Protests continue to unsettle U.K. over the three deaths and numerous injuries at a horrific stabbing attack on girls attending a dance class in Southport.

The gruesome attack unfolded on Monday, July 29, at a dance class for children in the seaside town. A 17-year-old man entered the studio and stabbed the children with a knife, killing three and injuring many. Witnesses saw some children covered in blood as they ran away from the attack.
