SEOUL, South Korea (AP) — North Korean leader Kim Jong Un supervised more missile tests from his prized new warship over the weekend, state media said Tuesday, as he pledged to boost the navy’s operational capabilities with his growing collection of nuclear-capable weapons.
North Korea’s official newspaper Rodong Sinmun said Kim on Sunday observed the launches of two strategic cruise missiles and three anti-ship missiles from his 5,000-ton-class destroyer, the Choe Hyon, first unveiled in April 2025. The cruise missiles flew for more than two hours and the anti-ship missiles for more than 30 minutes along pre-set trajectories over the country’s western seas before accurately striking their targets, the newspaper said.
The Korean Central News Agency, another state outlet, published photos of Kim and other senior officials watching from a pier as a projectile trailed gray smoke while arcing away from the warship.
Kim had also supervised two rounds of missile tests from the Choe Hyon last month while vowing to accelerate the nuclear armament of his navy. After Sunday’s tests, he said his government remained focused on the “limitless expansion” of its nuclear forces and issued unspecified new tasks to sharpen the country’s nuclear attack and rapid-response capabilities. He also reviewed plans for the weapons systems for his third and fourth destroyers currently being built, Rodong Sinmun said.
Kim has hailed the development of the Choe Hyon as a major step toward expanding the operational reach and preemptive strike capabilities of his military. State media say the warship is designed to carry a range of systems, including anti-air and anti-ship weapons as well as nuclear-capable ballistic and cruise missiles. South Korean officials and experts say the vessel was likely built with Russian assistance amid deepening military ties, but some experts question whether it’s ready for active service.
North Korea unveiled a second destroyer of the same class in May last year, but it was damaged during a botched launch at the northern port of Chongjin, prompting a furious response from Kim. The country later said the ship, named Kang Kon, was relaunched in June after repairs, but outside experts have questioned whether it’s fully operational.
State media say a third destroyer under construction at the Nampo shipyard on the country’s western coast is expected to be completed by the ruling Workers’ Party’s founding anniversary in October.
The latest launches from the Choe Hyon add to a recent run of weapons tests as North Korea pushes to expand its nuclear-capable forces targeting rival South Korea amid worsening ties and a prolonged freeze in diplomacy.
North Korea conducted a series of tests last week that state media said involved various new weapons systems, including ballistic missiles armed with cluster-bomb warheads, while its senior officials issued crude statements ridiculing South Korean hopes for warmer relations.
Kim has suspended meaningful dialogue with Washington and Seoul since the collapse of his diplomacy with U.S. President Donald Trump in 2019. He has since adopted a hard-line stance toward South Korea, now defining it as his “most hostile” adversary, and rejected U.S. offers to resume talks as Trump entered his second term, urging Washington to drop its demand for denuclearization as a precondition.
Russia has been a top foreign policy priority for Kim in recent years, with North Korea sending thousands of troops and large weapons shipments to support Moscow’s invasion of Ukraine. He has also deepened ties with China, the North’s traditional ally and economic lifeline, and voiced support for Beijing’s push for a “multipolar world” during a meeting last week with Chinese Foreign Minister Wang Yi.

SAN DIEGO (AP) — The smell of rotten eggs permeates Steve Egger's Southern California home, especially at night as the nearby Tijuana River foams up with sewage from Mexico before emptying into the Pacific Ocean.
Egger, 72, says he and his wife have frequent headaches and wake up congested and coughing up phlegm. Their home is outfitted with a hospital-grade filtration system that cycles the air every 15 minutes.
Despite those measures, “most nights we breathe in a horrible stench,” he said. “It’s awful.”
Since 2018, more than 100 billion gallons (378 billion liters) of raw sewage laden with industrial chemicals and trash have poured into the Tijuana River, according to the International Boundary and Water Commission. The river traverses land where three generations of the Egger family once raised dairy cows. The United States and Mexico signed an agreement last year to clean up the longstanding problem by upgrading wastewater plants to keep up with Tijuana’s population growth and industrial waste from factories, many owned by U.S. companies.
In the meantime, tens of thousands of people are being exposed to the sewage. Environmental Protection Agency Administrator Lee Zeldin said during a February visit to San Diego that it will take about two years to resolve one of the nation’s worst and longest-running environmental crises, which affects a largely poor, Latino population.
