North Korea fires missiles as row over landmine blast intensifies

The brief

North Korea launched about 10 short-range ballistic missiles, according to South Korea’s Joint Chiefs of Staff. The missiles headed eastward into the Sea of Japan. The launch mattered because it came during a sharp dispute with South Korea over a landmine explosion and less than a week after Seoul proposed military talks. The missiles were fired at about 12:30pm, or 03:30 GMT, on Thursday. The launch site was an area around Wonsan, on North Korea’s eastern coast. Japan’s Defence Ministry separately confirmed what it said could be a ballistic missile launch. The missiles fell outside Japan’s Exclusive Economic Zone, according to Tokyo-based Kyodo News. The article does not give their exact travel distance or individual impact locations. The launch added to border tensions while North Korea rejected Seoul’s accusation over the landmines and warned that sovereignty violations could trigger self-defence.

What exactly happened in the latest incident, and where did North Korea launch the missiles?

North Korea launched about 10 short-range ballistic missiles, according to South Korea’s Joint Chiefs of Staff. The missiles headed eastward into the Sea of Japan. The launch mattered because it came during a sharp dispute with South Korea over a landmine explosion and less than a week after Seoul proposed military talks.

The missiles were fired at about 12:30pm, or 03:30 GMT, on Thursday. The launch site was an area around Wonsan, on North Korea’s eastern coast. Japan’s Defence Ministry separately confirmed what it said could be a ballistic missile launch.

The missiles fell outside Japan’s Exclusive Economic Zone, according to Tokyo-based Kyodo News. The article does not give their exact travel distance or individual impact locations. The launch added to border tensions while North Korea rejected Seoul’s accusation over the landmines and warned that sovereignty violations could trigger self-defence.

02

What is a short-range ballistic missile, and how does it differ from a long-range missile?

A short-range ballistic missile is a rocket-powered weapon that follows a high, arcing flight path before descending toward its target. “Short-range” means its reach is limited compared with medium-, intermediate-, or long-range missiles. This distinction matters because range affects which countries or military sites a missile can threaten.

After launch, the missile gains speed and climbs. It then travels along a ballistic path, with gravity drawing it down toward the target. A long-range missile uses the same broad idea but is built to travel much farther, often across regions or continents. Exact categories can vary by definition.

In this incident, South Korea described the weapons as short-range ballistic missiles. The article reports about 10 launches from near Wonsan and says they fell outside Japan’s Exclusive Economic Zone. It does not provide their technical range, speed, warhead, or individual flight paths.

03

How many missiles were fired, how far could they travel, and where did they land?

The latest launch involved about 10 short-range ballistic missiles. That number came from South Korea’s Joint Chiefs of Staff. The scale signaled renewed military activity at a sensitive moment, when Seoul and Pyongyang were already disputing a landmine explosion near their border.

The missiles were launched around 12:30pm Thursday, or 03:30 GMT, from near Wonsan on North Korea’s east coast. Japan’s Defence Ministry separately confirmed what it said could be a ballistic missile. The article does not state how far each missile traveled or provide a maximum range.

The reported landing area was the Sea of Japan. Japan’s Defence Ministry said the missile fell outside the country’s Exclusive Economic Zone. The report does not identify separate impact points, exact distances, or whether all 10 missiles landed in precisely the same area. Those missing details limit a more exact assessment of the launch.

04

What is the Demilitarized Zone, and why is it one of the most heavily fortified borders in the world?

The Demilitarized Zone is the heavily fortified border between North Korea and South Korea. Despite its name, it is not simply an empty or peaceful space. The article presents it as a frontline area where military activity and disputes can quickly raise tensions across the Korean peninsula.

The immediate example is a landmine explosion in the DMZ on September 21. Three South Korean soldiers were injured. A joint South Korea-United Nations investigation concluded that North Korea had planted the mines more than a year earlier. Pyongyang rejected that finding and accused Seoul of fabricating the incident.

The border’s importance is clear in the response. South Korea demanded an apology and proposed talks to restore communication channels. North Korea warned that alleged violations of its sovereignty could trigger self-defence. The missile launch followed as military activity near the border increased, making the DMZ a focus of both security fears and diplomatic pressure.

05

How did the landmine explosion, the competing claims about responsibility, and demands for an apology intensify tensions?

The landmine explosion intensified tensions because it caused direct injuries and produced sharply opposed accounts of responsibility. Three South Korean soldiers were hurt in the Demilitarized Zone on September 21. A joint South Korea-United Nations investigation later concluded that North Korea had planted the mines more than a year earlier.

South Korea called for an apology. North Korea rejected the investigation and sent a letter to the UN Security Council accusing Seoul of fabricating the explosion. Kim Song called Seoul’s attempt to shift blame a provocation and said violations of North Korea’s sovereignty could trigger self-defence. Kim Yo Jong called the apology demand despicable.

The competing claims blocked a shared account of what happened. They also raised the political cost of backing down. South Korea proposed military talks and communication channels, while North Korea maintained a hardline approach. The missile launch added a visible military signal to an already escalating dispute.

06

Why is South Korea proposing military talks and the restoration of communication channels with North Korea?

South Korea proposed military talks because tensions were rising along the border. Seoul wanted to discuss restoring communication channels with Pyongyang. Such channels can provide a way to deliver warnings, clarify actions, and address incidents before they lead to further confrontation. The article does not say that talks had been accepted.

The proposal followed the landmine explosion that injured three South Korean soldiers. Seoul backed a joint South Korea-United Nations finding that North Korea had planted the mines and demanded an apology. Pyongyang rejected the finding and accused Seoul of fabricating the incident. Military activity near the border was also increasing.

The offer therefore served both immediate and broader purposes. It sought to calm the dispute and reopen a practical link between the two militaries. The outlook remained uncertain because North Korea had suspended virtually all dialogue and cooperation with the South in recent years. Its hardline approach made agreement unclear.

07

How do military threats and missile tests function as deterrence in the unresolved conflict between North and South Korea?

Deterrence means trying to prevent an opponent from taking an unwanted action by showing the ability and willingness to respond. Missile tests can support that message by demonstrating military readiness. In an unresolved conflict, they may also be used to gain attention, pressure an opponent, or signal displeasure without immediately starting a larger attack.

Here, North Korea fired about 10 short-range ballistic missiles while tensions over the DMZ landmine explosion were rising. Pyongyang rejected Seoul’s accusations and warned that violations of its sovereignty could trigger self-defence. The launch therefore communicated military capability alongside diplomatic warnings, although the article does not state North Korea’s precise intention.

Deterrence can reduce the chance of direct attack when both sides fear escalation. It can also increase danger if each side interprets demonstrations as preparation for aggression. South Korea sought talks and restored communication channels, but North Korea’s hardline stance and the missile launches showed that military signaling remained central to the relationship.
