Tonight on PBS News Weekend, Ukraine comes under pressure as US and Ukrainian officials meet in Switzerland to discuss plans to end the war with Russia.

Then, as the Trump administration pushes for more arrests of migrants, we explore how federal agents are escalating their tactics.

And deep in Brazil's Amazon rainforest, scientists have built a time capsule to predict the future of climate change.

From these towers, we will release CO2 into the treetops and try to create the atmosphere of the future there.

Then we can study all the ecological processes that will be altered with more carbon in the system.

Good evening.

I'm Ali Rogin.

John Yang is away.

A full court press in Geneva tonight as US officials put the heat on Ukraine to accept a peace deal.

Who authored the plan became a point of contention while President Trump said Ukrainian leadership had expressed zero gratitude for American efforts.

Nick Schifrin has more on the diplomatic efforts spanning oceans.

Today in Geneva, a meeting that could help determine Ukraine's fate and what Secretary of State and National Security Adviser Marco Rubio described as substantial progress.

It is probably the most productive day we have had on this issue maybe in the entirety of our engagement but certainly in a very long time.

The Ukrainian delegation led by presidential chief of staff Andre Yermach used the same language.

We have very good progress and we are moving forward to the just and lasting peace.

The US's 28point plan presented last week would cap the size of Ukraine's military and block NATO from sending any troops to Ukraine.

Ukraine would also have to give up the portion of the Donetsk region it still controls, handing Russia control over the entire Donbass, which the US would then recognize with occupied Crimea and the occupied portions of Zaparisia and Hersan as de facto Russian.

And a separate US document gives Ukraine a security guarantee that a quote significant, deliberate, and sustained armed attack by the Russian Federation may lead to an armed response.

But today, Ukraine presented its own text coordinated with the United Kingdom, Germany, and France, known as the E3.

And in the E3 draft, provided to Ukraine and obtained by PBS News, Ukraine would not have to give up land, but would start negotiations based on the front lines.

The US would not give Russia deacto recognition of occupied Ukrainian territory.

The E3 draft eliminates a clause that would have given Russia amnesty for war crimes and NATO would not block Ukraine's future membership, but would acknowledge their membership is not fully supported.

Today, Rubio said the disagreements that remained could be solved.

I can tell you that the items that remain open are not insurmountable.

We just need more time than what we have today.

And Rubio suggested more time might also mean Ukraine does not face a Thursday deadline.

By which time a European official told PBS News the US initially threatened to cut off weapons and intelligence sharing.

Whether it's Thursday, whether it's Friday, whether it's Wednesday, whether it's Monday of the following week, we want it to be soon because people are going to between today and the time we deal with this, more people are going to die.

More destruction is going to happen.

And so it was today.

In southern Ukraine, Russian drones injured more than 12 and damaged this apartment block.

The price that Ukrainians pay every day is measured in what will be fixed, but also the irreplaceable.

A father in western Ukraine holds the body of his one and a half-year-old son and says goodbye one last time after his wife and two children were killed in a Russian strike.

Nick Schifrin joins me now.

Nick, do we know anything about the substance of these exchanges in Geneva today?

So Ally, the UK, Germany, France, the E3 did give those proposals to Ukraine for the things that they wanted to see edit.

We highlighted some of those in the story.

There are other proposed changes, including capping uh including raising the cap on Ukraine's military and watering down the restrictions on Ukraine's NATO ambitions and NATO troops in Ukraine.

Uh, we don't know exactly the items that your mock emphasized in those in the meeting with Rubio and the US officials, but Zalinsky said tonight there are quote signals that President Trump's team is hearing us.

And yesterday, Trump did say that the 28-point plan was quote not his final proposal, suggesting the US is open to edits.

Uh but as you said at the top, the president of the United States also criticized Ukraine today for not showing or showing zero gratitude and he he put Ukraine's leadership in quotation marks.

Uh and a US and European official tell me this uh that Dan Driscoll uh after he met with Ukrainian President Vadimir Zalinski in Kev.

You see them there.

He told European diplomats that quote the honest US military assessment is that Ukraine is in a very bad position and now is the best time for peace.

Ali for Driscoll to say that in Kev really reveals how skeptical the US is of any argument that giving Ukraine more weapons would produce any results.

Now let's talk about last night you were at the Halifax security international security forum with a congressional delegation.

Uh and those members changed the narrative pretty dramatically last night.

At least for a few hours.

Yeah, for a few hours.

Uh, so this was a bipartisan group of senators led by New Hampshire Democrat Jean Shaheen, but alongside uh, North Dakota Republican, sorry, South Dakota Republican Mike Rounds and Maine independent Angus King.

