Your World Tonight - Iran ceasefire collapses, cancer blood tests, the children of Venezuela, and more

Episode Date: July 8, 2026

U.S. President Donald Trump says the ceasefire between Iran and the U.S. is over. Both countries are trading fire again, in the worst clashes since the two countries signed an agreement to stop fighting last month.And: For cancer survivors, the lingering fear of recurrence never truly fades. A new technology is helping find the tiniest traces of cancer using basic blood work.Also: Weeks after tens of thousands of lives were shattered by the earthquakes that rocked Venezuela, the country’s children face a fragile new reality. CBC is in Venezuela.Plus: Researchers get a look at Shackleton’s last ship — the Quest, more details on charter boat tragedy in B.C., the heat is back in Western Europe, and more.

With the help of Google AI, crop mind is giving farmers early and accurate insights on crop health, helping them protect their harvests and increase yields. Innovation is Canada's story. Let's tell it together. Find out more at g.co slash Canadian innovation. This is a CBC podcast. They're scum. That's the way they act.

And that's the way they've done it for 47 years. U.S. President Donald Trump berates the leaders of Iran and declares the ceasefire over. Both sides accusing the other of violating the truce as the U.S. resume strikes on Iran for a second night. But speaking on the NATO summit in Turkey, Trump is painting a much rosier picture of relations with most member countries. They love us. They love each other. That was tremendous unification. Trump hails the gathering as a success while calling Spain a terrible partner that should have trade with the U.S. cut off. This is your world tonight. I'm Martina Fitzgerald.

It's Wednesday, July 8th coming up on 6 p.m. Eastern. Also on the podcast. What we're trying to do is to see whether these sensitive tests can detect circulating tumor DNA. A breakthrough cancer test that requires just blood work that could help detect cancer sooner or make sure it's gone after treatment. The experimental procedure is generating excitement among researchers and concern about the potential downsides. The U.S. military has launched another round of strike. on Iran tonight, making good on Donald Trump's threats to hit back even harder after Iran struck

three ships in the Strait of Hormuz and both sides traded fire last night. These are the worst clashes between the U.S. and Iran since the two countries signed a 60-day suspension of hostilities last month. Paul Hunter has the latest. Well before, word of the latest U.S. strikes on Iran, images on Iranian TV of what was said to be the latest Iranian missile launches overnight aimed at U.S. target. Military sites in Bahrain and Kuwait and as well. Oh, apparent cell phone video that appears to show missile strikes on Iran at one of its southern

ports off the Strait of Hormuz, the U.S. having also targeted Iran overnight, after Iran again attacked oil tankers in the state. straight, the back and forth, underlining the on again, off again fighting between Iran and the U.S. is on. Again, it seems. They're scum. They're sick people. They're led by sick people. And they're vicious, violent people. At the NATO conference in Turkey, U.S. President Donald Trump suggesting the interim agreement to end the war with Iran might well be over. As far as I'm concerned, it's just a waste of time dealing with them. They're liars.

Trump also previewing that from the U.S. military there'd indeed be more to come imminently. Somebody else before, do you think you'll hit him tonight? I said, we might, yeah, we might. I think anything that happens is going to be over very quickly. Though he also underlined, he does not think this latest battling will reignite a full-fledged war. No, I don't think it's going to start again. I think it's going to go very quickly. They hit a couple of ships, and so we hit them much harder. They hit, we hit 10 times harder. You know, we hit much harder than they do.

So what to make of it all? It is quite by definition not a cease fire when the two sides continue to fire at one another. Ned Price, spokesman for the U.S. State Department under Joe Biden says he expects the stop-start, stop-start fighting will continue for weeks, maybe months. Where escalation and exchange of fire gives way to an uneasy truce only to be violated by one side or another and to find ourselves right back here. All of this on a day Trump called the Iranians cuckoo, as oil prices again surged, and questions on whether a permanent ceasefire is even reachable grew, as Trump himself put it.

I'm not sure I want to make a deal with him. We can play games, but I'm not sure I want to make a deal. Let's just finish the job. Says Iran, the earlier U.S. strikes overnight were a, quote, blatant act of aggression. Iranian media reporting, should things escalate, Iran would close the Strait of Hormuz. Again, Paul Hunter, CBC News, Washington. Despite days of public rebuke from Donald Trump, NATO leaders wrapped up their two-day meeting in Ankara with a strategic show of unity, committing to mutual defense, but not committing to when they might meet again.

