Referees will be given the power to stop and abandon games if they witness any discrimination from fans in this year's Confederations Cup.

"These are ground-breaking changes in the fight against discrimination," said Fifa president Gianni Infantino.

"Both initiatives are extra tools for the referees and match officials to prevent discriminatory attitudes and ensure that the atmosphere in the stadium is one of fair play and respect."
