SEOUL – North Korea fired two short-range ballistic missiles off its east coast on Thursday, the South Korean military said.
The missiles were launched less than an hour after North Korea warned of an inevitable response to live fire drills carried out by South Korea together with the United States.
The latest action by Pyongyang came as US President Joe Bidens national security adviser Jake Sullivan was in Tokyo for meetings with his Japanese and South Korean counterparts.
At the meeting with South Koreas national security adviser Cho Tae-yong and Japans National Security Advisor Takeo Akiba on Thursday, the three discussed North Koreas missile programme.
The three advisers confirmed they would work closely together to get Pyongyang to abandon its nuclear weapons, according to a readout of the meeting released by Japan.
The Japanese defence ministry said the two ballistic missiles landed within the countrys exclusive economic zone, possibly having flown in an irregular trajectory.
One landed in the Sea of Japan which is also known as the East Sea about 110km north-west of Hegura island, part of Ishikawa prefecture.
The other landed about 250km away, the Japanese authorities said.
South Korean President Yoon Suk-yeol watched as several thousand South Korean and US troops took part in joint live-fire exercises on Thursday.
The drills were a show of force after North Koreas failed attempt to launch a spy satellite last month heightened tensions in the region.
A spokesman for North Koreas Ministry of National Defence said the drills were escalating the military tension in the region and its forces would sternly respond to any kind of protests or provocations by enemies.
Pyongyang unsuccessfully tried to launch a spy satellite late last month, in its first such attempt since 2016, with the rocket booster and payload plunging into the sea.
North Koreas ballistic missile and nuclear weapons programmes are banned by United Nations Security Council resolutions that have sanctioned the country.
Diplomatic efforts to reduce tensions or persuade Pyongyang to abandon its nuclear arsenal have been stalled.
South Korea sued North Korea on Wednesday for US$35 million (S$47 million) in compensation for a liaison office that North Korea blew up in 2020, in a case highlighting the breakdown of ties between the neighbours as the North presses on with its weapons programmes.
Pyongyang has already fired 17 ballistic missiles so far this year, which included three intercontinental ballistic missiles designed to deliver a nuclear warhead to the US mainland.
The country fired off more than 70 ballistic missiles last year, a record for the state. REUTERS, BLOOMBERG More On This Topic Japan and South Korea to speed up talks over pending military issues North Koreas space satellite crashes into sea; alerts sent and then retracted in South Korea, Japan
A long-hidden plume of magma beneath Oman’s Salma Plateau may have played a surprising role in shaping the Indian subcontinent’s ancient journey, researchers report. This “ghost” plume — hot material trapped beneath Earth’s thick crust — cannot erupt but may have shifted the Indian tectonic plate’s course during its dramatic collision with Eurasia tens of millions of years ago. First detailed in the journal Earth and Planetary Science Letters, the finding reveals a new class of deep mantle plumes that shape continents silently, without the typical signature of surface volcanoes.
Hidden ‘Ghost’ Plume Beneath Oman May Have Steered India’s Collision Path with Eurasia
As per a Live Science report, the plume was detected using seismic data from Oman’s dense sensor network. Under the leadership of geophysicist Simone Pilia, the group discovered that the plume altered the way sound waves moved through Earth’s layers, which in turn pointed to its presence. Unlike most mantle plumes, which rise and erupt through the oceanic plates, Dani is amagmatic and does not create surface eruptions because of the thick continental crust above the plume. This finding means that there may potentially be many hidden plumes lurking beneath continents.
The Dani plume is the first such non-eruptive plume beneath a continental plate, which is broadening scientists’ view of how mantle dynamics unfold out of sight. The researchers also calculated the movement of the Indian plate and found that it took a significant turn between 40 and 25 million years ago, which might have been affected by the shear stress created by the plume. The plume’s effects on topography are expected to be small regionally, but its geological role could be relatively large.
While plumes typically leave a visible volcanic trail—like Hawaii’s island chain—the Dani plume’s evidence may have been erased by subduction activity in the nearby Makran zone. Still, researchers say this finding opens the door to discovering more “ghost” plumes, particularly in regions with similar thick crusts, such as Africa. As seismic technologies advance, more silent subterranean forces shaping Earth’s history may come to light.
Iran claims it has carried out a “mighty and successful response” to “America’s aggression” after launching missile attacks on a US military base in Qatar and Iraq.
Iran’s response this evening is the latest escalation in tensions in the volatile region.
Qatar has said there were no casualties at the al Udeid base following the strikes and that its “air defences thwarted the attack and successfully intercepted the Iranian missiles”.
People in Qatar’s capital, Doha, had stopped and gazed up at the sky as missiles flew and interceptors fired.
Iran had announced on state television that it had attacked American forces stationed at the al Udeid airbase.

Iran releases video after attack on US base
Initial reports claimed Iran had also targeted a base housing US troops in western Iraq, but a US military official later told Reuters news agency the attack in Qatar was the only one detected.
A US government official said the White House and US defence department was “closely monitoring” the potential threats to its base.
Meanwhile, US President Donald Trump was in the Situation Room in the White House with his team following the Iranian strikes.