As Murray Brewster reports, some analysts say that omission speaks volumes. The president's here. He's in a good move. Prime Minister Mark Carney must have a flexible definition of good mood when it comes to U.S. President Donald Trump. Spain is a terrible partner in NATO. They don't participate. They don't pay. I don't want anything to do with Spain. Cut off all trade with Spain. Trump was clearly in a mood, unleashing a litany of grievances.

Some old, some new, such as the extended tirade against Spain, saying at one point the only reason he came to NATO was his friendship with the Turkish president. We've been treated unfairly. We paid disproportionately. And while there's been no public blowout, there was muted exasperation as leaders adjourned, expressing appreciation to their Turkish hosts, saying they'll meet again, but not saying when. A change from previous years and an ambiguous end that leaves the next host country, Albania, somewhat in limbo. It's a result defense analysts saw coming. NATO normally does not have summits every year. Max Bergman of the Center of Strategic and International Studies in Washington says up until Russia's 2014 invasion of Crimea, NATO leaders

met less frequently, and there seems to be an appetite to return to that while Trump remains in office. It wouldn't not surprise me if this is, frankly, the last NATO summit of the Trump administration, of Trump's presidency. Frankly, I think that makes a lot of sense, and I think a lot of European leaders would jump at that. There were published reports today, the idea of postponing Albania was actively discussed. Prior to the summit, the U.S. soed, military uncertainty saying it wasn't going to commit as many forces towards NATO in the event of war than it has in the past. It was also reviewing what troops are in the field and the amount of money it contributes to keeping the alliance running. NATO is structured around the United States and has been

for the last 77 years and that's how we have wanted it. And so if you pull the U.S. back, how do these countries work together on defense? It is really important. political question, one that Europeans are currently reckoning with. The question of what might mollify Trump, or even if it's worth trying anymore, is also a preoccupation. Prime Minister Mark Carney says the debate over Trump's biggest grievance, spending, has largely been settled. As part of the point I made to President Trump when we spoke a few days ago, is that it's not just he's winning the argument, he's won the argument.

Carney left the summit almost immediately at its conclusion, heading to Saudi Arabia for business and investment meetings before returning home Friday. Murray Brewster, CBC News, Jetta, Saudi Arabia. Coming right up, the latest on the sinking of a fishing charter boat off the BC coast. Plus, southwestern Europe sizzles under yet another heat wave. We'll take you to France where temperatures are expected to rise for the rest of the week. And later, we'll have this story. This doesn't work out. That's it.

There's one chance to try and capture the first images of Quest, a ship once used by explorer Ernest Shackleton. I'm Peter Cowan on board the research ship Atlantis. I'll tell you why the Royal Canadian Geographical Society is mounting this expedition and what they found. It's a wrecked wreck. That story later on your world tonight. One of four people rescued after a fishing charter boat sank off BC's lower mainland has died in hospital.

Six other people are presumed round. The sinking was 11 days. ago. Searchers using an underwater drone located the vessel on Monday, but so far no bodies have been found. Our Tanya Fletcher is tracking this story for us in Vancouver. Tanya, we're learning more about who was on that boat. What can you tell us about the victims? Yes, and Martina, we know there were 10 people on board at the time. Four survivors were pulled from the water when that boat began to sink. Most of them were treated and released from the hospital since then, but one has now died. We know it was a 28-year-old Chinese woman living in Seattle. The survivors are a 33-year-old woman from Toronto, a 26-year-old man

from Richmond, B.C., and a 33-year-old man from Redmond, Washington. The six others on board, including the captain, remain missing. They are presumed drown. And they're all relatively young as well, between the ages of 22 and 33, and they're also from Toronto, B.C., and Washington state. Also new, RCMP have now identified the boat. It's named the Top Ocean, a 2017 Kingfisher model, and it's operated by a company called Top Vancouver Fishing Charter. But still, there are so many unanswered questions. Can you take us through the logistical challenges of this investigation? The sunken boat is 153 meters deep. That's over 500 feet. RCMP dive teams did locate the wreckage on Monday more than a week after it sank, and they did