Raw sewage doesn’t just smell bad. It emits hydrogen sulfide, a toxic gas that can erode neurons in the nose and trigger asthma attacks. It can cause headaches, nausea, delirium, tremors, cough, shortness of breath, skin and eye irritation and even death, according to the Centers for Disease Control and Prevention. Its long-term health problems are only starting to be understood.
There is no federal safety standard for hydrogen sulfide except for workers at sites where the risk is extreme, such as wastewater treatment plants or manure pits. A few states set standards decades ago, but those are outdated. A California proposal would require the state's 56-year-old standard reflect the health risks of the gas. In Texas, lawmakers are also considering updating its law.
“I think when you look back when the standard was first established and then it was reviewed, it was all about nuisance — basically it was all about odor,” said the California bill’s author, Democratic Sen. Steve Padilla, who represents the Tijuana River Valley. “I don’t think we had the understanding scientifically of what the health impacts were here, and now we do.”
Even if the bill passes, the new standard would likely not be developed until 2030.
A “Stop the Stink” sign is on Egger’s fence, part of a campaign that Citizens for Coastal Conservancy launched to demand officials clean up the cross-border sewage.
The 120-mile (195 km)-long river starts in the Mexican city of Tijuana, crosses into California and empties into the ocean. San Diego County beaches nearby have closed for years, and Navy SEALs who train in the water have fallen ill.
Just since January, the Tijuana River has carried 10 billion gallons (38 billion liters) of mostly raw sewage and industrial waste across the U.S. border, according to International Water and Boundary Commission data. By comparison, a massive pipe that ruptured in January sent 244 million gallons (924 million liters) of untreated sewage into the Potomac River, affecting affluent, largely white communities. That spill prompted federal intervention within weeks.
In 2024, a sampling by San Diego County and the CDC representing the roughly 40,000 households close to the Tijuana River found 71% could smell sewage inside their homes and 69% had a member get sick from being exposed.
Even at low levels, “you’re going to feel like it’s in your sinuses. You can’t get rid of the smell. It’s going to be a constant irritation,” said Ryan Sinclair, an associate professor of environmental microbiology at Loma Linda University School of Public Health.
The EPA said it is working with local and state officials to find ways to mitigate the smell.
San Diego County this year distributed over 10,000 air filters to homes. But the air remains a threat. The river’s foam can now be seen from space.
In September 2024, Kimberly Prather, a chemistry professor at the University of California, San Diego, and a team of researchers installed air monitors in the neighborhood where Egger lives.
What they found stunned them: The hydrogen sulfide concentrations were 4,500 times higher than typical urban levels and 150 times higher than California’s air standards when river flows peaked at night.
Many residents, like Egger, felt vindicated.
“They’d been being more or less gaslit and told, ‘There’s gas. It’s a nuisance. It smells, but it’s not bad,’” Prather said.
She said her researchers have since detected thousands of other gases coming from the river that don’t smell, “and many of them are more toxic.”
Egger said doctors have told him to move, though they have not given him a written diagnosis as suffering from hydrogen sulfide exposure.
But his family's roots run deep. His wife grew up in Tijuana. His brother and his late brother’s family live in the neighboring houses on what was Egger Dairy. Nearby are the dilapidated milk barn and rusting farm equipment.
“This is where I've lived all my life, with my family, my parents, my grandparents,” he said. “This is home.”
When Egger was a boy, he swam in the river that ran only during the rainy season. Now mostly filled with sewage and industrial waste, it goes year-round. He says the river should be restored to its historical route, which is closer to the border and farther from most residences and schools. He believes then it would not pond, creating hot spots of hydrogen sulfide gas.
Less than half a mile from Egger’s home, the smell is overwhelming where the river shoots out of pipes after being forced briefly underground near Saturn Boulevard.
Scientists call it “the Saturn hot spot.” The stench permeates passing cars with the windows up, lingering inside for days.
Dr. Matthew Dickson and his wife, Dr. Kimberly Dickson, run a clinic about a mile from the hot spot. Many of their patients suffer from migraines, nausea, wheezing, eye infections and brain fog. Those with asthma say they use their inhalers more when the air reeks.
“They'd say, ‘You know, I feel better when it doesn’t smell outside,’” Dr. Kimberly Dickson said.
In August 2023, a tropical storm caused the river to overflow onto the streets. Within days, the doctors' caseloads tripled.
Electronic health records confirmed what the doctors suspected. When the river flows have jumped, the number of patients they have treated for respiratory problems has increased by 130%, they said.
“Every day that this isn't fixed,” Dr. Matthew Dickson said, “more people are getting sick.”
