SEOUL: A second reactor at North Korea’s Yongbyon nuclear facility appears to be operational, according to the UN atomic agency.
Yongbyon is North Korea’s main nuclear complex and home to its first nuclear reactor, with a five megawatt capacity, and has been the only known source of plutonium for its weapons program.
A second one — a light-water reactor — now also appears to be operational, based on observations that warm water is being discharged from it, the International Atomic Energy Agency said in a statement released late on Thursday.
“The discharge of warm water is indicative the reactor has reached criticality,” IAEA Director General Rafael Mariano Grossi said in a statement.
In the operation of a nuclear reactor, criticality is the state in which a nuclear chain reaction is self-sustaining, according to experts.
Since North Korea expelled its inspectors in 2009, the IAEA has been denied access to the country.
The agency has since been primarily relying on satellite imagery to monitor the North.
“Without access to the facility the Agency cannot confirm its operational status,” Grossi said.
He emphasised that “construction and operation” of the light-water reactor (LWR) was against the United Nations Security Council resolutions and “deeply regrettable.”
“The LWR, like any nuclear reactor, can produce plutonium in its irradiated fuel, which can be separated during reprocessing, so this is a cause for concern,” Grossi said.
Plutonium, which is a primary material for nuclear weapons, is believed to be extracted through the reprocessing of spent fuel rods produced during the operation of the first nuclear reactor at Yongbyon.
Kim Dong-jin, a researcher at the Korea Atomic Energy Research Institute, confirmed to AFP that warm water discharge would indicate any reactor was operational.
“Warm water discharge is a common occurrence in operating light water reactors,” Kim said.
“During the operation of a power plant, it is necessary to circulate cooling water. As a result, the water is heated.”
South Korea’s Yonhap news agency also reported that the IAEA statement suggested that a “larger light-water reactor” has begun operation at Yongbyon.
North Korea conducted its first nuclear test in 2006, and carried out its sixth and most powerful one in September 2017.
In March this year, Kim called for expanded production of “weapon-grade nuclear materials” as North Korea unveiled what appeared to be a new, smaller tactical nuclear warhead.
The country on Monday launched its solid-fuel Hwasong-18 intercontinental ballistic missile, the largest weapon in its arsenal.
Kim on Thursday also warned through the country’s state media that Pyongyang will not hesitate to launch a nuclear attack if “provoked” with nukes.

China’s US envoy urges end to trade war, but warns Beijing ready to fight

- The trade war has all but frozen the mammoth trade between the world's two largest economies
- Trump said on Friday the U.S. is having good conversations privately with China amid the two countries' trade war.
Speaking at a public event in Washington on Saturday, details of which were posted on the Chinese embassy’s web site, Xie said tariffs would devastate the global economy and drew a parallel between the Great Depression and tariffs imposed by the US in 1930.
Referring to concepts in traditional Chinese medicine like the need to balance the opposing forces of yin and yang, Xie said harmony should guide relations between the world’s two largest economies.
“A good traditional Chinese medicine recipe usually combines many different ingredients which reinforce one another and creates the best medical effect,” he said.
“Likewise, the earth is big enough to accommodate both China and the US,” he said. “We should pursue peaceful coexistence rather than collide head-on, and help each other succeed rather than get caught in a lose-lose scenario.”
The trade war has all but frozen the mammoth trade between the world’s two largest economies with tariffs over 100 percent in each direction and a suite of trade, investment and cultural restrictions.
China’s top shipbuilding association on Saturday attacked a US plan to apply port fees on China-linked ships.
While Japan, Taiwan and others are already in talks or preparing to negotiate with Washington over President Donald Trump’s “Liberation Day” tariffs, there is currently no high-level dialogue planned with China.
Trump said on Friday the US is having good conversations privately with China amid the two countries’ trade war.
“By the way, we have nice conversations going with China,” he told reporters at the White House. “It’s, like, really very good.” He did not offer additional details.
China has said the US should show respect before any talks can take place.
Xie said China opposed the trade war and would retaliate to any country imposing tariffs on it.
Putin attends Orthodox Easter service after declaring ceasefire in Ukraine

- The traditionally sung service starts late on a Saturday and lasts into the early hours of Sunday
- Zelensky says Russian army ‘trying to create impression’ of Easter ceasefire
President Vladimir Putin and Moscow Mayor Sergei Sobyanin joined other worshippers for an Easter service led by the head of Russia’s Orthodox Church, Patriarch Kirill, a faithful backer of the Russian leader and an advocate for the war in Ukraine.
Hours after declaring a unilateral Easter ceasefire that Kyiv said was just words as fighting continued, Putin and Sobyanin stood in Moscow’s main church, the Cathedral of Christ the Savior, while Kirill led a procession, video of the service showed.
Holding a lit thin red candle and donning a dark suit, white shirt and a red tie as in years past, the Russian leader crossed himself several times when Kirill announced “Christ is risen.”
