A prisoner in Alabama has become the first inmate in the world to be executed with nitrogen gas.
Convicted murderer Kenneth Smith, 58, was put to death after the US Supreme Court declined a legal bid to halt his sentence.
His official time of death was 8.25pm on Thursday (2.25am UK time).
According to witnesses, the execution took about 22 minutes and Smith appeared to remain conscious for several minutes.
For at least two minutes, he appeared to shake and writhe, sometimes pulling against the restraints. That was followed by several minutes of heavy breathing, until breathing was no longer perceptible.
State authorities had predicted unconsciousness within seconds and death within minutes.
In a final statement, Smith said: “Tonight Alabama causes humanity to take a step backwards… I’m leaving with love, peace and light.”
He made the ‘I love you sign’ toward his wife and other family members who were witnesses. “Thank you for supporting me. Love, love all of you,” Smith said.
The use of nitrogen gas is highly controversial and critics say it’s cruel and experimental. It had never been used before anywhere.
It involves clamping a mask tightly to the face, covering the mouth and nose.

The mask is then fed with nitrogen gas. The person continues to breathe normally, but with no oxygen present the body gradually shuts down until death occurs – effectively they are suffocated.
Reverend Jeff Hood, who witnessed the execution, said the reality did not match Alabama’s predictions of a quick death.
“We didn’t see somebody go unconscious in 30 seconds. What we saw was minutes of someone struggling for their life,” he said.
“Heaving back and forth, we saw spit, we saw all sorts of stuff develop from the mask. The mask was tied to the gurney, ripping his head back and forth over and over again.”

Smith was convicted in the 1988 murder-for-hire killing of Elizabeth Sennett.
Prosecutors said he was one of two men who were each paid $1,000 to kill Ms Sennett on behalf of her pastor husband, who was deeply in debt and wanted to collect on insurance.
She was found with eight stab wounds to the chest and one in each side of her neck.
The other killer, John Forrest Parker, was executed in 2010.
In a statement, Alabama state governor Kay Ivey said: “On March 18, 1988, 45-year-old Elizabeth Sennett’s life was brutally taken from her by Kenneth Eugene Smith.
“After more than 30 years and attempt after attempt to game the system, Mr Smith has answered for his horrendous crimes.

“The execution was lawfully carried out by nitrogen hypoxia, the method previously requested by Mr Smith as an alternative to lethal injection.
“At long last, Mr Smith got what he asked for, and this case can finally be put to rest.
“I pray that Elizabeth Sennett’s family can receive closure after all these years dealing with that great loss.”
A new frontier for US execution
Between 7.53pm and 8.25pm last night in the small city of Atmore, Alabama, a 58-year-old man died in a way no human being ever has before.
Kenneth Eugene Smith was strapped to a gurney and had a mask placed over his face. Through the mask, a lethal dose of nitrogen gas was administered.
Until then, it was an untested method to execute a death row prisoner, Smith the definition of a human guinea pig.
Before the execution Alabama state experts had suggested it would take 40 seconds for Smith to be rendered unconscious.
But five media witnesses said that for between two and four minutes, he “shook and writhed” on the gurney and for several minutes after that was breathing heavily.
But the Alabama department of corrections had a different version of events. Ask them how the experiment went and they’ll hail it a success.
“Alabama has achieved something historic,” said state attorney general Steve Marshall.
“Like most states, Alabama has made the judgement that some crimes are so horrific that they warrant the ultimate penalty.
“But anti-death-penalty activists have worked to nullify that moral judgement through pressure campaigns against anyone assisting states in the process.
“They don’t care that Alabama’s new method is humane and effective, because they know it is also easy to carry out.”

Mike Sennett, the son of Smith’s victim, called it a ‘bittersweet day’
Reverend Hood said Smith had a final meal of T-bone steak, hash browns, toast and eggs in steak sauce.
Mike Sennett, the son of Smith’s victim, spoke to media after the execution.
“Nothing happened here today is going to bring Mom back. It’s kind of a bittersweet day,” he said.
“We are not going to be jumping around. whooping and holler, hooray and all that… I’ll end by saying Elizabeth Dorlene Sennett got her justice tonight.”

