"I hope everything will be fine and there will be no [fights]. Special attention is being paid to security issues. People should understand that sport unites. Friendly matches among fans will be organized for this reason. People will play against each other and football is what will unite them," Ishchenko told journalists.

She added that a lot of fans from Serbia and Croatia are expected to come to Kaliningrad during the tournament.

Russia will host the 2018 FIFA World Cup for the first time from June 14 to July 15, with the games set to be held in a total of 11 cities.

The 35,000-seater Kaliningrad Stadium will host four group-stage matches, including a game between England and Belgium on June 28.
