N.Korea fires salvo of missiles, including ICBM, hours after Biden leaves Asia

North Korea fired three missiles, including one thought to be an intercontinental ballistic missile (ICBM) on Wednesday, after U.S. President Joe Biden left Asia following a trip in which he agreed to new measures to deter the nuclear-armed state.
South Korea’s Joint Chiefs of Staff (JCS) said the three missiles were fired in less than an hour from the Sunan area of the North’s capital, Pyongyang, where its international airport has become a hub of missile tests.
The first missile launched on Wednesday appeared to be an ICBM, while a second unidentified missile appears to have failed mid-flight, the JCS said. The third missile was a short-range ballistic missile (SRBM), it said.
In response, the United States and South Korea held combined live-fire drills, including surface-to-surface missile tests involving the Army Tactical Missile System (ATACMS) of the U.S. and the South’s Hyunmoo-2 SRBM, both militaries said.
“Our military’s show of force was intended to highlight our resolve to firmly respond to any North Korean provocations, including an ICBM launch, and our overwhelming capability and readiness to conduct a surgical strike on the origin of the provocation,” the JCS said in a statement.
North Korea has conducted a flurry of missile launches this year, from hypersonic weapons to test firing its largest ICBMs for the first time in nearly five years. It also appears to be preparing for what would be its first nuclear test since 2017.
U.S. and South Korean officials had recently warned that North Korea appeared ready for another weapons test, possibly during Biden’s visit, which was his first trip to Asia as president and included a summit with South Korean President Yoon Suk-yeol in Seoul.
Yoon, who took office on May 10, convened his first meeting of the national security council, which strongly condemned the latest launch as a “grave provocation”, especially as it came before Biden returned home.
Yoon ordered the aides to strengthen the U.S. extended deterrence and combined defence posture as agreed with Biden, his office said.
“North Korea’s continued provocations will only result in even stronger, faster South Korea-U.S. deterrence, and bring deeper isolation upon itself,” Yoon’s government said in a separate statement.
A White House official said that Biden, who departed Japan on Tuesday evening, had been briefed on the launches and would continue to receive updates.
South Korean Foreign Minister Park Jin and U.S. Secretary of State Antony Blinken also agreed to step up diplomatic efforts to reinforce extended deterrence and facilitate a new U.N. sanctions resolution in a phone call, Seoul’s ministry said.
“We call on the DPRK to refrain from further provocations and engage in sustained and substantive dialogue,” a State Department spokesperson said, using the initials of North Korea’s official name.
SHOW OF FORCE
Pyongyang resumed ICBM testing in late March, ending its self-imposed 2017 moratorium on long-range missile and nuclear testing, amid stalled denuclearisation talks with Washington.
In Wednesday’s test, the suspected ICBM flew 360 km (223.7 miles) to a maximum altitude of 540 km, while the SRBM flew 760 km to a maximum altitude of 60 km, the JCS said.
Japan reported at least two launches, one of which flew about 300 km and reached a maximum altitude of 550 km, and the other to the distance of about 750 km (465 miles) and a maximum altitude of 50 km, Japan’s defence minister said.
Japanese broadcaster NHK said the missiles appeared to have fallen outside Japan’s exclusive economic zone (EEZ).
Japanese chief cabinet secretary Hirokazu Matsuno said the North could take more provocative actions, including a nuclear test.
The U.S. military’s Indo-Pacific Command said it was aware of “multiple” launches. They highlighted the “destabilising impact of the DPRK’s illicit weapons programme” but did not pose an immediate threat.
In Seoul over the weekend, Biden and Yoon agreed to hold bigger military drills and deploy more U.S. strategic assets if necessary to deter North Korea’s intensifying weapons tests.
But they also offered to send COVID-19 vaccines to North Korea as the isolated country battles its first confirmed outbreak, and called on Pyongyang to return to diplomacy.
There had been no response from Pyongyang to the diplomatic overtures or offers of aid, Biden said at the time.
The waning hours of Biden’s visit to the region also saw Russian and Chinese bombers flying joint patrols near Japanese and South Korea air defence zones on Tuesday in a pointed farewell.

