At least 40 demonstrators and five security personnel have been killed. And President Trump has threatened to strike Iran very hard if the authorities continue to kill those demonstrating. Our World Affairs correspondent Caroline Hawley has more details.

GR Gold from the BBC's Persian Service. Protests have been spreading in the United States over the fatal shooting of a woman by a federal immigration agent on Wednesday. Thousands of people marched through the streets of Minneapolis, close to where Rene Good, an American citizen, was shot, chanting slogans against immigration enforcement or ICE. These residents were vocal in their opposition.

Hundreds of people also gathered at demonstrations in New York and Philadelphia. The incident has sharpened the already intense political divide across the US. Officials have offered differing accounts of her killing, with the Trump administration claiming the ICE agent was acting in self-defense, while local officials say the woman posed no danger. Here's the vice president, J.D. Vance.

Officials in the US state of Minnesota say the FBI has cut them out of the investigation into the incident and that the inquiry will be neither transparent nor fair without the involvement of local law enforcement officials. But the Homeland Security Secretary Kristi Noem said they had no jurisdiction over the case. State Governor Tim Walz said the people in the Trump administration had already passed judgment.

Well, during his election campaign, President Trump promised the largest deportation program in American history, and he placed ICE at the center of his immigration policies. The agency has deported hundreds of thousands of people in recent months, but critics say that it's acting as a paramilitary organization. So how did the American public feel about what's going on? That's a question I put to our North America editor, Sarah Smith.

The US agency said the astronaut was in a stable condition but gave no further details on the grounds of privacy. Space journalist Richard Hollingham says such events are a reality when human beings are in space.

So what's it like looking after your health in space? Clayton Anderson spent 152 days on board the ISS back in 2007. He spoke to the BBC's Evan Davis.

Ja siksi se on minulle huomio, että pitkän aikavälin missioita maailmalle tai Marsille, tarvitaanko lääkärin? Tarkoitukset, jos ne eivät ole käsitellyt, voivat olla väärässä. Ja ne voivat tapahtua jossain määrästä. Ja ajattelen, että onko se vain aikaa, kun jotain näin tapahtuu. Et ole vain siellä kaksi päivää, vaan monta päivää, ennen kuin joku saa sellaisen jakson. Ei ole sellaista infektiivisuutta, ei ole sellaista virusia. Kardiakki-jakson, esimerkiksi. Nämä ovat kaikenlaisia, olisin ajatellut.

Kuinka kauan tarvitaan ilmaisuudessa tuoda kruun tai kruun jäsenen kotiin Space Stationista? Mikä on nopeimpi, että heidät voidaan saada terveydenhuoltoon 400 kilometriä yli? Se olisi vaihtoehto, joka riippuu siitä, kuinka monimutkaisesti ja missä tarkoitettiin aloittaa.

Still to come in this podcast. Many of the best ideas have been generated during periods of fallowness and boredom. So I feel like mindfulness has had a rebrand and it was boredom's turn. Why boredom is a good thing.

Venezuela's interim government has released a number of political prisoners calling it a goodwill gesture. It was announced by the president of the National Assembly, Jorge Rodriguez.

The release of the prisoners comes just days after US forces seized the former president, Nicolas Maduro, and declared that the US administration was now in charge of Venezuela. Norberto Paredes from BBC Mundo was outside the prison in Caracas.

Will Grant is our Central American and Caribbean correspondent. It's been one of Washington's demands for a long time. Anytime there's heightened repression in Venezuela, particularly around contested elections, around protests around those same elections,

Washington has urged the Venezuelan government to release political prisoners. Of course Mr. Rodriguez said it was a sort of unilateral step by the Venezuelan government, but the suspicion is that of course this comes under pressure from Washington. We don't know the identities or the numbers of those who are currently being released, but NGOs in Venezuela believe 1,011 people have been detained over the years because of their political leanings.

There is a very notorious, very well-known detention center, an alleged torture center in Caracas called Elecoide. And one human rights group, amid rumors and unverified information at this stage that it is currently being shut down, said, look, there are other centers in the country. They want to see a genuine change after Nicolas Maduro has been removed from office by the Americans.

Meanwhile, Colombia's president, Gustavo Petro, has told the BBC he believes there is a real threat of US military action against his country after the strikes on Venezuela and the seizing of Nicolas Maduro. President Trump has said a military operation in Colombia sounds good to me. Our South America correspondent, Ioni Wells, sent this report from the Colombian capital, Bogota.

These two world leaders have long been adversaries, frequently trading insults and threats on social media. Since the US's military operation in Venezuela last Saturday, Donald Trump has suggested several times that Colombia is also in his sights, telling President Petro in ruder language to essentially watch his back. I asked Mr. Petro how seriously he was taking these threats and if he was afraid for his own security.

Mr Trump, as he did with Nicolás Maduro, has accused Mr Petro of being personally involved in trafficking cocaine, which he strongly denied, saying that it had always been proven that he was not involved in that. His critics have accused him of failing to tackle cocaine production, which has hit record highs in recent years.

Now put down your phones. It's no secret that there's been growing anxiety about what social media or always being online is doing to our brains. But could one way of giving our often overworked and overstimulated minds a break be boredom?

It's become a recent trend on social media with people filming themselves doing absolutely nothing, otherwise called raw dogging. So what are the advantages of boredom, and how does it change the way your brain works? Sarah Montagu spoke to Helen Russell, an author who recently wrote a piece entitled The Quiet Rebellion of Doing Nothing, and Dr Sandy Mann, a senior psychology lecturer at the University of Lancashire here in England, who wrote a book called The Science of Boredom,