Uh, and they announced to the press that Rubio told them that the 28-point plan was not a US document.

It was actually a Russian document.

Let's listen to rounds and then King.

What I can share with you is what we've received today from the secretary and what he told us was that this was not the the the American proposal.

This was a proposal which was received by someone who has re identified and they believe to be representing uh Russia.

The leaked uh 28point plan uh which according to Secretary Rubio is not the administration's position.

It is uh essentially the the the wish list of of of the Russians.

Browns even said that Rubio gave him permission to make that announcement.

But after I posted Rounds's statement on X, Rubio's spokesperson replied to me in a message saying quote that this is an outright lie.

Uh after that, rounds posted a new statement on X saying, quote, "I appreciate Secretary Rubio briefing us earlier today on their efforts to bring about peace by relying on input from both Russia and Ukraine to arrive at a final deal."

So he didn't repeat what he said the other day, nor did he disavow it.

And King said the same, releasing this statement.

It is troubling the plan appears to have been developed after extensive consultation with the Russians and little if any input from Ukraine or European allies.

does not repeat that in Rubio's name alley, nor does he disavow the statement.

The bottom line is that Rubio says the 28point plan is a US plan, not a Russian plan.

And the question of who's telling the truth here, frankly, I don't know and we may not know because the bottom line is these are senators, former governors.

They say they heard what they said.

Did they hear what they wanted to hear?

We just don't know.

Nick Schifrin, excellent reporting.

Thank you so much.

Thank you.

In tonight's other headlines, Israel carried out an air strike in Lebanon's capital city today, nearly one year to the day the country agreed to a ceasefire with Hezbollah.

The strike killed at least five people and wounded dozens of others.

Israel said the target of the strike was a key Hezbollah military leader considered the terror group's chief of staff.

An Israeli government spokesperson declined to say whether officials informed the US ahead of the strike.

The US helped broker that ceasefire deal last November.

Since that time, Israel has alleged Hezbollah is trying to rebuild and rearm.

In northern Nigeria, 50 of the 303 children kidnapped from a Catholic school on Friday have escaped and reunited with their families.

They were taken by armed gunmen from a remote community in one of the worst mass abductions the country has seen.

The search is ongoing for the students and teachers who remain captive.

No group has claimed responsibility.

President Trump has accused Nigeria of failing to curb Christian persecution.

Attacks in the country have both affected Christians and Muslims.

This year's G20 summit ended with little fanfare after the US decided to boycott the global summit.

We shall see each other again next year.

The summit is therefore closed.

Traditionally, there is a handoff of the gavl to next year's host nation, which is the United States.

However, President Trump refused to attend the summit, accusing South Africa's black majority government of persecuting its white minority citizens.

While the lack of US participation overshadowed the event, leaders who attended formally pledged to help poorer nations recover after climate related disasters and agreed to aid in their transition to green energy.

Two East Coast rivals turned out strong defense in the battle for the National Women's Soccer League Championship.

Gotham Football Club of New York took on the Washington Spirit late Saturday in a nailbiter.

The match was scoreless until the 80th minute.

That's when defender Brunia crossed the ball to veteran midfielder Rose Lavell, who put it away past the outstretched arms of the goalkeeper.

It was a sweet victory for Gotham, who secured its second title in three years.

Still to come on PBS News Weekend, a new film tells the story of women who survived a catastrophic fire at an infamous Iranian prison.

And we travel deep into the Amazon rainforest to see how scientists hope to get a glimpse of the future.

From Los Angeles to Chicago and now Charlotte, North Carolina, federal law enforcement agents are arresting immigrants, both legal residents and undocumented, in raids unfolding in the public eye.

Videos circulating online show agents pinning protesters to the ground, smashing the windows of cars, and dragging suspected undocumented immigrants away from their families.

For more on these escalating tactics, we're joined by Michelle Hackman, immigration reporter for the Wall Street Journal.

Thank you so much for joining us.

So, what are these tactics that law enforcement are using now in these immigration uh operations and how do they differ from what they've done in the past?

Yeah.

So, I would say there are two really big differences.

One is that at the start of the Trump administration, the decision they made, you know, in the past when ICE would do an arrest, they were interested in doing numbers and and the easiest way to make an arrest is to catch someone basically as they're coming out of jail.

Well, this administration made a a calculated decision that, you know, they believe that a lot of immigrants are out there in the country.

They call them fugitives.

And so, they're doing a lot more street arrests, which means they're tracking people down where they live, where they're dropping their kids off at school.