He later said in a post on Truth Social that the missiles were a “very weak response”, which the US “expected” and “very effectively countered”.
He added: “Most importantly, they’ve gotten it all out of their ‘system,’ and there will, hopefully, be no further HATE.
“I want to thank Iran for giving us early notice, which made it possible for no lives to be lost, and nobody to be injured.
“Perhaps Iran can now proceed to Peace and Harmony in the Region, and I will enthusiastically encourage Israel to do the same.”
Iran’s Supreme Leader Ayatollah Ali Khamenei said in a post on X: “We have not violated anyone’s rights, nor will we ever accept anyone violating ours, and we will not surrender to anyone’s violation; this is the logic of the Iranian nation.”
The attacks came shortly after Qatar closed its airspace as a precaution amid threats from Iran.
Just before the explosions, Iranian president Masoud Pezeshkian wrote on the social platform X: “We neither initiated the war nor seeking it. But we will not leave invasion to the great Iran without answer.”
Kuwait and Bahrain briefly shut their airspaces after the attack, news agencies in each country reported.
Iraq also shut its airspace, while Oman Air suspended some flights in the region.
The Abu Dhabi-based Etihad Airways said it is rerouting several flights today and tomorrow due to restrictions in parts of the Middle East.
Three of Iran’s key nuclear enrichment facilities – Fordow, Natanz and Isfahan – were targeted in US airstrikes on 22 June.
The prime target of the attacks was Iran’s most advanced facility at Fordow, suspected of being used to enrich uranium close to what’s needed for a nuclear bomb.
Satellite images from the aftermath of the US strikes suggest at least six bombs were dropped there.

The secure nuclear facility, home to Iran’s main enrichment site, is buried deep under a mountain.
So exactly how much damage was done is unknown, perhaps even to Iran, which appears to have evacuated the site. The specific location of the strikes and the bombs used gives us an indication.
America used the 30,000-lb Massive Ordnance Penetrator bomb, or a GBU-57 – commonly known as a “bunker buster”.
The bunker buster is the only missile that had a chance of destroying the Fordow facility, and American planes were needed for them to be used.

Blueprints from Iran’s Nuclear Archive, which date from before 2004 and were seized by Israeli spies in 2018, suggest the bombs targeted the tunnels under the Fordow site.

The access tunnels overground lead to a 250 metre long hall which is thought to contain the uranium enrichment centrifuges, and well as the location of what is thought to be ventilation shafts.
Iran is thought to have likely moved any enriched uranium from the facility before the strikes occurred. But if the ventilation shafts were hit, that would allow the bombs to penetrate as far as possible and hit the centrifuge hall itself.
Iran’s major nuclear facilities seriously damaged, if not completely destroyed
The loss of industrial-scale centrifuge “cascades” used to enrich uranium will certainly derail any imminent deadlines in weaponisation the Islamic Republic may have set itself – more on that below.
But it has already amassed a sizeable stockpile of highly enriched uranium and may even have already enriched some of it to the 90% or so needed to make fissile material necessary for a bomb.
And despite strikes on industrial scale facilities that have taken decades to generate that stockpile, the material itself weighs less than half a tonne.
Moving it, splitting it up, concealing it, is not beyond the wit of a nation that expected these assaults may be coming.
Iran’s nuclear programme is also more than its large-scale facilities. Iran has been developing nuclear expertise and industrial processes for decades. It would take more than a concerted bombing campaign to wipe that out.
The final steps to “weaponise” highly enriched uranium are technically challenging, but Iran was known to be working on them more than 20 years ago.
Iran also does not require industrial-scale facilities like those needed to enrich uranium, meaning they could be more easily concealed in a network of smaller, discrete lab-sized buildings.
But what’s far from clear is whether Iran had actually taken steps towards weaponisation in recent years.
Recent US intelligence assessments indicated that it hadn’t. Iran’s leaders knew that very significant moves towards making a bomb would be seen as a major escalation by its neighbours and the international community.
For a long time, a key deterrent to Iran developing a nuclear weapon has been an internal political one.
It’s possible of course that position may have been shifting and these latest strikes were designed to disarm a rapidly weaponising Iran.
But it’s also possible the attacks on its nuclear programme may be forcing a previously tentative government to push harder towards making a nuclear bomb.
Fordow is only one of three nuclear facilities targeted in America’s strike, however, and one of seven that have been targeted since the conflict began.
Natanz’s uranium enrichment facility, about 140 km south of Fordow, had been subject to multiple Israeli strikes before America’s advance.

Israeli raids targeted surface buildings, including stores of enriched uranium. However, post-strike radiation monitoring suggested there was little, if any, nuclear material there.
At the weekend, Americans dropped bunker-buster bombs there too, targeting thousands of enrichment centrifuges operating in bunkers below.

Then there is the Isfahan complex. Again, Israeli missiles destroyed a number of buildings there last week. And at the weekend, US cruise missiles targeted others, including the uranium conversion plant.
At the weekend, Americans also dropped bunker-buster bombs there, targeting thousands of enrichment centrifuges operating in bunkers below.

Speaking from the White House after the attacks, Donald Trump said facilities had been “completely and totally obliterated”. But experts suggest it could take more to destroy it entirely.
“This is a very well-developed, long-standing programme with a lot of latent expertise in the country,” said Darya Dolzikova, a proliferation and nuclear security expert at RUSI, a UK defence and security thinktank
“I don’t think we’re talking about a full elimination at this point, certainly not by military means.”
