People attend the funeral of a family killed in a Russian missile attack in Ukraine
Donald Trump's special envoy Steve Witkoff and top diplomat Marco Rubio will hold talks with European counterparts in Paris today to discuss efforts to end the war in Ukraine.
The talks - which UK Foreign Secretary David Lammy will also attend - form the highest level of transatlantic engagement about the war since February.
In recent months, the US government has not exactly rushed to consult its European allies.
Thursday's meetings are significant for their happening if nothing else. Witkoff and Rubio will see French President Emmanuel Macron and his team.
The US secretary of state will then hold talks with Lammy along with French and German counterparts. European national security advisers will be involved as well.
The US state department said the focus would be on how to end the fighting in Ukraine and Witkoff would report on his meeting with Russian President Vladimir Putin last week.
European diplomats said they would urge the US to put more pressure on Russia to agree an unconditional ceasefire.
"We want the US to use a bit more stick," one official said.
Watch: White House says man mistakenly deported to El Salvador will 'never' live in US again
The White House has dug in on its refusal to return a man who US officials have acknowledged was wrongly deported last month from Maryland to an El Salvador mega-prison.
Press secretary Karoline Leavitt doubled down on accusations that Salvadoran national Kilmar Ábrego García was a member of the MS-13 gang, which his lawyer denies.
Leavitt also accused the 29-year-old of domestic violence, citing records showing his US citizen wife once filed a protective order against him.
A Maryland judge has ordered President Donald Trump's administration to bring Mr Ábrego García back to the US. But El Salvador President Nayib Bukele said on a visit to the White House this week that he did not "have the power" to return him.
It comes amid an escalating showdown between the president and the judiciary on immigration as a judge in another case said the administration could be held in contempt of court over deportation flights.
Leavitt told a press briefing on Wednesday: "If he [Mr Ábrego García] ever ends up back in the United States, he would immediately be deported again.
"He will never live in the United States of America."
She again accused Mr Ábrego García of being a member of the MS-13 gang, citing court findings. But his lawyer and family reject that he was ever in the gang.
The press secretary also called Mr Ábrego García a "woman beater", referring to a domestic violence claim.
The Department of Homeland Security released details of a 2021 restraining order filed by his wife, who alleged he punched and scratched her and ripped off her shirt.
Mr Ábrego García's wife, Jennifer Vasquez Sura, told Newsweek on Wednesday that she sought the order "out of caution". She said they were able to resolve the situation as a family, including by counselling.

Kilmar Abrego Garcia was deported on 15 March
The BBC contacted Mr Ábrego García's lawyer, Benjamin Osorio, about the domestic violence allegation.
The attorney responded by email: "Is the government allowed to admittedly break the law if an individual is alleged to have broken the law?"
Mr Ábrego García was living in Maryland, before he was deported on 15 March with scores of Salvadorans and Venezuelans to the Center for the Confinement of Terrorism (Cecot) in El Salvador.
Maryland Judge Paula Xinis ruled that Mr Ábrego García's removal from the country breached a 2019 court order that had granted him legal protection from deportation.
The US Supreme Court last week partially upheld the lower court ruling, finding that the Trump administration must "facilitate" Mr Ábrego García's release.
Trump administration officials have conceded the deportation was an "administrative error", although the White House insists there was no mistake.
Judge Xinis has requested daily updates on what steps are being undertaken to bring him back to the US.
But in Wednesday's status report, acting general counsel at the Department of Homeland Security Joseph Mazzara told the court there were "no further updates".
The White House press secretary was joined at Wednesday's briefing by the mother of a Maryland woman who was murdered in August 2023 by an alleged illegal immigrant from El Salvador.
Patty Morin shared graphic details of her daughter Rachel Morin's death at the hands of Victor Martinez-Hernandez, who was found guilty on Monday.
"We are American citizens," said Patty Morin. "We need to protect our families, our borders, our children."

Meanwhile, Maryland Senator Chris Van Hollen, a Democrat, flew to El Salvador in an attempt to speak with Mr Ábrego García, but was denied access on Wednesday.
Van Hollen met the country's Vice-President Félix Ulloa, who told the US senator they could not accommodate a visit to the mega-prison.
In a press conference in the capital San Salvador, Van Hollen called on the Central American country to release "a man who's charged with no crime, convicted of no crime and who was illegally abducted from the United States".