that using underwater drones. They say it's too deep for divers to go down. down that far. But the drone did get a good look around the seabed, around the boat. It didn't spot any bodies, and RSEMP say it's entirely possible. They're all still inside the wreckage. We spoke today with a local underwater dive company based in North Vancouver. It's called Newt Co Research. And President Jeff Heaton says this recovery is especially tricky because it's so deep. It's very, very dirty. And when you couple that poor visibility with the current, it becomes is really hard to do when he work. He says RCMP actually contacted his company about this search,

and they told him the boat is currently upright at the bottom of the ocean floor. Now, still a lot we don't know. We asked if the captain was licensed for a charter like this. And our CMP spokesperson said they didn't know. Was the boat properly licensed? Were the people on board wearing life jackets as they're required to? Police didn't have answers for that either, though we can tell you the people on a sailboat.

some rescuers who were first on scene and helped those three survivors to safety out of the water had said none of them had flotation devices from what they could see at the time. We've also reached out to the charter company that owns the boat. So far they've refused to comment. We know the Transportation Safety Board is investigating. So far are questions to them about, you know, regulations, enforcement accountability. They've referred us to Transport Canada, which has not yet given us a response. Martina. The CBC's Tanya Fletcher in Vancouver. Thank you, Tanya. You bet.

Cancer patients often face a battery of treatments and tests in the hope of becoming cancer-free. But there is often a lingering thought for survivors. Is the cancer coming back? Now a new technology is helping find the tiniest traces of cancer left in someone's body all through basic blood work. As health reporter Lauren Pelly tells us, Canadian scientists are at the forefront of a major new research project to see how well it works. I was getting ready to go for a radiation treatment. Paul Lonergan points to a photo of himself in a hospital bed. The Toronto resident battled tongue cancer through months of chemo and radiation. After his treatments finished, his oncologist told him the tumor was gone.

But you still have fragments of cancer in your blood. Lonnergan got those astonishing results through a clinical trial studying liquid biopsies. This emerging technology looks for tiny, fragments of tumor DNA in someone's bloodstream before it ever shows up on a traditional exam or scan. Now a team of Canadian scientists wants to test it out on thousands of cancer survivors. And what we're trying to do is to see whether these sensitive tests can detect circulating tumor DNA. Dr. Lillian Sue is leading this massive research project. She's a senior scientist with the Princess Margaret Cancer Center, part of the University Health Network in Toronto.

And the hope obviously is when you detect it so early, we can do something about it earlier. In cases where researchers spot signs of someone's cancer coming back, the team will link them with other trials offering next-generation treatments, such as new medications or experimental therapies. For other patients, simple blood tests could give them the chance to watch and wait, potentially sparing them from enduring more treatment and side effects. Sue hopes to follow 7,000 cancer surveillance. survivors over the next five years.

And if we can provide that kind of data to provide the evidence, then this test will eventually become a routine test, a standard test, and that can benefit a large number of patients. Liquid biopsies aren't yet available to the vast majority of cancer patients outside of clinical trials. But a growing body of research does show links between catching tumor fragments early and patients experiencing longer survival times. This is certainly an exciting technology,

but it's early days. Dr. Christopher Booth is a medical oncologist and researcher with Queen's University. He said further studies on these tests will be crucial to figure out the best way to use them for cancer patients who've already endured grueling medical treatments. And then you add on top of that the possibility of a false negative or a false positive test, and there can be significant emotional burdens. In Lonergan's case, once he found out there were traces of tumor DNA still in his bloodstream, He just wanted it gone. I got to be a father.

I want to keep playing hockey, and I've got some work to finish. And that's what's going through my head. Lonrigan ended up having experimental immunotherapy. Now he's considered cancer-free. Lauren Pelley, CBC News, Toronto. Meta will establish its first Canadian AI data center in Alberta. The tech company behind Facebook, Instagram, and WhatsApp says

it will invest $13 billion to build the facility in Sturgeon County. Premier Danielle Smith says the project will create thousands of construction jobs and bring millions of dollars into Alberta. She also said the province and META have listened to the concerns of people and other places where data centers have been proposed. We've developed an approval process to address each of the issues that we've heard. So this is being cited in an industrial area that's been well established for four decades. There were supposed to be 12 refineries on that site.

