You're going to be flying helicopters in and out of there to get the resupply going. It's just a very logistically challenged piece. I've been speaking to our diplomatic correspondent James Landale. I asked him first, what's the strategy behind President Trump now focusing on Karg Island?

This is a huge source of revenue for Iran's economy. Iran's economy is already in bits. It has been struggling for a very, very long time. And the argument is that if the Americans can control that island, then they can put pressure on the Iranian regime in talks, particularly in discussions to open up the Strait of Hormuz. So in other words, it would in theory give the Americans some leverage.

And if there were US troops on Karg Island, I mean, they would be very easily reached by Iranian missiles, Iranian artillery. I mean, would they be sitting ducks in a way?

Well, yes and no. I mean, first of all, the Americans would have to take it, and that's no mean feat. It's a long way from anywhere. Remember, the Strait of Hormuz is highly defended, so there's a question mark about whether or not the Americans could get any warships into the Gulf. Then you've got the question of how the Americans could hold Karg Island. It would require substantial resupply in terms of soldiers, munitions, emergency medical evacuation.

Militaarit voivat kertoa, että se on ollenkaan mahdollista, mutta kuten aiemmin, the longer you hold any island or piece of ground militarily, the harder it becomes to defend it in the long term, because the cost will mount. He also talk about the possibility of going into Iran and seizing the uranium.

Kyllä, niin katsotaan. Siinä on noin 400 kilogrammaa vahvasti vahvistettua uraniumia, joka on pysynyt. Tämä on jäljellä Suomessa israelilaisen vahvistuksen Iranin viikolla. Ja tämä on materiaali, joka on melko kovin vahvista materiaalia. Voit todennäköisesti...

Just enrich it a little bit further, make the experts estimate about 10 to 12 bombs. And the suggestion is that the Americans might try to conduct some kind of special forces operation to seize and remove this material. But again, the military experts are all warning this would be hugely complex material.

Has President Trump got himself in a bit of a mess here? Because it doesn't appear like there's an exit strategy. He's very mixed with all his messages. You know, what is going on? Well, sometimes the American messaging is deliberately mixed to confuse the enemy. And therefore, on the one hand, the Americans are suggesting a willingness to talk, but on the other hand, they're suggesting a willingness to escalate and deploy military force in different ways.

One level that's designed to keep the Iranians guessing. It's also designed to try and put pressure on the Iranians to say, look, if you don't agree to some kind of deal over reopening the Strait of Hormuz, then the Americans are willing in theory to deploy greater military force and to escalate. The risk though is, A, the element of surprise has gone because Donald Trump has been speaking so openly about some of these potential options that he might deploy.

But also, as you say, there is still a degree of strategic confusion over how the Americans wish to exit this war. And at the moment, there's not a great deal of clarity coming out of the White House.

That was James Landale.

As Israel continues to carry out attacks across Iran damaging power grids, life for ordinary people there is getting harder by the day. Our correspondent Jo Inwood has compiled this report.

Työntekijänä, tutkimus- ja terveysyhteyksikön työntekijä kävelee suurelta rannalla Tiranin keskellä. Terveysyhteyksikön lämpö paistaa moottorin jälkeen, ennen kuin jatketaan. Tämä on tullut yleinen tapauksena, kun Yhdysvallat ja Israelit laittavat viimeisenä viikonloppuna. Yksi naisi, joka elää lähellä, näyttää myötätuntoa.

Tämä historiallinen pizazio ja markkinointi näyttävät sattuneita, mutta eivät ole tyhjentäisiä, kuten järjestäjien kuvauksissa. Kulmattomia kukkoja on rauhoittunut. Joku rauhoittaa uusia pomegranatejuutia. Vain yksi ihminen puhuu kameralla. Matin, joka on tietoprogrammattori. Hän näyttää olevan 20-vuotias, ja hänellä on pakko, joka on ylöspäin. Me olemme vahvistamassa.

We are fighting to prevent sanctions to show the strength of the country, of our country, he says. For me, these things are more important than internet outages or anything else. But that message of defiance is not what you always get in private communications, as shared with BBC Persian News and voiced by their team. My businesses are completely shut down now. My situation is not better than theirs.

Just as getting information out of Iran is difficult because of the near total internet shutdown, so too is it hard for Iranians to hear from the outside world. But clearly, information does get in. Over the weekend, President Trump said this. They have to open it up. They have to open up the strait of Trump. I mean, Hormuz. Excuse me. I'm so sorry.

Nyt, jos tai ei se olisi jokainen, se vaikuttaa seuraavasti Iranilaisille, jopa niille, jotka opettavat regiimiä. Trump kutsuttiin Hormonin rautaa Trumpin rautaan. Hormonin rautaa ja Iranilaiset ovat vahvistuneet. Viime viikolla Teheranissa oli yllättävää ääntä, todennäköisesti niille, jotka katsoivat tämän maan ulkopuolella.

Iranian airdefenses firing into the black sky. They appear to be aging AA guns, unlikely to shoot down a modern fighter jet, but they are still firing. In what is fast becoming a battle of wills, that is significant.

Joe Inwood reporting. Russia has come to the aid of Cuba and sent more than 700,000 barrels of oil to the communist island, which has been suffering under a US oil blockade. The Kremlin spokesman Dmitry Peskov said it had raised the issue with the United States and was pleased the sanctioned delivery was taking place.

Now, if you're someone who prides yourself on being an early riser, fresh and chirpy in the morning, spare a thought for your opposite numbers who prefer being up late into the night. Because researchers in Italy have found that night owls are more likely to show signs of being depressed, anxious and irritable.
