A teenager who stabbed three young girls to death at a Taylor Swift-themed dance class in England has been sentenced to more than 50 years in prison.

London — A British teen pleaded guilty Monday to murdering three girls and attempting to kill 10 other people in a stabbing rampage at a Taylor Swift-themed dance class in England last summer. Axel Rudakubana, 18, entered the surprise plea at the start of his trial at Liverpool Crown Court.

The British government said Friday it has no plans to change a law barring young people from being imprisoned for life, despite widespread demands for the teenage killer of three young girls to die behind bars.