The White House hit back in a press release that Van Hollen "didn't even bother to contact" the family of Rachel Morin after her death.
Van Hollen's rebuff came a day after another US member of Congress, West Virginia Republican Riley Moore, was allowed by Salvadoran authorities to enter the prison.
Moore posted a selfie in front of a crowded cell, saying the visit had made him even more determined to "support President Trump's efforts to secure our homeland".
Harvard President Alan Garber has flatly rejected the White House's sweeping list of demands
The US government has threatened to ban Harvard University from enrolling foreign students, after the institution said it would not bow to demands from Donald Trump's administration.
The White House has demanded the oldest university in the US make changes to hiring, admissions and teaching practices which it says will help fight antisemitism on campus.
Homeland Security Secretary Kristi Noem on Wednesday accused the Ivy League school of "threatening national security" and "bending the knee to antisemitism".
She also demanded records on its foreign student visa holders' "illegal and violent" activities. International students make up more than 27% of Harvard's enrolment this year.
"The university will not surrender its independence or relinquish its constitutional rights," Harvard President Alan Garber wrote in a message on Monday to the Harvard community.
Billions of dollars hang in the balance for the university - authorities have frozen $2.2 bn (£1.7bn) in federal funds, while Trump earlier threatened to also remove a valuable text exemption, the loss of which could cost Harvard millions of dollars each year.
"Harvard can no longer be considered even a decent place of learning, and should not be considered on any list of the World's Great Universities or Colleges," Trump said on his Truth Social platform on Wednesday.
"Harvard is a JOKE, teaches Hate and Stupidity, and should no longer receive Federal Funds."
The administration's attacks on Harvard are not isolated.
During his presidential campaign, Trump pitched a funding crackdown on universities, painting them as hostile to conservatives.
Since taking office, his administration has focused particularly on colleges where pro-Palestinian protests have taken place. Some Jewish students have said they felt unsafe and faced harassment on campus.
The government's antisemitism task force, formed in February, has identified at least 60 universities for review.
In March, Columbia University, agreed to several of the administration's demands, after $400m (£310m) in federal funding was pulled over accusations the university failed to fight antisemitism on campus.
These included replacing the official leading its Middle Eastern, South Asian and African Studies department and pledging to take on a review to "ensure unbiased admission processes".
Harvard too has made concessions.
Last month, it dismissed the leaders of its Center for Middle Eastern Studies, who had come under fire for failing to represent Israeli perspectives.
Harvard has not publicly responded to Noem's latest demands.
Artwork of K2-18b, a faraway world that may be home to life
Scientists have found new but tentative evidence that a faraway world orbiting another star may be home to life.
A Cambridge team studying the atmosphere of a planet called K2-18b has detected signs of molecules which on Earth are only produced by simple organisms.
This is the second, and more promising, time chemicals associated with life have been detected in the planet's atmosphere by Nasa's James Webb Space Telescope (JWST).
But the team and independent astronomers stress that more data is needed to confirm these results.
The lead researcher, Prof Nikku Madhusudhan, told me at his lab at Cambridge University's Institute of Astronomy that he hopes to obtain the clinching evidence soon.
"This is the strongest evidence yet there is possibly life out there. I can realistically say that we can confirm this signal within one to two years."
Could this faraway world be home to life?
K2-18b is two and a half times the size of Earth and is seven hundred trillion miles away from us.
JWST is so powerful that it can analyse the chemical composition of the planet's atmosphere from the light that passes through from the small red Sun it orbits.
The Cambridge group has found that the atmosphere seems to contain the chemical signature of at least one of two molecules that are associated with life: dimethyl sulphide (DMS) and dimethyl disulphide (DMDS). On Earth, these gases are produced by marine phytoplankton and bacteria.
Prof Madhusudhan said he was surprised by how much gas was apparently detected during a single observation window.
"The amount we estimate of this gas in the atmosphere is thousands of times higher than what we have on Earth," he said.
"So, if the association with life is real, then this planet will be teeming with life," he told me.
Prof Madhusudhan went further: "If we confirm that there is life on k2-18b it should basically confirm that life is very common in the galaxy".

The James Webb Space Telescope is powerful enough to analyse the atmosphere of planets that are hudreds of trillions of miles away
There are lots of "ifs" and "buts" at this stage, as Prof Madhusudhan's team freely admits.
Firstly, this latest detection is not at the standard required to claim a discovery.
