Mothers carrying their children smile, give me a thumbs up, and then point to a riverbank 50 metres or so away.
We’re on a walkway bridge between the Mexican city of Matamoros and Brownsville in Texas. The riverbank is of course the United States – so close you feel you can almost touch it.
For these families wide-eyed with excitement, this is the moment they’ve dreamt of. Many have endured months, even years, on the road.
Sometimes travelling thousands of miles through hostile countries, outwitting cartel gangs, and managing dizzyingly contradictory bureaucracy, all to get to this point: an asylum interview with United States border officials, and almost certain entry.
On its face, this all sounds like a system working in perfect harmony with the needy being helped by a welcoming country.
But in reality, migration is a hotly disputed issue that is likely to dominate the Trump-Harris debate, and the run-up to the presidential election itself.

The group I am with on the bridge is mostly from Cuba, Nicaragua, Haiti, and Venezuela.
They’re claiming asylum, and with their paperwork and appointment email in hand, they approach the border with some trepidation but mostly with excitement and joy.
Many have waited months for their appointment to come through after applying for asylum on the US Customs and Border Protection (CBP) app.
This group of a few hundred people on the bridge are now just a few steps from America.
As they shuffle forward, CBP guards check their papers, make sure there are no errors, and wave them through to the other side for their case interviews.
These families, these children, are about to start a new life.
Along the border here in Matamoros, there’s little sign of Donald Trump’s border wall, but he’d doubtless approve of the razor wire fortifications on the American side of the Rio Grande.
Experts here say there’s no doubt who those seeking asylum are backing in this election and this debate – and that’s Kamala Harris, who is seen to have a far less hostile approach to immigration.
“I think the best would be a flexible US immigration policy again, like President Biden’s when he began his administration,” Oscar Misael Hernandez-Hernandez said as we chatted alongside the dozens of cars and trucks crossing the border.

A professor of social anthropology at the El Colegio de la Frontera Norte research centre and an expert on Mexico-US border issues, he added: “Biden broke with ultra-conservative vision and immigration policy.
“So, I think if Harris implements a migration policy like this if she wins the presidency of the United States, it would be not only quite good for migrants in terms of human rights, but also quite good for international diplomacy, because the relations of the United States, at least with President Trump, if he wins, would be quite disastrous as they were in the past.”
In shelters and hostels across Mexico, many other migrant families simply have to wait for their border appointments.
It’s like a lottery, and it can take a long time for their number to come up.
Few leave the shelter; they would be easy prey for cartel gangs who would kidnap and hold them for ransom.
Marlen Cabrera, 39, from Honduras, and her family are waiting it out along with 200 others at the Casa del Migrante San Francisco de Asis shelter.

Any tightening of the immigration rules – as threatened by Donald Trump – would be a disaster for her.
I asked her what she would do if the laws changed with a Trump victory. She says she doesn’t like to think about what-ifs.
“I’ve been here so long, and not being able to get in would be hard because it’s the only option I have,” she said.
“I have to get in. It would be really terrible if we couldn’t. And I don’t just speak for myself, I speak for everyone here.”
Jose Valdivia, the Nicaraguan manager of the shelter, is even clearer.
“Everybody, since the last election, we all wanted the Democrats to win, right? Because the Democrats look out for the little guy,” he told me.
“That’s what everybody here as a migrant wants, we want the Democrats to win. No one wants Trump.”

Day in, day out, in any weather, the migrants line up for their appointment here at the border in Matamoros.
Along the almost 2,000-mile-long border separating Mexico and the United States, thousands of applicants are screened every day and allowed to enter America legally to start new lives in their new home country.
But these migrants are at the centre of one of the most divisive issues in America right now.
Since the summer, border restrictions introduced by the Biden administration, combined with assistance from Mexican authorities who hamper the movement of migrants to the border, has brought about a large reduction in the number of people illegally entering America.
Despite this, President Biden is widely considered to have failed on immigration, and while Kamala Harris’s team have been working hard to cast her as a sort of new candidate and a breath of fresh air, she is – whether they like it or not – part of this administration and is tainted by its perceived failures.
The latest polls suggest Donald Trump scores well on the immigration issue, and his team have been releasing pointed “attack ads” on Kamala Harris and her team on this subject. They in turn have released adverts attacking Trump.
In the debate itself, Trump is widely expected to try to nail Harris on immigration, and she will have to find a way to counter that.
Undoubtedly, she will point out that Trump’s supporters kiboshed a cross-party action plan for migration, but she is still tainted for certain.
While this will all play out in the political rough and tumble of the electoral process, it is important not to forget that thousands upon thousands of people will be affected by America’s future stance on immigration.
And for some asylum seekers, it is quite literally a matter of life and death.
Russia wants “quick peace” in Ukraine and London is at the “head of those resisting” it, the Russian ambassador to the UK has told Sky News.
In an interview on The World With Yalda Hakim, Andrei Kelin accused the UK, France and other European nations of not wanting to end the war in Ukraine.
“We are prepared to negotiate and to talk,” he said. “We have our position. If we can strike a negotiated settlement… we need a very serious approach to that and a very serious agreement about all of that – and about security in Europe.”