And so people in that area were expecting that there was going to be this kind of heavy industrial use. They obviously responded to the concerns about water use because they're using the closed-loop system and air cooling. And they also worked with us to make sure that there wasn't going to be a peak in power prices by building their own power. Betta says it has partners to build new power generation and grid infrastructure and will spend $60 million to improve local infrastructure, such as roads and water systems. Air Canada has a new CEO, who has at least one skill, his predecessor in the job,

never quite mastered. Air Canada plays a role unique as the transporter national of a verguer mondial. Air Canada's new CEO is from the Netherlands, but communicates in both of Canada's official languages. Anko Verde Verf is leaving his job at Scandinavian. Airlines to succeed Michael Russo at Air Canada. Russo announced his retirement earlier this year after a backlash from French-speaking Canadians.

Russo had posted an English-only condolence message following a deadly crash at New York's LaGuardia Airport. The crash killed two pilots, including one from Quebec. Parts of Europe have been baking under heat wave after heat wave this summer. French officials say over eight days in late June when it was sweltering, there were two thousand more deaths than usual, and they say that number could actually be much higher. Even as experts are still trying to assess the effect of last month's heat wave, there's another one underway. Breyer Stewart has that story from Paris. In the midday afternoon heat, 89-year-old Bani Krepe sits on a bench underneath an awning

at a bus stop, resting before she wheels her shopping trolley to a local market. She says during last month's record-breaking. heat wave, she had problems breathing and felt sick. This is the third heat wave to hit France this year. At the end of June, as temperatures went above 40 in some parts of the country, the number of deaths reported surged by nearly 30%. We had at least 15 more people who died in the streets of Paris homeless people, who died and it was linked to the heat wave. Paul Alonzi is a social worker with the non-profit group Medesan Dumont. A few times a week, he and his team visit a 500-meter stretch in eastern Paris,

where around 1,000 people, many of them asylum seekers, are living in tents set up under the metro line. When the temperature goes over 40, the feeling that you have is 45, 50 degrees, because this is a jungle of concrete. 47-year-old Mahmouhavir points to one of the tents he's been sleeping in for over two years. This is nylon. It's very hot. He says during the heat wave, he's been escaping to the river to cool off.

Swimming spots have been set up across the city, including one near the base of the Eiffel Tower. We really see a big difference in the temperature than when I was a child, for example. Violette Dumolins enjoys swimming in the seine and tries to avoid spending any time in her top floor apartment. Like three quarters of all of the homes in France, it doesn't have air conditioning. Especially in Paris, when you have all the buildings,

not very vegetation, so it depends on where you live, it's a really big problem. Climate scientists say Europe is the fastest warming continent. In recent weeks, temperature records have been smashed across several countries, including France, Spain and Germany. Samantha Burgess is the deputy director of the EU Earth Observation Agency Copernicus. More of society will be impacted. Schools will continue to close.

Roads will melt until we adapt that infrastructure to cope with our new climatological normal. And for France, the forecast is projecting temperatures in the mid-to-high-30s for at least another week. Breyer-Stewart, CBC News, Paris. Tens of thousands of lives were shattered by the earthquakes that rocked Venezuela two weeks ago today. Among those who have suffered most are children. who've lost homes, family, and now face completely altered lives. Other children remain missing, their parents desperate to find them. Jorge Barrera has that story from Venezuela.

I didn't like living through this experience, says 11-year-old Nazareth. I almost lost my mom because things were shaking so much. She is now living in a donated tent with other displaced families in a parking lot, riven by deep cracks, near the Caribbean shores of Katya Lamar, La Guaida. I want to sleep in my bed, she says. I don't want to sleep on the floor, on a mattress. I don't want to live this experience anymore. At their request of NGO save the children,

CBC News agreed not to use the real names of any children interviewed in this story. They are among over 600,000 children impacted by the devastating twin earthquakes that struck Venezuela. We speak to children who, they've lost family members, they've lost friends. Aisha Mahiris with Save the Children, which provides programming at this camp

set up by families who lost their homes in the area. I always carry a sadness in my heart, says 9-year-old Leo, thinking that it could happen again. It's scary. You think you are going to die and not be able to see your mother anywhere.

year. I'm not going back to my school, says Emma. We are moving. I have to say goodbye to all my friends. She says her mom doesn't want to stay here because it could happen again. Not far from here. In another beachfront, La Guaida town called Playa Grande, two mothers search for their missing children.