For that, the researchers need to be about 99.99999% sure that their results are correct and not a fluke reading. In scientific jargon that is a five sigma result.
But even if the Cambridge team obtains a five sigma result, that won't be conclusive proof that life exists on the planet, according to Prof Catherine Heymans of Edinburgh University and Scotland's Astronomer Royal, who is independent of the research team.
"Even with that certainty, there is still the question of what is the origin of this gas," she told BBC News.
"On Earth it is produced by microorganisms in the ocean, but even with perfect data we can't say for sure that this is of a biological origin on an alien world because loads of strange things happen in in the Universe and we don't know what other geological activity could be happening on this planet that might produce the molecules."
That view is one the Cambridge team agree with; they are working with other groups to see if DMS and DMDS can be produced by non-living means in the lab.
Other research groups have put forward alternative, lifeless, explanations for the data obtained from K2-18b. There is a strong scientific debate not only about whether DMS and DMDS are present but also the planet's composition.
The reason many researchers infer that the planet has a vast liquid ocean is the absence of the gas amonia in K2-18b's atmosphere. Their theory is that the ammonia is absorbed by a vast body of water below . But it could equally be explained by an ocean of molten rock, which would preclude life, according to Prof Oliver Shorttle of Cambridge University.
"Everything we know about planets orbiting other stars comes from the tiny amounts of light that glance off their atmospheres. So it is an incredibly tenuous signal that we are having to read, not only for signs of life, but everything else.
"With K2-18b part of the scientific debate is still about the structure of the planet," he said.
Both these alternative interpretations have also been challenged by other groups on the grounds that they are inconsistent with the data from JWST, which highlights the strong scientific debate surrounding K2-18b.
Prof Madhusudhan acknowledges that there is still a scientific mountain to climb if he is to answer one of the biggest questions in science. But he believes he and his team are on the right track.
"Decades from now, we may look back at this point in time and recognise it was when the living universe came within reach," he said.
"This could be the tipping point, where suddenly the fundamental question of whether we're alone in the universe is one we're capable of answering."
The research has been published in The Astrophysical Journal Letters.
King Charles talked of humanity's capacity for both great cruelty and kindness
King Charles has issued an Easter message trying to build bridges between different faiths and recognising the efforts of those who provide humanitarian aid in wars and disasters.
"One of the puzzles of our humanity is how we are capable of both great cruelty and great kindness," said the King, in a message ahead of the traditional Maundy Service, held this year in Durham Cathedral.
The King and Queen Camilla will attend the service in which specially minted coins, the Maundy Money, are presented to 76 men and women, the same number as the King's age.
The King has promoted links between different religions - and this Christian message also praises the goodness in the Jewish and Islamic faiths.
In his message on the meaning of Easter, the King talks of the "paradox of human life" in which the heroism of humanitarian workers is contrasted with terrible scenes of suffering in war.
A new Humanitarian Medal has been launched, honouring those who risk their own lives to help others in emergencies and war zones, and the King hailed their selflessness and compassion.
For Christians, the Maundy Thursday service marks the Last Supper - and the King's message speaks of the humility of Jesus who "knelt and washed the feet of many of those who would abandon him".
The King said that for people of all religions who "seek the good of others" the core message is one of love for others.
"There are three virtues that the world still needs - faith, hope and love. And the greatest of these is love," said the King's message.
King Charles is a man of faith and was said by Palace officials to have been deeply moved by the religious mosaics he saw in Ravenna on last week's state visit to Italy.
The King missed last year's Maundy Service because of his cancer treatment, with the Queen giving out the Maundy Money on his behalf.
This year's Maundy coins will include a £5 one commemorating the Queen Mother and a 50p commemorating World War Two, with the recipients being people who have helped their local churches and community.
This is one of the oldest royal ceremonies, dating back at least as far as the 13th Century and the reign of King John.

Gold has jumped to a fresh record high as investors fret over the impact of the trade war between the US and China.
Spot gold touched $3,357.40 (£2,540) per ounce on Wednesday, before dipping from its peak. It has risen by around 30% since the start of the year.
The latest move comes after the head of US central bank said President Donald Trump's tariff policies are likely to mean slower growth and higher prices.
The precious metal is viewed as a safer asset for investors during times of economic uncertainty.
In remarks for the Economic Club of Chicago on Wednesday, Federal Reserve Chair Jerome Powell said the higher-than-expected tariffs announced in recent weeks are likely to mean US economic growth will slow and rising prices for consumers.
