It was terrifying and disgusting to see the fans attack with racist actions to England's player. And the players too were out of the line hitting and trying to injure the youngsters of "Lions". England was facing Serbia in their home pitch in a  match for Under 21 players and we saw how bad racism can be. Except of that the supporters started to throw bricks to English footballers and try to hurt them with a bad way. It was an incident that UEFA must handle immediately.