‘Massive cyberattack’ brings down Elon Musk’s X
Digital Trends reported Tuesday that there are reports suggesting X is still having issues

Social media platform X went down intermittently on Monday, with owner Elon Musk blaming an unusually powerful cyberattack.
“We get attacked every day, but this was done with a lot of resources. Either a large, coordinated group and/or a country is involved,” Musk said in a post on X on Monday.
He did not clarify exactly what he meant by “a lot of resources” and his comments drew skepticism from cybersecurity specialists, who pointed out that attacks of this nature — called denials of service — have repeatedly been executed by small groups or individuals.
X faced intermittent outages, according to Downdetector, Reuters reported.
Digital Trends meanwhile reported Tuesday that there are reports suggesting X is still having issues.
Internet industry experts have said X was hit by several waves of ‘denial of service’ throughout Monday.
Musk said in an interview with Fox Business Network’s Larry Kudlow the cyberattack came from IP addresses originating in the Ukraine area.
An industry source told Reuters he disputed Musk’s account, saying that large chunks of the rogue traffic bombarding X could be traced back to IP addresses in the United States, Vietnam, Brazil and other countries, and that the amount of rogue traffic coming directly from Ukraine was “insignificant.”
In any case, denial of service attacks are notoriously hard to trace back to their authors and the IP addresses involved rarely provide any meaningful insight into who was behind them, Reuters reported.
Musk has joined U.S. President Donald Trump, whom he serves as an adviser, in criticizing Ukraine’s continued efforts to fight off a Russian invasion.
Musk said on Sunday that Ukraine’s front line “would collapse” without his Starlink satellite communications service, though he said he would not cut off Ukraine’s access to it.

NASA says ‘city killer’ asteroid has a 3.1 % chance of striking Earth in 2032
Despite the rising odds, experts say there is no need for alarm

An asteroid that could level a city now has a 3.1-percent chance of striking Earth in 2032, according to NASA data released Tuesday — making it the most threatening space rock ever recorded by modern forecasting.
Despite the rising odds, experts say there is no need for alarm. The global astronomical community is closely monitoring the situation and the James Webb Space Telescope is set to fix its gaze on the object, known as 2024 YR4, next month.
“I’m not panicking,” Bruce Betts, chief scientist for the nonprofit Planetary Society told AFP.
“Naturally when you see the percentages go up, it doesn’t make you feel warm and fuzzy and good,” he added, but explained that as astronomers gather more data, the probability will likely edge up before rapidly dropping to zero.
2024 YR4 was first detected on December 27 last year by the El Sauce Observatory in Chile.
Astronomers estimate its size to be between 130 and 300 feet (40–90 meters) wide, based on its brightness. Analysis of its light signatures suggests it has a fairly typical composition, rather than being a rare metal-rich asteroid.
The International Asteroid Warning Network (IAWN), a worldwide planetary defense collaboration, issued a warning memo on January 29 after the impact probability had crossed one percent. Since then, the figure has fluctuated but continues to trend upward.
NASA’s latest calculations estimate the impact probability at 3.1 percent, up from 1.6 percent last month, with a potential Earth impact date of December 22, 2032.
Richard Moissl, head of the European Space Agency’s planetary defense office, which puts the risk slightly lower at 2.8 percent told AFP that this “is not a crisis at this point in time. This is not the dinosaur killer. This is not the planet killer. This is at most dangerous for a city.”
If the risk rises over 10 percent, IAWN would issue a formal warning, leading to a “recommendation for all UN members who have territories in potentially threatened areas to start terrestrial preparedness,” explained Moissl.
Unlike the six-mile-wide (10-kilometer-wide) asteroid that wiped out the dinosaurs 66 million years ago, 2024 YR4 is classified as a “city killer” — not a global catastrophe, but still capable of causing significant destruction.
Its potential devastation comes less from its size and more from its velocity, which could be nearly 40,000 miles per hour if it hits.
If it enters Earth’s atmosphere, the most likely scenario is an airburst, meaning it would explode midair with a force of approximately eight megatons of TNT — more than 500 times the power of the Hiroshima bomb.
But an impact crater cannot be ruled out if the size is closer to the higher end of estimates, said Betts.
The potential impact corridor spans the eastern Pacific, northern South America, the Atlantic, Africa, the Arabian Peninsula, and South Asia — though Moissl emphasized it is far too early for people to consider drastic decisions like relocation.
The good news: there’s ample time to act.
NASA’s 2022 DART mission proved that spacecraft can successfully alter an asteroid’s path, and scientists have theorized other methods, such as using lasers to create thrust by vaporizing part of the surface, pulling it off course with a spacecraft’s gravity, or even using nuclear explosions as a last resort. — Agence France-Presse