The comments come after a period of turmoil on global financial markets as investors reacted to the new import taxes coming into effect and the escalating trade war between the US and China.
Gold is in "full lifeboat mode" as it has become "the most crowded trade on the planet," Stephen Innes from the SPI Asset Management firm said.
"The dollar is stumbling under the weight of trade-policy whiplash, and portfolio managers have lost faith in anything that involves political discretion," he added.
Analysts have compared this year's gold rally to the Iranian Revolution more than four decades ago, when prices jumped by almost 120% from November 1979 to January 1980.
Jesper Koll from advisory firm Monex Group said investors have flocked to gold as "a trust hedge against both inflation and government recklessness".
"Everyone is looking for 'real' assets. It's increasingly clear that Team Trump's 'move fast and break things' approach to policy making will not change," he added.
The introduction of tariffs by the Trump administration, which are taxes charged on businesses importing goods from overseas, has fuelled fears of inflation, which has driven investors to so-called safe haven assets like gold.
Trump has put taxes of 145% on China since he returned to the White House in January, and China has retaliated with a 125% tariff on US imports.
There is also uncertainty about whether sweeping US tariffs on a host of other countries will go into effect, after being paused for 90 days.
The Trump administration has said the measures will bring manufacturing back to the US, create jobs for American workers and generate billions of dollars of tax revenues.

The UK government has brought in a temporary ban on holidaymakers bringing in cheese and meat products from the EU in a bid to prevent the spread of foot-and-mouth disease.
Travellers have not been allowed to bring back items such as cured and cheese, including in sandwiches, since Saturday due to the growing outbreak on the continent.
The restrictions apply regardless of whether the goods are packed or packaged, or bought from duty free.
It follows an earlier ban of similar products from Germany, Hungary, Slovakia and Austria after rising cases of the cattle disease in those countries.
The restrictions apply to people arriving in Great Britain, not Northern Ireland, Jersey, Guernsey, or the Isle of Man.
Products will be seized and destroyed if people try to bring them in, and in "serious cases" people could be fined up to £5,000.
The list of restricted products includes:
pork
beef
lamb
mutton
goat
venison
other products made from these meats, for example sausages
milk and dairy products like butter, cheese and yoghurt
People can bring up to 2kg per person of powdered infant milk, infant food, or special food needed for medical reasons.
There are currently no cases of foot-and-mouth disease in the UK.
The Texas House approved the plan, part of a push by President Trump’s allies to offer up to about $10,000 for private school, home-school or virtual learning.

One of the most unnerving experiences with a Mac is to discover that it has either restarted and is waiting for you to log in, or has shut itself down completely. This article explains what might have happened, and how you can distinguish between those causes.
Power failure
The commonest single cause for these events is loss of power to the Mac’s internals, which could mean anything from the mains power supply or internal battery through to the Mac’s power supply unit (PSU). Even if your Mac is up and running fine again, and supplied by an uninterruptible power supply (UPS), confirm that there hasn’t been a power glitch. Any good UPS should keep an event log that you can check to see whether there was anything untoward.
Intermittent PSU faults are rarer but can be tricky to diagnose, and hardware diagnostics may fail to pick them up. If you don’t have any evidence that anything went wrong with power supply, put it to the bottom of the list for the moment. However, if you suspect your Mac’s PSU might be defective in any way, don’t use it again until a trained Apple technician has checked it carefully and assured you that it’s safe. Mains power still kills many people, including those who should know better.
Other hardware faults
There’s a long list of other hardware causes, from a defective system management controller (SMC) to faulty memory. If your Mac is getting long in the tooth or has shown other signs suggesting it might have a hardware problem, now is the time to run hardware diagnostics to check. But if it has been working fine, move this lower down in your list, to return to later if other causes aren’t evident.
Kernel panic
macOS is designed to keep its kernel running through thick and thin, even when apps are crashing all around it. Sometimes, though, the most robust of kernels can reach a point of no return, and it should then panic, allowing the Mac to restart (or in some older Macs, shut down) and try again. That’s a better option than everything grinding to a halt in a ‘freeze’, when you have to force the Mac to shut down by pressing and holding the Power button, which may not result in production of a panic log.
Shortly after starting up following a kernel panic, you should be offered the panic log, as I’ve described elsewhere. But what do you do if you think it might have been a panic but don’t see any dialog offering a log? Your next move depends on whether it’s an Apple silicon Mac or an Intel model.