US President Donald Trump held a surprise phone call with his Russian counterpart Vladimir Putin last month, shocking America’s European allies. He went on to call Ukrainian President Volodymyr Zelenskyy a “dictator” and relations between the pair were left in tatters after a meeting in the Oval Office descended into a shouting match.
Days later, the US leader suspended military aid to Ukraine, though there were signs the relationship between the two leaders appeared to be on the mend following the contentious White House meeting last week, with Mr Trump saying he “appreciated” a letter from Mr Zelenskyy saying Kyiv was ready to sign a minerals agreement with Washington “at any time”.
In his interview with Sky News’ Yalda Hakim, Mr Kelin said he was “not surprised” the US has changed its position on Russia’s full-scale invasion of Ukraine, which began in 2022, claiming Mr Trump “knows the history of the conflict”.
“He knows history and is very different from European leaders,” he added.
I’ve interviewed the Russian ambassador to the UK, Andrei Kelin, on a number of occasions, at times the conversation has been tense and heated.
But today, I found a diplomat full of confidence and cautiously optimistic.
The optics of course have suddenly changed in Russia’s favour since Donald Trump was elected.
I asked him if Russia couldn’t believe its luck. “I would not exaggerate this too much,” he quipped.
Mr Kelin also “categorically” ruled out European troops on the ground and said the flurry of diplomatic activity and summits over the course of the past few weeks is not because Europeans want to talk to Moscow but because they want to present something to Mr Trump.
He appeared to relish the split the world is witnessing in transatlantic relations.
Of course the ambassador remained cagey about the conversations that have taken place between President Trump and Vladimir Putin.
There is no doubt however that Russia is welcoming what Mr Kelin says is a shift in the world order.
Peace deal ‘should recognise Russian advances’
The Russian ambassador said Moscow had told Washington it believed its territorial advances in Ukraine “should be recognised” as part of any peace deal.
“What we will need is a new Ukraine as a neutral, non-nuclear state,” he said. “The territorial situation should be recognised. These territories have been included in our constitution and we will continue to push that all forces of the Ukrainian government will leave these territories.”
Asked if he thought the Americans would agree to give occupied Ukrainian land to Russia, he said: “I don’t think we have discussed it seriously. [From] what I have read, the Americans actually understand the reality.”

Moscow rules out NATO peacekeepers in Ukraine
He said Russia “categorically ruled out” the prospect of NATO peacekeepers on the ground in Ukraine – a proposal made by UK Prime Minister Sir Keir Starmer and French President Emmanuel Macron – saying “they have no rules of engagement” and so would just be “sitting in cities”.
“It’s senseless” and “not for reality,” Mr Kelin added.
He branded the temporary ceasefire raised by Mr Zelenskyy “a crazy idea”, and said: “We will never accept it and they perfectly are aware of that.
“We will only accept the final version, when we are going to sign it. Until then things are very shaky.”
He added: “We’re trying to find a resolution on the battlefield, until the US administration suggest something constructive.”
The United States is “finally destroying” the international rules-based order by trying to meet Russia “halfway”, Ukraine’s ambassador to the UK has warned.
Valerii Zaluzhnyi said Washington’s recent actions in relation to Moscow could lead to the collapse of NATO– with Europe becoming Russian President Vladimir Putin‘s next target.
“The failure to qualify actions of Russiaas an aggression is a huge challenge for the entire world and Europe, in particular,” he told a conference at the Chatham House think tank.
“We see that it is not just the axis of evil and Russia trying to revise the world order, but the US is finally destroying this order.”

Mr Zaluzhnyi, who took over as Kyiv’s ambassador to London in 2024 following three years as commander-in-chief of the Ukrainian armed forces, also warned that the White House had “questioned the unity of the whole Western world” – suggesting NATO could cease to exist as a result.

But on the same day, the US president ordered a sudden freeze on shipments of US military aid to Ukraine,and Washington has since paused intelligence sharing with Kyiv and halted cyber operations against Russia.

Mr Zaluzhnyi said the pause in cyber operations and an earlier decision by the US to oppose a UN resolution condemning Russian aggression in Ukraine were “a huge challenge for the entire world”.
He added that talks between the US and Russia – “headed by a war criminal” – showed the White House “makes steps towards the Kremlin, trying to meet them halfway”, warning Moscow’s next target “could be Europe”.
The Rohingya refugees didn’t escape danger though.
Right now, violence is at its worst levels in the camps since 2017 and Rohingya people face a particularly cruel new threat – they’re being forced back to fight for the same Myanmar military accused of trying to wipe out their people.

Militant groups are recruiting Rohingya men in the camps, some at gunpoint, and taking them back to Myanmar to fight for a force that’s losing ground.

Jaker is just 19.
We’ve changed his name to protect his identity.
He says he was abducted at gunpoint last year by a group of nine men in Cox’s.
They tied his hands with rope he says and took him to the border where he was taken by boat with three other men to fight for the Myanmar military.
“It was heartbreaking,” he told me. “They targeted poor children. The children of wealthy families only avoided it by paying money.”
And he says the impact has been deadly.
“Many of our Rohingya boys, who were taken by force from the camps, were killed in battle.”

In Rakhine, just across the border, there’s been a big shift in dynamics.
The Arakan Army (AA), an ethnic armed group has all but taken control of the state from the ruling military junta.

And whilst some Rohingya claim they’re being forced into the fray – dragged back to Myanmar from Bangladesh, others are willing to go.
