A violence-obsessed teenager has repeatedly interrupted his sentencing hearing for stabbing three young girls to death at a Taylor Swift-themed summer dance class.

Prime Minister Keir Starmer says "fundamental change" in how the British state protects its citizens is needed.

The mass stabbing in Southport, England, and misinformation about the attacker sparked days of rioting across the U.K.

After Axel Rudakubana was charged with the murder of three girls and the attempted murder of 10 others at a Taylor Swift-themed dance class in England, the now-18-year-old has pleaded guilty.
