We heard a bit there of some of the criticism Donald Trump's been receiving over this, but obviously, you know, if there's anyone who shrugs off criticism well, it is Donald Trump. Do you think it's likely he'll pay attention to this?

Well, that's right. And very unlikely, I would think, President Trump has made curbing illegal immigration the centerpiece of his second term in office. He's vowed to deport millions of people who are in this country illegally, despite growing accusations of authoritarian overreach. And he continues to blame state officials for, as he sees it, failing in their duty to protect ICE agents.

who were simply trying to do their job and enforce the law. Mr. Trump has threatened several times in recent months to implement the Insurrection Act in response to court decisions that have blocked his attempts to deploy the National Guard in some parts of the country, and asked if the president was serious about invoking the Insurrection Act. The Homeland Security Secretary, Kristi Noem,

She said she didn't know, but she added that it was his constitutional right. David Willis in Washington. Families of protesters killed in Iran have told the BBC the authorities are demanding large sums of money for the return of bodies. Relatives say they're being asked to hand over thousands of dollars so they can bury their loved ones. In some cases hospital staff have been warning people to collect bodies before they can be seized by the security forces.

One human rights group says more than two and a half thousand people have been killed in the unrest. First-hand accounts of what's been happening in Iran are hard to come by, given the communication difficulties and the need for safety of those who want to speak freely. But the BBC has heard an eyewitness account of shocking brutality from an Iranian living in the UK who was back in her home country last week.

She wasn't in a big city, but had clear sight of the events in the town in which she was staying from her family's balcony on the fourth floor. We're calling her Puna, which is not her real name, and we're not giving the name of the town. We've also revoiced her answers to protect her identity. She started by describing to my colleague Evan Davis the violent events she witnessed a week ago.

8.1. oli noin 8-9 huhtikuuta, jotain näin. Ihmiset, erityisesti nuorten ihmiset, menivät ulkopuolelle protestaatioon. He olivat hyvin rauhoittuneita. Kun puhuimme heille, että heidän pitäisi ottaa huolta, he sanoivat, että emme saa mitään pahaa. He sanoivat, että ekonomi on niin pahaa, että tilanne on niin pahaa, että inflaatio on niin pahaa, että emme saa mitään toivoa tulevaisuudelle.

We were observing this, yes. We're not the active protesters. We were observing it from the balcony. So we went to sleep and it was about 2.45 a.m. that we woke up with horrible, horrible shooting noises. And when we went to the balcony, we saw that there were some people, I'm not sure, the IRGC, police or other people, their faces were totally covered. They were shooting people.

Se on ihan kuten komppuutiohjelmien kanssa. Jätetään, he jättävät. Jätetään, he jättävät. Jätetään, he jättävät.

I was shouting saying, I want to call an ambulance. They were saying that all the ambulances are under the control of the police. If the ambulance comes, this person will never get to the hospital. What was the talk in the town the next day? Obviously something very, very traumatic has happened to a town.

Seuraavana päivänä kaupungissa näimme monia nuoria kaupungilla. Kysyimme heitä, mitä tapahtui. He eivät voineet puhua. Se on niin horifikki, koska moni heidän ystävänsä oli kuullut.

Ymmärrätkö, ettei täällä ole niin paljon ihmisiä. Kaikki, joiden puhuttiin, sanoivat, että ystäväni pysähtyi, kun he olivat syötäneet yläpäivääni. Ja sitten toinen päivä, 9.1., he aloittivat syötämään ihmisiä suoraan heidän kanssaan. Oli melkein 10 tai 11 päivää. Ehkä vain yksi tunti sitten, kun protesit alkoivat.

There were people on the back of a Toyota, you know, just like ISIS, something like this. And they're shouting, if you're brave enough, come out, come out and see what will happen to you. They were going in all the alleys, in all the streets, and they were shouting to people to come out. And it was something, you know, for example, imagine this 19 years old boy. They followed him with a Toyota, and they found him in a dead end and shot him. I think they had some orders that gave them more freedom to do whatever they wanted to do.

You came out of Iran. How much contact have you had with your friends and relatives? What are they saying now about what's happening? Are the protests still ongoing? In the small towns from where we were in the north, after the second night and the third night, they're saying that the armed forces are so dominant in the town. My mum was saying that I am seeing more armed forces than ordinary people.

One family was mourning a young dead loved one.

Right, a fact for you now. We know more about the surface of some planets in our solar system than we do about what lies between the vast ice of Antarctica. But researchers are making breakthroughs. They've developed a new map of the continent's underbelly, revealing thousands of previously undiscovered hills and ridges. They hope the research, published in the academic journal Science, will improve understanding of how the continent might respond to climate change. The study's lead author is Helen Ockenden.

With more details, here is our climate reporter Mark Pointing. Thanks to data collected by satellites, scientists have a good understanding of Antarctica's icy surface. But what lies beneath has remained more of a mystery. In fact, more is known about the surface of some planets in our solar system than much of what's under the continent's ice. Now researchers have used a new approach to create what they believe to be the most detailed map of the landscape yet.

The ridges, mountains and channels shape how fast the glasses above move, and understanding the topography could help scientists work out how quickly the ice might retreat in a warming climate. The scientists say more research is needed to give greater confidence in their findings, but they hope the new map will ultimately improve understanding of the potential impact on sea levels from Antarctica's melting ice.
