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 agreed to send “top of the line weapons” to NATO to support Ukraine – and threatened Russia with “severe” tariffs if it doesn’t agree to end the war.
Speaking with NATO secretary general Mark Rutte during a meeting at the White House, the US president said: “We’ve made a deal today where we are going to be sending them weapons, and they’re going to be paying for them.
“This is billions of dollars worth of military equipment which is going to be purchased from the United States,” he added, “going to NATO, and that’s going to be quickly distributed to the battlefield.”
Weapons being sent include surface-to-air Patriot missile systems and batteries, which Ukrainehas asked for to defend itself from Russian air strikes.

Mr Trump also said he was “very unhappy” with Russia, and threatened “severe tariffs” of “about 100%” if there isn’t a deal to end the war in Ukraine within 50 days.
The White House added that the US would put “secondary sanctions” on countries that buy oil from Russia if an agreement was not reached.
It comes after weeks of frustration from Mr Trump against Vladimir Putin’s refusal to agree to an end to the conflict, with the Russian leader telling the US president he would “not back down”from Moscow’s goals in Ukraine at the start of the month.

Trump says Putin ‘talks nice and then bombs everybody’
During the briefing on Monday, Mr Trump said he had held calls with Mr Putin where he would think “that was a nice phone call,” but then “missiles are launched into Kyiv or some other city, and that happens three or four times”.
“I don’t want to say he’s an assassin, but he’s a tough guy,” he added.
After Mr Trump’s briefing, Russian senator Konstantin Kosachev said on Telegram: “If this is all that Trump had in mind to say about Ukraine today, then all the steam has gone out.”
Meanwhile, Mr Zelenskyy met with US special envoy Keith Kellogg in Kyiv, where they “discussed the path to peace” by “strengthening Ukraine’s air defence, joint production, and procurement of defence weapons in collaboration with Europe”.
He thanked both the envoy for the visit and Mr Trump “for the important signals of support and the positive decisions for both our countries”.
At least 30 people have been killed in the Syrian city of Sweida in clashes between local military groups and tribes, according to Syria’s interior ministry.
Officials say initial figures suggest around 100 people have also been injured in the city, where the Druze faith is one of the major religious groups.
The interior ministry said its forces will directly intervene to resolve the conflict, which the Reuters news agency said involved fighting between Druze gunmen and Bedouin Sunni tribes.
It marks the latest episode of sectarian violence in Syria, where fears among minority groups have increased since Islamist-led rebels toppled President Bashar al Assad in December, installing their own government and security forces.

In March, Sky’s Stuart Ramsay described escalating violence within Syria
The violence reportedly erupted after a wave of kidnappings, including the abduction of a Druze merchant on Friday on the highway linking Damascus to Sweida.
Last April, Sunni militia clashed with armed Druze residents of Jaramana, southeast of Damascus, and fighting later spread to another district near the capital.
But this is the first time the fighting has been reported inside the city of Sweida itself, the provincial capital of the mostly Druze province.
The Syrian Observatory for Human Rights (SOHR) reports the fighting was centred in the Maqwas neighbourhood east of Sweida and villages on the western and northern outskirts of the city.
It adds that Syria’s Ministry of Defence has deployed military convoys to the area.
Western nations, including the US and UK, have been increasingly moving towards normalising relations with Syria.

Concerns among minority groups have intensified following the killing of hundreds of Alawites in March, in apparent retaliation for an earlier attack carried out by Assad loyalists.
That was the deadliest sectarian flare-up in years in Syria, where a 14-year civil war ended with Assad fleeing to Russia after his government was overthrown by rebel forces.
The city of Sweida is in southern Syria, about 24 miles (38km) north of the border with Jordan.
The man convicted of the murder of British student Meredith Kercher has been charged with sexual assault against an ex-girlfriend.
Rudy Guede, 38, was the only person who was definitively convicted of the murder of 21-year-old Ms Kercher in Perugia, Italy, back in 2007.
He will be standing trial again in November after an ex-girlfriend filed a police report in the summer of 2023 accusing Guede of mistreatment, personal injury and sexual violence.
Guede, from the Ivory Coast, was released from prison for the murder of Leeds University student Ms Kercher in 2021, after having served about 13 years of a 16-year sentence.

Since last year – when this investigation was still ongoing – Guede has been under a “special surveillance” regime, Sky News understands, meaning he was banned from having any contact with the woman behind the sexual assault allegations, including via social media, and had to inform police any time he left his city of residence, Viterbo, as ruled by a Rome court.
Guede has been serving a restraining order and fitted with an electronic ankle tag.
The Kercher murder case, in the university city of Perugia, was the subject of international attention.
Ms Kercher, a 21-year-old British exchange student, was found murdered in the flat she shared with her American roommate, Amanda Knox.
The Briton’s throat had been cut and she had been stabbed 47 times.

Ms Knox and her then-boyfriend, Raffaele Sollecito, were placed under suspicion.
Both were initially convicted of murder, but Italy’s highest court overturned their convictions, acquitting them in 2015.