And that's leading to a lot of confrontations that we just used to not see before.

And those confrontations are happening not just with the people they're targeting, but certainly the surrounding crowds, passers by who become onlookers.

How is that working out?

Yeah.

So, we've seen these huge deployments of border patrol agents, you know, typic who are typically at the border and not used to dealing with crowds and protesters and suddenly they're deployed in these big cities like Chicago.

I'm sure viewers have seen, you know, and and crowds of protesters don't love this huge law enforcement presence in their communities.

And so, they've been coming out protesting, you know, peacefully protesting.

Um, and there have been a lot of instances where you've seen law enforcement like, you know, basically throw pepper balls at people's heads, use tear gas, and and it's gotten to the point where a judge even ruled at one point like you cannot uh tear gas or throw pepper balls at someone's head unprovoked.

And what sort of training are these officers getting if they've previously only really done service at the border?

What sort of training are they getting before they're deploying to these more densely populated areas?

I don't believe that there's any special training.

You know what one thing that's interesting is that we think of the people doing these arrests as ICE, but actually what this administration has done is they've taken people from all over the government, you know, primarily the border patrol, but also FBI agents, DEA agents who are getting at most a two-week crash course in immigration and are not being sort of given the really detailed training that ICE officers get that involves dealing with, you know, resistance and protest.

protesters and you know you make an arrest people people will try to run away they they don't get all that and you've also covered the disagreements that are happening between ICE Immigration and Customs Enforcement and uh Border Patrol officers who are really following the lead of Homeland Security Secretary Christy Nome who's really uh advocating for these stronger more aggressive measures.

What is that internal uh debate?

How is that playing out?

Yeah.

So, it's really interesting.

It's over tactics, I would say, if I were to boil it down.

So, ICE officers are I mean, almost like trained police and when they when they go to make an arrest, they typically will do some advanced work.

You know, is this person actually in the country illegally?

Where do they live?

What's the best time of day to go get them?

And it's not that those don't ever lead to confrontations.

They often do.

But what we've seen these border patrol agents in these big cities in Los Angeles, Chicago, you know, just this past couple weeks they've been in Charlotte, North Carolina, what they do is they actually use profiling tactics.

I mean, they talk about this.

Is the person speaking Spanish?

Do they look scared?

You know, do they work in a job that is typically held by an immigrant in the country illegally?

And then they'll go and they'll basically check, is this person here legally?

And then do the arrest.

How effective are these new tactics that are being used at achieving the administration's goal of deporting the maximum amount of people they can?

Yeah, it's a really good question and I think people at ICE feel frustrated because when you know when you're using almost like a profiling tactic to make arrests, it's sloppy.

It's scattershot.

You end up taking in a lot of people who maybe are immigrants but have some kind of legal status that's preventing them from being deported.

maybe they're a US citizen, you know, that's why we've heard a lot more cases of US citizens being detained for a few hours before they get released.

Um, and so they are making, you know, a lot of arrests, but a lot of those people tend tend to get released, don't ultimately get deported.

I think on the flip side, though, the thing that this administration really loves about these tactics is that they're really public and they're very scary and it's driving a lot of people to say, you know what, it's not worth it.

I'm too scared.

I don't want to wait for ICE to come arrest me in front of my child.

I think I'm going to make arrangements to leave the country myself.

And so what is the effect on immigrants both documented and undocumented as well as the communities that they live in?

There is I would say pretty widespread terror and not just you know not just the immigrants themselves.

I would say people who are watching these arrests happen there.

We've heard from a lot of bystanders in places like Chicago and Charlotte, you know, be like, you know, I this arrest was made in my front yard.

This is really scary.

You know, I don't know what's happening.

I don't know why someone's attacking my rights like this.

And we've also seen sort of resistance pop up where like, you know, people will walk around neighborhoods and hand out whistles to make sure, you know, if you see border patrol, start whistling so the immigrants nearby know that it's not safe.

They need to go hide.

Michelle Hackman with the Wall Street Journal.

Thank you so much.

Thank you.

Woman, life, freedom.

It's been the rallying cry of Iranians protesting the Islamic Republic since the death of Masa Zena Amini in 2022 following her arrest for improperly wearing her hijab.

Thousands of protesters, including women and children, were arrested in the months following Amini's death.

Many spent time at the notorious Aine prison in Thran.

One night, a fire broke out, threatening the lives of the detained people inside.

Three years later, details of the fire and of the prisoners remain scarce.

But now, one survivor has given her account, and it's the subject of a new short film called That Night.

I recently spoke with the director, Hoda Subani.

