyang used in August. The Joint Chiefs said a detailed technical analysis is still under way.

This was the first ballistic firing in 23 days. On 20 August, North Korea sent about ten short-range ballistic missiles, assessed as 600 mm KN-25 rockets, from the Pyongyang area into the East Sea. Earlier in August a missile from Wonsan flew about 700 km. Saturday's shorter hop looks more like a signalling shot than a maximum-range test.

Drills that Pyongyang treats as the target

Freedom Edge began on 7 September and ended on 11 September. It is the fourth multi-day trilateral run since June 2024. The stated aim is to practise against regional missile and nuclear threats, including North Korea's. The exercise went ahead even after President Donald Trump ordered a cut in the separate Ulchi Freedom Shield drills last month. Trump called those drills costly and a hostile signal to Pyongyang, and he has said he expects to meet Kim Jong Un later this year.

That mix of reduced bilateral drills and a completed trilateral one leaves an awkward message. Washington is trying to keep a door open to talks. Seoul and Tokyo still want visible combined training. Pyongyang answered the week of flying and sailing near Jeju with a morning salvo from Wonsan.

The timing also sits in front of a planned meeting between Trump and Chinese President Xi Jinping in Washington later this month. North Korea is expected to be on that agenda. Kim has spent the past year tightening ties with Beijing and Moscow. A short-range test does not change the nuclear inventory. It does remind the three capitals that Pyongyang can fire on a timetable of its own while leaders talk about summits.

What the numbers do and do not show

Several missiles, not one, left Wonsan. Range of about 250 km keeps the impact area well short of Japan. The Joint Chiefs have not published apogee, interval between shots, or whether the weapons used solid fuel. Those details matter for identifying the system and for judging whether the test practised a salvo against ports or airfields in South Korea.

Cheong Wa Dae, as some Korean outlets still call the presidential office in shorthand, denounced the launch as a resolution breach. That legal line is familiar. What is newer is the political setting: a U.S. president who has publicly cut drills to court Kim, a South Korean government that still wants the trilateral habit, and a North Korean leadership that treats any large exercise as a pretext.

Last month Pyongyang also ordered its forces to stay at full readiness during the scaled-back U.S.-South Korea programme. Saturday's firing fits that pattern of answering exercises with hardware rather than with a statement alone.

The open question in Seoul is whether this salvo is the last word for the week or the first of a short series. The Joint Chiefs said they are watching for more. For now the recorded facts are narrow and solid: several short-range ballistic missiles, Wonsan, 5:20 a.m., about 250 km, East Sea, one day after Freedom Edge shut down.
