"I don't know anything about harassment cases at the World Cup, there are no problems. We urge everyone to respect each other, this is our main message. But it is clear that appropriate penalties will be imposed for violations of the law," Sorokin told journalists.

The Russia 2018 CEO also said that all the personal data of the FAN IDs holders was being processed in accordance with the memorandum signed by FIFA and the Russian Communications Ministry.

"The data obtained during the issuance of FAN IDs is processed by the Communications Ministry. All actions are based on the memorandum signed with FIFA. It explains clearly what will be done with the data after the tournament," Sorokin noted.

The 2018 FIFA World Cup kicked off on June 14 and will continue until July 15, with the matches being played in 11 cities across Russia. The knockout stage of the tournament will start on Sunday.