Smith’s execution comes after he survived a botched lethal injection in 2022 when officials tried unsuccessfully for hours to put an intravenous line into his body.
The incident helped prompt a review of the state’s death penalty procedures.
The Supreme Court justices declined to uphold Smith’s legal challenge that claimed a second execution attempt – after the first failure caused him severe trauma – would violate the US Constitution’s 8th Amendment protections against cruel and unusual punishment.
However the decision was not unanimous, with three justices voting to halt the execution.
“Having failed to kill Smith on its first attempt, Alabama has selected him as its ‘guinea pig’ to test a method of execution never attempted before,” Justice Sonia Sotomayor wrote, saying she would have granted the injunction.
“The world is watching.”
Just minutes before the execution was carried out, the Supreme Court refused for a second time to intervene.
Donald Trump has announced a 10% trade tariff on all imports from the UK – as he unleashed sweeping tariffs across the globe.
Speaking at a White House event entitled “Make America Wealthy Again”, the president held up a chart detailing the worst offenders – which also showed the new tariffs the US would be imposing.
“This is Liberation Day,” he told a cheering audience of supporters, while hitting out at foreign “cheaters”.
He claimed “trillions” of dollars from the “reciprocal” levies he was imposing on others’ trade barriers would provide relief for the US taxpayer and restore US jobs and factories.
Mr Trump said the US has been “looted, pillaged, raped, plundered” by other nations.

His first tariff announcement was a 25% duty on all car imports from midnight – 5am on Thursday, UK time.
Mr Trump confirmed the European Union would face a 20% reciprocal tariff on all other imports. China’s rate was set at 34%.
The UK’s rate of 10% was perhaps a shot across the bows over the country’s 20% VAT rate, though the president’s board suggested a 10% tariff imbalance between the two nations.
It was also confirmed that further US tariffs were planned on some individual sectors including semiconductors, pharmaceuticals and critical mineral imports.

Trump’s tariffs explained
The ramping up of duties promises to be painful for the global economy. Tariffs on steel and aluminium are already in effect.
The UK government signalled there would be no immediate retaliation.
Business and Trade Secretary Jonathan Reynolds said: “We will always act in the best interests of UK businesses and consumers. That’s why, throughout the last few weeks, the government has been fully focused on negotiating an economic deal with the United States that strengthens our existing fair and balanced trading relationship.
“The US is our closest ally, so our approach is to remain calm and committed to doing this deal, which we hope will mitigate the impact of what has been announced today.
“We have a range of tools at our disposal and we will not hesitate to act. We will continue to engage with UK businesses including on their assessment of the impact of any further steps we take.
“Nobody wants a trade war and our intention remains to secure a deal. But nothing is off the table and the government will do everything necessary to defend the UK’s national interest.”

Who showed up for Trump’s tariff address?
The EU has pledged to retaliate, which is a problem for Northern Ireland.
Should that scenario play out, the region faces the prospect of rising prices because all its imports are tied to EU rules under post-Brexit trading arrangements.
It means US goods shipped to Northern Ireland would be subject to the EU’s reprisals.
The impact of a trade war would be expected to be widely negative, with tit-for-tat tariffs risking job losses, a ramping up of prices and cooling of global trade.
Research for the Institute for Public Policy Research has suggested more than 25,000 direct jobs in the UK car manufacturing industry alone could be at risk from the tariffs on car exports to the US.
The Society of Motor Manufacturers and Traders (SMMT) had said the tariff costs could not be absorbed by manufacturers and may lead to a review of output.
The tariffs now on UK exports pose a big risk to growth and the so-called headroom Chancellor Rachel Reeves was forced to restore to the public finances at the spring statement, risking further spending cuts or tax rises ahead to meet her fiscal rules.
A member of the Office for Budget Responsibility (OBR), David Miles, told MPs on Tuesday that US tariffs at 20% or 25% maintained on the UK for five years would “knock out all the headroom the government currently has”.
But he added that a “very limited tariff war” that the UK stays out of could be “mildly positive”.
He said: “There’s a bit of trade that will get diverted to the UK, and some of the exports from China, for example, that would have gone to the US, they’ll be looking for a home for them in the rest of the world.
“And stuff would be available in the UK a bit cheaper than otherwise would have been. So there is one, not central scenario at all, which is very, very mildly potentially positive to the UK. All the other ones which involve the UK facing tariffs are negative, and they’re negative to very different extents.”
Israel is beginning a major expansion of its military operation in Gaza and will seize large areas of the territory, the country’s defence minister said.
Israel Katz said in a statement that there would be a large scale evacuation of the Palestinian population from fighting areas.
In a post on X, he wrote: “I call on the residents of Gaza to act now to remove Hamas and return all the hostages. This is the only way to end the war.”
He said the offensive was “expanding to crush and clean the area of terrorists and terrorist infrastructure and capture large areas that will be added to the security zones of the State of Israel”.
The expansion of Israel’s military operation in Gaza deepens its renewed offensive.
The deal had seen the release of dozens of hostages and hundreds of Palestinian prisoners, but collapsed before it could move to phase two, which would have involved the release of all hostages and the withdrawal of Israeli forces from Gaza.

