The attack on children at a Taylor Swift-themed summer holiday dance class has been used by far-right activists to stoke anger at immigrants and Muslims.

LONDON (AP) — British Prime Minister Keir Starmer condemned the “tiny mindless minority” behind unrest that has plagued several cities after a horrific stabbing at a children’s dance class and vowed to put a stop to it as the 17-year-old suspect was named Thursday in part to counter misinformation blamed as one cause of the fiery clashes.

Starmer said the recent violence was “clearly driven by far-right hatred” as he announced a program enabling police to better share intelligence across agencies and move quickly to make arrests to prevent the kind of outbursts that have sent scores of police to the hospital the past two nights.

“This is coordinated; this is deliberate,” he said. “This is not a protest that has got out of hand. It is a group of individuals who are absolutely bent on violence.”
