A British teenager who killed three young girls at a Taylor Swift-themed dance event was jailed for at least 52 years on Thursday, for an attack Prime Minister Keir Starmer called one of the most harrowing moments in Britain's history.

A British teenager on Monday pleaded guilty to charges of murdering three young girls in a knife attack in northern England in July, a crime that horrified the nation and was followed by days of nationwide rioting.

I consider it likely he will never be released,” judge says, adding that Axel Rudakubana must serve a minimum of 52 years in detention for his “extreme violence”.

Axel Rudakubana on Monday admitted committing the deadly attack last July. Officials later said he had been referred to a government counterterrorism program three times before his rampage.

A British teenager on Thursday repeatedly interrupted the start of his sentencing for murdering three young girls at a Taylor Swift-themed dance event last July, shouting from the dock that he was unwell before being removed.
