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.

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.”
‘Mom got justice’
“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.”

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.
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.
The brother of a woman killed alongside her family in a helicopter crash in the Hudson River has said they died “without suffering”, and thrown flowers into the water in their memory.
The helicopter’s pilot, Sean Johnson, was also killed.

Mr Camprubi said the family, from Barcelona, Spain, “left together” and “without suffering” following the sightseeing flight over the city. “As a family, we want to [remember] and honour their happiness and their smile forever,” he added.
One of their children, Mercedes, was due to celebrate her ninth birthday on Friday, the day after the crash. The other children were Victor, who was four, and 10-year-old Agustin.
Mr Camprubi told reporters on Saturday: “We will never forget you. And we will keep your smile alive every day of our lives. And that, I think, is the greatest legacy that we can give.”

New York Mayor Eric Adams joined Mr Camprubi to throw flowers and lamented that “what should have been a joyful vacation turned into an unimaginable tragedy”.
He also paid tribute to Mr Johnson, a former US Navy Seal, but said “no words can fill the void, the loss” that bereaved relatives are enduring.

National Transportation Safety Board (NTSB) investigators have not yet determined the cause of the crash.
There were reports of a loud boom when the aircraft, a Bell 206, broke apart, and officials previously said they were looking into reports of a large flock of birds being seen beforehand.
As divers continued to pull pieces of the wreckage from the Hudson on Saturday, NTSB officials said they were checking the flight control system. The helicopter was not equipped with any black box flight recorders.
Its main rotor, main gear box, tail rotor, and a large portion of the tail boom are still missing, the NTSB said.

Iran says “indirect talks” over the country’s rapidly advancing nuclear programme have taken place with US officials, with more to come next week.
The discussions on Saturday took place in Muscat, Oman, with the host nation’s officials mediating between representatives of Iran and the US, who were seated in separate rooms, according to Esmail Baghaei, a spokesperson for Iran’s foreign ministry.
After the talks concluded, Oman and Iranian officials reported that Iran and the US had had agreed to hold more negotiations next week.
Oman’s foreign minister Sayyid Badr Albusaidi tweeted after the meeting, thanking Iran’s foreign minister Abbas Araghchi and US Middle East envoy Steve Witkoff for joining the negotiations aimed at “global peace, security and stability”.
“We will continue to work together and put further efforts to assist in arriving at this goal,” he added.

Iranian state media claimed the US and Iranian officials “briefly spoke in the presence of the Omani foreign minister” at the end of the talks – a claim Mr Araghchi echoed in a statement on Telegram.
He added the talks took place in a “constructive atmosphere based on mutual respect” and that they would continue next week.

American officials did not immediately acknowledge the reports from Iran.
Mr Araghchi said before the meeting on Saturday there was a “chance for initial understanding on further negotiations if the other party [US] enters the talks with an equal stance”.
He told Iran’s state TV: “Our intention is to reach a fair and honourable agreement – from an equal footing.
“And if the other side has also entered from the same position, God willing, there will be a chance for an initial agreement that can lead to a path of negotiations.”
Reuters news agency said an Omani source told it the talks were focused on de-escalating regional tensions, prisoner exchanges and limited agreements to ease sanctions in exchange for controlling Iran’s nuclear programme.

Trump on Monday: ‘We’re in direct talks with Iran’
President Donald Trump has insisted Tehran cannot get nuclear weapons.
He said on Monday that the talks would be direct, but Tehran officials insisted it would be conducted through an intermediary.
Saturday’s meeting marked the first between the countries since Mr Trump’s second term in the White House began.
During his first term, he withdrew the US from a deal between Iran and world powers designed to curb Iran’s nuclear work in exchange for sanctions relief.
He also reimposed US sanctions.
Iran has since far surpassed that deal’s limits on uranium enrichment.
Tehran insists its nuclear programme is wholly for civilian energy purposes but Western powers accuse it of having a clandestine agenda.
Mr Witkoff came from talks with Russian president Vladimir Putin on Friday, as the US tries to broker an end to the war in Ukraine.