Hoda, thank you so much for being here.

This film tells the story of the night of the massive fire at the Evin prison in Thran through the eyes of your friend who's a survivor of that fire, Naan Naji.

Why did you feel strongly about telling NATO's story?

Since I was 19, I had many friends who ended up in prison because of the political activities back in green movement 2009 and then after that many other friends and nea was one of my best friends in Iran who ended up in prison and I wanted to have the conversation with her.

So she doesn't carry this pain by herself and also the fire night had very huge impact on her life and on my life and many others and was a big news headline all over the world.

So I was like this is a very literal story of why prison is a place that the government and regime is using it to oppress more its opponent and it's very clear that they don't want information about the prison to get out.

In fact we see in the film Na being told by guards don't talk about this once she's released.

She's not supposed to say anything.

And now she's the star of this film.

How did she feel?

Was she scared about speaking out about her experience?

I would say no because she's very brave and she like I would say yeah it was like few days after she got released we had the first interview because it was very important to remember the details of what happened that night in their cell in their war.

But when she was inside of Iran, we didn't tell anyone that we are making the film.

And then after a few months, she left Iran to Germany.

And then we started like talking publicly about this film.

This film is mostly an animated film.

Why did you make that choice?

It's a very good question because I think animation is one of the artistic forms that we grew up with and it's the first way we learn to receive stories and learn stories and I feel like all of these news in authoritarian countries like Iran and many others around the world we consume news about violence on a daily basis.

it almost becomes the background routine and I felt like the animation can help us to lift us out of these constant uh news headlines and these headlines are are trying to turn us into numbers and statistics but animation brings back the focus into human story and human experience.

This event, the fire, remains shrouded in so much mystery.

We still don't really know how it started, who was involved.

Why is there still so much that we don't know about the circumstances of the fire?

And do people in Iran talk about this publicly?

It was different for those who were inside of the prison and those who were outside?

We were seeing videos and footage of fire and those who were inside were hearing mostly gunfires and tear gas going into their cells.

We are trying to find out how we can get more information about that night and find out the truth about that night.

But because it's prison and there is like these walls between people so no one can like talk to each other and say what exactly happened and there is not a united POV between everyone.

What do you want people watching the film to take away about the woman life freedom movement and also its strength right now.

First of all, many women in not all of Iran, but many cities, they don't wear mandatory hijab anymore.

But I feel the government is very angry.

The hierarchy and like you know the patriarchal government of Iran is very angry and mad at women, Iranian women and they are trying to put back the pressure on like a legal system on them like marriage law or like civil rights on them.

But I know that my friends and everyone that I know in Iran, they are trying and they are doing that they are finding ways to fight against this system and to ask for their very basic rights.

The film is that night.

Hoda Subhani, thank you so much for joining us.

Thank you so much for having me.

Finally, tonight, hundreds of miles from the UN Conference on Climate Change that wrapped up this weekend in Bell, Brazil, there's a firstofits-kind experiment that could help future policy makers address the issue.

Here's John Yang.

In the Amazon jungle, steel towers peak over the tops of mature trees.

Scientists call it a time machine, giving them a glimpse into the future.

Carlos Alberto Casada is coordinator at Brazil's National Institute of Amazonian Research.

From these towers, we will release CO2 into the treetops and try to create the atmosphere of the future there in that environment.

Then we can study all the ecological processes that will be altered with more carbon in the system.

It's part of a groundbreaking program called Amazon FACE Free Air CO2 Enrichment.

The idea is to pump CO2 into the tree canopies to replicate rising greenhouse gas emissions.

Researchers use cranes to collect data about water use, leaf resistance, and other indications of the treere's health.

They hope these readings will provide an insight into the Amazon's ability to adapt to climate change.

With these sensors, we can get the forest's response every 10 minutes.

For example, if it rains, if it's sunny, if there's a storm, we know how the forest works.

Amazon's rainforest is sometimes called the lungs of the Earth, absorbing billions of tons of carbon dioxide every year and releasing oxygen.

Its health is directly tied to the planets.

It affects rainfall worldwide and the overall balance of the Earth's water system.

Researchers hope the data this experiment yields will help global policy makers better navigate climate change.

How much CO2 can we still admit within a twoderee temperature increase?

We will be able to understand what trajectories the Amazon will take and prepare decades in advance.

Now on the NewsHour Instagram account, a new poll highlights what Americans think the Trump administration should make its priority.

We would love to see your comments in the section on the NewsHour Instagram account.

And that's our program for tonight.

I'm Ally Rogan.

For all of my colleagues, thanks for joining us.

Have a good week.