Intel: cause codes
When an Intel Mac starts up (including following a restart) or wakes from sleep, the reason for the previous shutdown (or initiation of a restart) or sleep should be reported in the log as a cause code. In El Capitan and earlier versions of OS X, you can find recent cause codes in the logs using Console: search for shutdown cause, or sleep cause when looking for a wake event instead. From Sierra onwards, you’ll need to check the unified log; in macOS 14.6 and later, that’s simplest using LogUI. Set its Predicate menu to read eventMessage, and enter shutdown cause in the text box to the right. Ensure the time period includes the first few seconds of the boot or reboot, and you should then be presented with an entry similar to: 2025-04-16 19:48:55.630+0100 kernel Previous shutdown cause: 5
Negative cause codes refer to hardware causes originating mainly from the SMC, and positive codes refer to software. A special code of 0 indicates an intermediate, which can occur when there’s sudden loss of power on some systems.
Among the hardware cause codes, the following are notable:
-3 multiple temperature sensors too high
-61, -62 unresponsive app resulting in forced shutdown
-64 kernel panic
-71 memory too hot
-74 battery too hot
-75 MagSafe power adaptor communication problem
-78 incorrect input current from power adaptor
-79 incorrect current from battery
-86, -95 proximity temperature (heatsink etc.) too high
-100 power supply too hot
-101 display too hot
-103 battery voltage too low
-104 unknown battery fault
-127 PMU/SMC forced shutdown for another cause
In the software cause codes, there seem to be only two that occur commonly:
3 is a ‘dirty’ shutdown resulting from a forced restart or shutdown
5 is a ‘clean’ shutdown initiated by the user.
You can find a more detailed list on George Garside’s blog. However, these don’t appear to be given for Apple silicon Macs, and even Intel models don’t seem as reliable at writing them to the log now.
Apple silicon: hunt the panic
Although you can try finding a log entry giving a cause code, I’ve not been successful yet on an Apple silicon Mac, where you have to look for other clues as to whether the cause was a kernel panic. Those include:
Look for /var/db/com.apple.DumpPanic.panicLogPathBreadcrumb. If that file exists, drag-copy it to your Documents folder and open it with a text or property list editor. It should contain a single dictionary, with a UUID key and a string. If that’s empty, there’s no panic log, otherwise it may give you a further clue.
Look for the word paniclog in the eventMessage field for log entries in the minute or two after the Mac restarts. If that extract reads failed to map memory for paniclog output - 0x3 then there’s likely to be a panic log somewhere.
Browse log entries from the subsystem com.apple.DumpPanic in the minute or so after startup. That subsystem handles generation of the panic log, and makes it clear whether there is one.
From bitter experience, I regret to inform you that trying to gain any information about a kernel panic, or its cause, from log entries made before the Mac shut down or restarted are almost certainly doomed. In any case, most of the time you don’t know when the Mac shut down or restarted, so would waste time trying to discover that.
DumpPanic
In an Apple silicon Mac, at least, if there are log entries from com.apple.DumpPanic confirming that a panic log was generated, you’ve struck gold, even if you can’t find the log itself. Make a note of the time that subsystem reports DumpPanic launched after boot to check for device panic data
then use that as the start time for a log extract set to a subsystem of com.apple.osanalytics.preoslog, and examine those entries. Starting with the entry preoslog dump begin
you’ll see breadcrumb data from iBoot stages 1 and 2, each introduced with the emoji , and ending with preoslog dump end
A little further on, com.apple.DumpPanic should give the first line of the panic log, such as embedded panic string decoded: panic(cpu 0 caller 0xfffffe002513b34c): Kernel data abort. at pc 0xfffffe0025acf058, lr 0x70c77e0025acf40c (saved state: 0xfffffe8dff723310)
Even if you can’t see the full panic log, at least you’ve got its punchline.
不过我也不是 AI 吹：
如果让我不依赖 AI 的话，整个过程可能只会从 3 小时增加到 1 、2 天。
如果是一个不懂编程的人，他应该也能在 1 天内利用 AI 完成，但是因为缺少相关的体系知识，细节和实现效率就不会打磨了。
所以目前看来，AI 还不能取代程序员。但学习那些 AI 不擅长的知识，与 AI 做个互补，可能是程序员未来最优的路。
