Police investigating a mass stabbing on an English train on Saturday say there is nothing to suggest it was a terrorist attack.
Speaking from outside Huntingdon Station, British Transport Police Superintendent John Loveless said two men being held over the attack were British nationals, and remained in custody.
"At this stage, there is nothing to suggest it was a terrorist incident," he said.
Ten people were taken to Addenbrooke's Hospital in Cambridge following the incident, with nine believed to have suffered life-threatening injuries at the time.
"Four have since been discharged, however two patients remain with life-threatening injuries," Superintendent Loveless said
British Transport Police said the attack had nevertheless been declared a major incident and counterterrorism officers were still supporting the investigation.
Police began receiving emergency calls shortly after the train departed Doncaster for King's Cross Station in London.
Superintendent Loveless said within eight minutes of the first emergency call, two men were taken into custody.
"Passengers will see a high visibility presence of police officers at stations and on trains throughout today up and down the transport network. Our officers are there to reassure the public and to address any concerns they may have," he said.
[Train map]Huntingdon MP Ben Obese-Jecty told the ABC that the incident could have been a lot worse if not for the swift action of railway workers.
"The attack took place shortly after the train left … it wasn't scheduled to stop at Huntingdon, which is the next stop, it was on a fast line to the next stop," he said.
"It's down to the swift action of the railways to be able to get the train onto the slower line so that it was able to stop at Huntingdon, which has multiple lines running through it.
"And it was only because it stopped at Huntington that people were able to get off the train and that the police were able to respond.
"If the train had gone to Stevenage, it would have been another 10 or so minutes of the attacker being on the train with individuals trapped on the train with them."
Britain's defence minister, John Healey, said early indications were that the stabbing was "an isolated attack".
"The early assessment is that this was an isolated incident, an isolated attack," Mr Healey told Sky News on Sunday.
UK Prime Minister Keir Starmer called the attack an "appalling incident" which was "deeply concerning", while Interior Minister Shabana Mahmood said she was "deeply saddened" and urged people to avoid speculating about the incident without basis.
The British government is keen to stop rumours spreading on social media following an incident in Southport, in north-west England, in 2024, when internet claims about the murder of three young girls sparked days of rioting across the country.
