FIFA president Gianni Infantino says referees will have the power to abandon matches at the World Cup if there are incidents of racism.
There are fears the tournament in Russia, starting next Thursday, could be dogged by discrimination after historic problems in the country.
England defender Danny Rose has told his family not to travel to avoid being abused, with his manager Gareth Southgate backing the Tottenham player on Wednesday.
Infantino says there are measures in place should anything occur during matches and has warned of “serious consequences” if there are such issues.
He said: “I wouldn’t say that we are concerned about discrimination, human rights and security but we take them very seriously, We have taken appropriate measure in the preparation process.