The traditionally sung service starts late on a Saturday and lasts into the early hours of Sunday.
For Putin, the Orthodox faith is central to his world view and he always attends services during major church holidays. For Orthodox Russians, Easter is the most important religious holiday.
At the service, Krill called for “lasting and just peace can be established in the vast expanses of historical Rus,” RIA state news agency reported, in what was a reference to a medieval territory that encompassed parts of what is now Ukraine, Belarus and Russia. “How wonderfully it was said, do not do evil to another and do not treat others as you would not want them to treat you,” TASS agency cited Kirill as saying.
“If people adhered to this holiday commandment, then life would be completely different: family and social life and — let me say this — inter-governmental.”
Kirill has strongly backed the war in Ukraine, now in its fourth year. Thousands have been killed, the vast majority of them Ukrainians, and millions driven from their homes since Putin ordered the invasion of Ukraine in February 2022.
Zelensky says Russian army ‘trying to create impression’ of Easter ceasefire
President Volodymyr Zelensky said on Sunday that the Russian army is making a pretense of an Easter ceasefire declared by President Vladimir Putin, continuing overnight attempts to inflict front-line losses on Ukraine.
“In general, as of Easter morning, we can say that the Russian army is trying to create a general impression of a ceasefire, but in some places it does not abandon individual attempts to advance and inflict losses on Ukraine,” Zelensky said in a post on social media.
Early on Sunday, Ukrainian forces reported 59 instances of shelling and five assault attempts along the front line, he said.
“Russia must fully comply with the conditions of silence,” Zelensky said.
He reiterated that Kyiv was willing to extend the ceasefire for 30 days but said that if Russia kept fighting on Sunday, so would Ukraine.
“Ukraine will continue to act in a mirror manner,” he said.
Zelensky says Ukraine will observe Putin’s Easter truce but claims violations

- The order to halt all combat over the Easter weekend came after months of efforts by US President Donald Trump to get Moscow and Kyiv to agree a ceasefire
KRAMATORSK, Ukraine: Ukraine’s Volodymyr Zelensky said Saturday his forces would observe a surprise Easter truce announced by Russian President Vladimir Putin set to last until midnight on Sunday, even as air-raid sirens sounded in Kyiv.
The 30-hour truce would be the most significant pause in the fighting throughout the three-year conflict.
But just hours after the order was meant to have come into effect, air-raid sirens sounded in the Ukrainian capital and Zelensky accused Russia of having maintained its artillery fire and assaults on the frontline.
Also on Saturday, Russia and Ukraine held a large exchange of prisoners, each side saying they had handed back more than 240 captured fighters.
The order to halt all combat over the Easter weekend came after months of efforts by US President Donald Trump to get Moscow and Kyiv to agree a ceasefire. On Friday, Washington even threatened to withdraw from talks if no progress was made.
“Today from 1800 (1500 GMT Saturday) to midnight Sunday (2100 GMT Sunday), the Russian side announces an Easter truce,” Putin said in televised comments during a meeting with the Russian chief of the general staff Valery Gerasimov.
Zelensky responded by saying Ukraine would follow suit, and proposed extending the truce beyond Sunday. But the Ukrainian leader also accused Russia of having already broken its promises.
Air-raid sirens sounded in Kyiv and several other regions on Saturday evening.
“Russian assault operations continue on several frontline sectors, and Russian artillery fire has not subsided,” Zelensky said.
Putin had said the truce for the Easter holiday celebrated on Sunday was motivated by “humanitarian reasons.”
While he expected Ukraine to comply, he said that Russian troops “must be ready to resist possible breaches of the truce and provocations by the enemy.”
Zelensky in a social media post wrote: “If Russia is now suddenly ready to truly engage in a format of full and unconditional silence, Ukraine will act accordingly — mirroring Russia’s actions.”
He added: “If a complete ceasefire truly takes hold, Ukraine proposes extending it beyond the Easter day of April 20.”
He proposed that “30 days could give peace a chance,” while pointing out that Putin had earlier rejected a proposed 30-day full and unconditional ceasefire.
“The fighting is ongoing, and Russian attacks continue,” Ukraine’s military command, the Chief of Staff, reported Saturday evening.
“In some areas on the frontline, Russian artillery continues to be heard, despite the promise of silence from the Russian leader. Russian drones are being used. It is quieter in some areas.”
Soldiers in the eastern Ukrainian city of Kramatorsk close to the front line earlier greeted the truce announcement with skepticism.
Putin “might do it to give some hope or to show his humanity,” said Dmitry, a 40-year-old soldier. “But either way, of course, we don’t trust (Russia).”
Putin said the latest truce proposal would show “how sincere is the Kyiv’s regime’s readiness, its desire and ability to observe agreements and participate in a process of peace talks.”