Carmona Marquez Basabeth says several people told her they saw her 10-year-old son, Paul Jr., running after the quake. He was playing with Rosanna del Carmen Carvasa's 10-year-old son, Emmanuel Abraham. They both vanished together. Their mothers continue to search, sleeping on the sidewalk in tents, across from their destroyed homes. We have faith that our children are okay, she said. Faith is all they have left. Jorge Barrera, CBC News, Playa Grande, La Guaida, Venezuela. An expedition off Labrador is sending back the first images

of the final ship used by explorer Ernest Shackleton. The quest was one of the last ships from the heroic age of exploration of the Earth's most extreme environments. It sank in 1962. It was found two years ago. Experts are now getting a first-hand look at what's left. The CBC's Peter Cowell. is on board.

If it's free, it's copper. It was well past midnight when the first images flashed up on the computer screens in the laboratory on board the research ship Atlantis. The old timbers are covered with coral and sea life, captured by a remotely operated vehicle. David Kearns is the co-chief scientist on this mission and a professional shipwreck hunter. Even without seeing a name, he knows this is quest. It's the right wooden ship.

It's the right sides. It's got the right accommodations, and it's got white paints. That's the question. Ernest Shackleton bought this ship in 1921. At first, he wanted to explore Canada's Arctic. But when the government wouldn't back his mission, he headed south to Antarctica. On board quest, he had a heart attack and died. Decades later, it was a sealing ship when it sank off the coast of Labrador.

The Royal Canadian Geographical Society located the ship two years ago. Now it's getting the first images. No one on the expedition expected to see the wreck covered in fishing nets. From a biological point of view, it's very interesting. Archaeological is still interesting, but from the point of view of coming back with a pretty picture of a shipwreck, that's debatable from what we've seen so far. It's a wrecked wreck.

Antoine Normandandale led the research on Quest and helped pinpoint the location. He says the nets have likely damaged the shipwreck. It certainly is disappointing, and it does bring up the issue of the preservation of cultural assets and natural assets and the impact go for industrial fishing on that one. The federal government closed the area to fishing in 2002.

The nets are likely decades old. L.C. Bridge, you have permission to launch stuff. Roger, permission to launch. This expedition is the most expensive ever for the geographical society. It's costing them millions. It's partnering with the Woods Hole Oceanographic Institution, using its submersible Alvin to take people down to the wreck. John Geiger is head of the society and was on the first dive.

We actually lay eyes on a ship that Jacqueline. sailed on is, I mean, it's incredible. It's absolutely incredible. So, you know, for me, it's personally moving. Geyer joined the expedition from Norway. He runs the Fromm Museum, dedicated to polar exploration. On this trip, they're mapping the wreck in three dimensions to create a digital model that anyone can explore without mounting an expedition. More we tell these stories, and especially now with new digital technology, these stories will reach a new audience, and maybe get them excited and learn more about our past.

Their next quest is the shipwreck Teranova. It's the ship Robert Falcon Scott used to reach the South Pole. It sits just off Greenland. Peter Cowan, CBC News, on board the research ship Atlantis in the Labrador Sea. And finally tonight. A song of celebration in the indigenous language of Klingit at the graduation ceremony at the Yukon Native Language Center in Whitehorse. Some of the people you're hearing are able to sing those words

thanks to months and years of hard work, studying with elders, passing their traditional languages from one generation to the next. It means so much to me. I actually can't believe I'm here. Graduate Patty Wallingham says she took the program not just to further language preservation,

but also to honor her ancestors. She says it was tough, but worth it. It was so hard and definitely was challenging to keep going at times, but I'm so glad we did it, and I could not have done it with them. the rest of my cohort. They are amazing. They're like sisters to me now. The Indigenous Languages Program is run in partnership with Simon Fraser University.

Since 1993, it's offered courses on more than 20 indigenous languages across British Columbia and Yukon. Grand Chief Mathia Alitini of the Council of Yukon First Nations was at the White Horse Ceremony. She says learning language is at the core of cultural revitalization. When you know your language, you start to identify stronger, with who you are as a southern Chishonni person, as a Klinget person, as a northern Chishonni or Han person. And it also is tied to place. So it reconnects you to land.

And I think that is immeasurable. The 11 Yukon graduates received certificates and diplomas. Many say they plan to continue learning and spreading language knowledge back home in their own communities. Thanks for being with us. This has been your world tonight. for Wednesday, July 8th. I'm Martina Fitzgerald.