26 March: Anti-Hamas chants heard at protest in Gaza
The Israel Defense Forces (IDF) had already issued evacuation warnings to Gazans living around the southern city of Rafah and towards the city of Khan Yunis, telling them to move to the al Mawasi area on the shore, which was previously designated a humanitarian zone.
Israeli forces have already set up a significant buffer zone within Gaza, having expanded an area around the edge of the territory that had existed before the war, as well as a large security area in the so-called Netzarim corridor through the middle of Gaza.
This latest conflict began when Hamas launched an attack on Israel on 7 October 2023, killing around 1,200 people and taking around 250 hostages.
The ensuing Israeli offensive has killed more than 50,000 Palestinians, according to Gaza’s Hamas-run health ministry.

Bodies of aid workers found in Gaza
Aid group Doctors Without Borders warned on Wednesday that Israel’s month-long siege of Gaza means some critical medications are now short in supply and are running out, leaving Palestinians at risk of losing vital healthcare.
“The Israeli authorities’ have condemned the people of Gaza to unbearable suffering with their deadly siege,” said Myriam Laaroussi, the group’s emergency coordinator in Gaza.
“This deliberate infliction of harm on people is like a slow death; it must end immediately.”
“Liberation day” was due to be on 1 April. But Donald Trump decided to shift it by a day because he didn’t want anyone to think it was an April fool.
It is no joke for him and it is no joke for governments globally as they brace for his tariff announcements.
It is stunning how little we know about the plans to be announced in the Rose Garden of the White House later today.
It was telling that we didn’t see the President at all on Tuesday. He and all his advisers were huddled in the West Wing, away from the cameras, finalising the tariff plans.
Treasury Secretary Scott Bessent is the so-called ‘measured voice’. A former hedge fund manager, he has argued for targeted not blanket tariffs.
Peter Navarro is Trump’s senior counsellor for trade and manufacturing. A long-time aide and confidante of the president, he is a true loyalist and a firm believer in the merits of tariffs.

The businessman, philanthropist, Trump fundraiser and billionaire (net worth ranging between $1bn and $2bn) has been among the closest to Trump over the past 73 days of this presidency – frequently in and out of the West Wing.
If anything goes wrong, observers here in Washington suspect Trump will make Lutnick the fall guy.

‘Days of US being ripped off are over’
Dancing to the president’s tune
My sense is that we should see “liberation day” not as the moment it’s all over in terms of negotiations for countries globally as they try to carve out deals with the White House. Rather it should be seen as the start.
Trump, as always, wants to be seen as the one calling the shots, taking control, seizing the limelight. He wants the world to dance to his tune. Today is his moment.
But beyond today, alongside the inevitable tit-for-tat retaliation, expect to see efforts by nations to seek carve-outs and to throw bones to Trump; to identify areas where trade policies can be tweaked to placate the president.
Even small offerings which change little in a material sense could give Trump the chance to spin and present himself as the winning deal maker he craves to be.
One significant challenge for foreign governments and their diplomats in Washington has been engaging the president himself with proposals he might like.
Negotiations take place with a White House team who are themselves unsure where the president will ultimately land. It’s resulted in unsatisfactory speculative negotiations.

Treasury minister: ‘We’ll do everything to secure a deal’
Too much faith placed in the ‘special relationship’?
The UK believes it’s in a better position than most other countries globally. It sits outside the EU giving it autonomy in its trade policy, its deficit with the US is small, and Trump loves Britain.
It’s true too that the UK government has managed to accelerate trade conversations with the White House on a tariff-free trade partnership. Trump’s threats have forced conversations that would normally sit in the long grass for months.
Yet, for now, the conversations have yielded nothing firm. That’s a worry for sure. Did Keir Starmer have too much faith in the ‘special relationship’?
Downing Street will have identified areas where they can tweak trade policy to placate Trump. Cars maybe? Currently US cars into the UK carry a 10% tariff. Digital services perhaps?
US food? Unlikely – there are non-tariff barriers on US food because the consensus seems to be that chlorinated chicken and the like isn’t something UK consumers want.
Easier access to UK financial services maybe? More visas for Americans?
For now though, everyone is waiting to see what Trump does before they either retaliate or relent and lower their own market barriers.
