Axel Rudakubana, 18, pleaded guilty to murder and attempted murder after attacking children and two adults at a dance class last July.

LONDON (Reuters) - 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.

Axel Rudakubana was expected to be sentenced to life in prison at Liverpool Crown Court for the murders of three young girls and attempted murders of eight other children in Southport in July.

Rudakubana, who was 17 at the time of the attack, entered an unexpected guilty plea for the murders of three children at a Taylor Swift-themed dance class.