Russia launched its full-scale invasion of neighboring Ukraine in February 2022.
Previous attempts at holding ceasefires for Easter in April 2022 and Orthodox Christmas in January 2023 were not implemented after both sides failed to agree on them.
“For millions of Ukrainians, Easter is one of the most important holidays. And millions of Ukrainians will go to church,” said Zelensky in his evening address.
“Over the years of this full-scale war, Russian attacks have destroyed or damaged more than 600 churches, prayer houses and places of worship.”
In Kramatorsk, one soldier, Vladislav, 22, said: “I feel like it’s going to start again after a while, and it’s going to go on and on.”
On the streets of Moscow, Yevgeny Pavlov, 58, said he did not think Russia should give Ukraine a breather.
“There is no need to give them respite. If we press, it means we should press to the end,” he told AFP.
Earlier Saturday, Ukraine and Russia said they had each returned 246 soldiers being held as prisoners of war in a swap mediated by the United Arab Emirates.
Zelensky said the total number of returned POWs now stood at 4,552.
The UAE’s foreign ministry said 31 wounded Ukrainians and 15 wounded Russians were also exchanged.
The UAE said it was committed to “finding a peaceful solution” to the conflict and “mitigating the humanitarian impacts.”
Russia said it had retaken the penultimate village still under Ukrainian control in its Kursk frontier region.
Kyiv had hoped to use its hold on the region as a bargaining chip in the talks.
Three Hegseth aides ousted in leak investigation decry ‘baseless attacks’

- Former Pentagon spokesman John Ullyot also announced he was resigning this week
WASHINGTON: Three former senior advisers to Defense Secretary Pete Hegseth decried on Saturday what they called “baseless attacks” after each was escorted from the Pentagon in an expanding probe on information leaks.
Dan Caldwell, a Hegseth aide; Colin Carroll, chief of staff to Deputy Defense Secretary Stephen Feinberg; and Darin Selnick, Hegseth’s deputy chief of staff were among four officials in Hegseth’s inner circle who were ousted this past week.
While the three initially had been placed on leave pending the investigation, a joint statement shared by Caldwell on X said the three were “incredibly disappointed by the manner in which our service at the Department of Defense ended. Unnamed Pentagon officials have slandered our character with baseless attacks on our way out the door.”
“At this time, we still have not been told what exactly we were investigated for, if there is still an active investigation, or if there was even a real investigation of ‘leaks’ to begin with,” the post said.
Former Pentagon spokesman John Ullyot also announced he was resigning this week. The Pentagon said, however, that Ullyot was asked to resign.
The upheaval comes less than 100 days into the Trump administration where the Pentagon has found itself frequently in the epicenter of controversial moves — from firings of senior military and civilian staff to broad edicts to purge content that promoted diversity, equity or inclusion. That led to images or other online content of heroes like the Tuskegee Airmen and Jackie Robinson being temporarily removed from the military’s websites, causing public uproar.
Last month, Hegseth announced that the Pentagon’s intelligence and law enforcement arms were investigating what it says are leaks of national security information following reports that Elon Musk was set to receive a classified briefing on potential war plans with China.
In the announcement by Hegseth’s chief of staff, Joe Kasper, the office warned that Defense Department personnel could face polygraphs in the probe.
The departures also follow the firings of senior military officers, including Joint Chiefs Chairman Gen. CQ Brown; Chief of Naval Operations Lisa Franchetti; National Security Agency and US Cyber Command director Gen. Tim Haugh; and Vice Adm. Shoshana Chatfield, the US military representative to the NATO Military Committee.
250 years after America went to war for independence, a divided nation battles over its legacy

- Historians can confidently tell us that hundreds of British troops marched from Boston in the early morning of April 19, 1775, and gathered about 14 miles (23 kilometers) northwest, on Lexington’s town green
LEXINGTON, Mass.: Tens of thousands of people came to Lexington, Massachusetts, just before dawn on Saturday to witness a reenactment of how the American Revolution began 250 years ago, with the blast of gunshot and a trail of colonial flair.
Starting with Saturday’s anniversary of the Battles of Lexington and Concord, the country will look back to its war of independence and ask where its legacy stands today. Just after dawn on the Lexington Battle Green, militiamen, muskets in hand, took on a much larger contingent of British regulars. The battle ended with eight Americans killed and 10 wounded — the dead scattered on the grounds as the British marched off.
The regulars would head to Concord but not before a horseman, Dr. Samuel Prescott, rode toward the North Bridge and warned communities along the way that the British were coming. A lone horseman reenacted that ride Saturday, followed by a parade through town and a ceremony at the bridge.
The day offers an opportunity to reflect on this seminal moment in history but also consider what this fight means today. Organizers estimated that over 100,000 came out for events in the two towns Saturday.
