A death row prisoner in Alabama is fighting plans for him to be the first person to be executed using nitrogen gas.
The new execution method of nitrogen hypoxia causes death by forcing the prisoner to breathe only nitrogen, depriving them of oxygen.
Authorities in Alabama want to execute Kenneth Smith using the method – but the inmate’s lawyers say he should not be used as a “test subject”.
Smith’s lawyers argued the state has disclosed little information about how nitrogen executions would work, calling the method “untested”.
Nitrogen hypoxia has been approved for use in three US states, but has not yet been used in an execution.
Nitrogen makes up 78% of the air inhaled by humans and is harmless when inhaled with proper levels of oxygen. During execution, a mask would be fitted over the inmate’s face and their air supply would be replaced with nitrogen until their heart stops.
Supporters of the new method have suggested it would be painless, but opponents have compared it to human experimentation.

Trip Pittman, the former Alabama state senator who proposed the new execution method, has disputed criticism the method is experimental.
He said while no state has carried out a death sentence with nitrogen, people have died by breathing nitrogen during industrial accidents and suicide attempts, so the effects are known.
Smith’s lawyers said he “already has been put through one failed execution attempt” in November when the state tried to put him to death via lethal injection.
The attempt had to be called off when the execution team could not get the two required IV lines attached.
The lawyers said Smith has ongoing appeals and accused the state of trying to move Smith to “the front of the line” ahead of other inmates to get around Smith’s lawsuit challenging lethal injection procedures.
Smith was convicted in the 1988 murder-for-hire killing of Elizabeth Sennett.
Prosecutors said Smith was one of two men who were each paid $1,000 to kill Ms Sennett on behalf of her husband, who was deeply in debt and wanted to collect on insurance.

Thousands of people gathered in various cities across the US as protests against Donald Trump and Elon Musk took place in all 50 states on Saturday.
Around 1,200 demonstrations were planned in locations including Washington DC, New York City and West Palm Beach, Florida – just miles away from where the US president has this weekend played golf.
The “Hands Off!” protests were against the Trump administration’s handling of government downsizing, human rights and the economy, among other issues.
In Washington DC, protesters streamed on the grass in front of the Washington Monument, where one person carried a banner which read: “Make democracy great again.”

Another protester took aim at Mr Trump‘s handling of Russia and Ukraine, with a placard that read: “Stop Putin’s puppets from destroying America.”
Tesla boss Mr Musk also featured on many signs due to his role in controversial government cuts as head of the newly created Department of Government Efficiency (DOGE).

Terry Klein, a retired biomedical scientist, said she drove to the rally to protest Mr Trump’s policies on “everything from immigration to the DOGE stuff to the tariffs this week, to education”.

Some at the various protests carried Ukrainian flags, while others sported rainbow attire and waved rainbow flags in support of the LGBTQ+ community.
Other protesters wore Palestinian keffiyeh scarves and carried “Free Palestine” signs.
Protesters refuse to take Donald Trump’s policies lying down
It was built to honour George Washington, a founding father of the United States.
And in the shadow of the 555ft Washington Monument, protestors were refusing to accept Donald Trump’s policies lying down.
“Stand tall,” they chanted, again and again.
“In every city, stand tall. In every state, stand tall. In truth, stand tall. In justice, stand tall.”
Those words, shouted by thousands on the city’s iconic mall, were reinforced by the words on their placards and t-shirts.
A minister, wearing a t-shirt with ‘Troublesome Priest’ printed on it, told me she found what was happening in the US government “appalling and immortal”.
One man said he had won the long-distance award, having travelled 2,750 miles from Hawaii for the protest.
“I finally reached a breaking point,” he added. “I couldn’t take it anymore.”
Another woman said: “We have to speak up, we have to act, we have to do something, because this is not America.”
I asked her what she would say to those who argue the people did speak when they elected Donald Trump as president.
She replied: “Some people have spoken and then some people have not and those of us that have not, we need to speak now.”
Thousands marched in New York City’s midtown Manhattan and in Boston, Massachusetts, while hundreds gathered in the sunshine outside the Utah State Capitol building in Salt Lake City, and in the rain outside the Statehouse in Columbus, Ohio.

Mr Trump – who shook financial markets with his tariffs announcement this week – spent the day in Florida, playing a round of golf before returning to his Mar-a-Lago residence.

Some four miles from Mar-a-Lago, more than 400 people gathered – and drivers honked their horns in support of protesters who held up signs including one which read: “Markets tank, Trump golfs.”
The White House has said Mr Trump plans to go golfing again on Sunday.
Global financial markets gave a clear vote of no-confidence in President Trump’s economic policy.
The damage it will do is obvious: costs for companies will rise, hitting their earnings.
The consequences will ripple throughout the global economy, with economists now raising their expectations for a recession, not only in the US, but across the world.