“It’s truly momentous,” said Richard Howell, who portrayed Lexington Minute Man Samuel Tidd in the battle.
“This is one of the most sacred pieces of ground in the country, if not the world, because of what it represents,” he said. “To represent what went on that day, how a small town of Lexington was a vortex of so much.”
Among those watching the Lexington reenactment was Brandon Mace, a lieutenant colonel with the Army Reserve whose ancestor Moses Stone was in the Lexington militia.
He said watching the reenactment was “a little emotional.”
“He made the choice just like I made and my brother made, and my son is in the Army as well,” Mace said. .”.. He did not know we would be celebrating him today. He did not know that he was participating in the birth of the nation. He just knew his friends and family were in danger.”
The 250th anniversary comes with President Donald Trump, scholars and others divided over whether to have a yearlong party leading up to July 4, 2026, as Trump has called for, or to balance any celebrations with questions about women, the enslaved and Indigenous people and what their stories reveal.
What happened at Lexington and Concord?
Historians can confidently tell us that hundreds of British troops marched from Boston in the early morning of April 19, 1775, and gathered about 14 miles (23 kilometers) northwest, on Lexington’s town green.
Witnesses remembered some British officers yelled, “Throw down your arms, ye villains, ye rebels!” and that a shot was heard amid the chaos, followed by “scattered fire” from the British. The battle turned so fierce that the area reeked of burning powder. By day’s end, the fighting had moved to about 7 miles (11 kilometers) west to Concord and some 250 British and 95 colonizts were killed or wounded.
But no one knows who fired first, or why. And the revolt itself was initially less a revolution than a demand for better terms.
Woody Holton, a professor of early American history at the University of South Carolina, said most scholars agree that the rebels of April 1775 weren’t looking to leave the empire, but to repair their relationship with King George III and go back to the days before the Stamp Act, the Tea Act and other disputes of the previous decade.
“The colonizts only wanted to turn back the clock to 1763,” he said.
Stacy Schiff, a Pulitzer Prize-winning historian whose books include biographies of Benjamin Franklin and Samuel Adams, said Lexington and Concord “galvanized opinion precisely as the Massachusetts men hoped it would, though still it would be a long road to a vote for independence, which Adams felt should have been declared on 20 April 1775.”
But at the time, Schiff added, “It did not seem possible that a mother country and her colony had actually come to blows.”
A fight for the ages
The rebels already believed their cause was bigger than a disagreement between subjects and rulers. Well before the turning points of 1776 — before the Declaration of Independence or Thomas Paine’s boast that “We have it in our power to begin the world over again” — they cast themselves in a drama for the ages.
The so-called Suffolk Resolves of 1774, drafted by civic leaders of Suffolk County, Massachusetts, prayed for a life “unfettered by power, unclogged with shackles,” a fight that would determine the “fate of this new world, and of unborn millions.”
The revolution was an ongoing story of surprise and improvization. Military historian Rick Atkinson, whose book “The Fate of the Day” is the second of a planned trilogy on the war, called Lexington and Concord “a clear win for the home team,” if only because the British hadn’t expected such impassioned resistance from the colony’s militia.
The British, ever underestimating those whom King George regarded as a “deluded and unhappy multitude,” would be knocked back again when the rebels promptly framed and transmitted a narrative blaming the royal forces.
“Once shots were fired in Lexington, Samuel Adams and Joseph Warren did all in their power to collect statements from witnesses and to circulate them quickly; it was essential that the colonies, and the world, understand who had fired first,” Schiff said. “Adams was convinced that the Lexington skirmish would be ‘famed in the history of this country.’ He knocked himself out to make clear who the aggressors had been.”
A country still in progress
Neither side imagined a war lasting eight years, or had confidence in what kind of country would be born out of it. The founders united in their quest for self-government but differed how to actually govern, and whether self-government could even last.
Americans have never stopped debating the balance of powers, the rules of enfranchisement or how widely to apply the exhortation, “All men are created equal.”
That debate was very much on display Saturday — though mostly on the fringes and with anti-Trump protesters far outnumbered by flag-waving tourists, locals and history buffs. Many protesters carried signs inspired by the American Revolution including, “Resist Like Its 1775,” and one even brought a puppet featuring an orange-faced Trump.
“It’s a very appropriate place and date to make it clear that, as Americans, we want to take a stand against what we think is an encroaching autocracy,” Glenn Stark, a retired physics professor who was holding a “No Kings” sign and watching the ceremony at the North Bridge.
Massachusetts’ Democratic governor, Maura Healey, who spoke at the North Bridge ceremony, also used the event to remind the cheering crowd that many of the ideals fought for during the Revolutionary War are again at risk.
“We see things that would be familiar to our Revolutionary predecessors — the silencing of critics, the disappearing people from our streets, demands for unquestioned fealty,” she said. “Due process is a foundational right. if it can be discarded for one, it can be lost for all.”
