MOSCOW (AP) Extra security measures are planned for the 2018 World Cup in Russia following hooligan violence at the European Championship, new FIFA secretary general Fatma Samoura said on Tuesday.
Russian fans, some equipped with martial arts gear, clashed with English supporters in Marseille city center and inside the stadium during the tournament in France.
Asked during her first visit to Moscow about fears that such violence could be repeated in Russia, Samoura said ''there will be additional measures,'' including known troublemakers being banned from stadiums.
Samoura said FIFA observers attended all host cities during the European Championship, and their recommendations would form a key part of future security policy.
''All these lessons learned will be used not only here but also in the future by FIFA in any country where we identity a high risk of security,'' she said.
Samoura did not provide specifics of the new measures or say whether any FIFA observers were present for the violence in Marseille.
''Security during the World Cup in the Russian Federation is guaranteed by the government,'' Russian Sports Minister Vitaly Mutko said. ''The security will be unobtrusive, but serious.''
It is not the first time security plans for the 2018 World Cup have been altered. Last year, organizers said there would be a greater focus on securing fan zones from terrorism in the wake of attacks in Paris.
Russia has tightened its anti-hooligan measures in the run-up to the World Cup, introducing legislation to ban offenders from stadiums. An amendment to that law, signed this week by President Vladimir Putin, means blacklisted fans' names will be published by Russian police.
Russian authorities provided just 30 names of suspected troublemakers to French police ahead of Euro 2016, against 2,500 supplied by Germany.
However, Marseille authorities thanked Russian police for sharing intelligence which led to the convictions of three Russian fans for involvement in the Marseille violence and the deportation of 20 more.
Samoura announced the tightened security measures for the World Cup as FIFA revealed the ticket prices for the 2018 tournament.
The cheapest tickets for foreign fans at group stage games will rise more than 16 percent since 2014, with the new prices set at $105 - a $15 increase on the equivalent tickets in Brazil two years ago.
Tickets for the final cost between $455 and $1,100, and those for the opening game between $220 and $550.
Russian residents can benefits from sharp discounts, with the cheapest tickets for the domestic audience selling for 1,280 rubles ($20), roughly the same as those for local fans at the previous tournaments in Brazil and South Africa.
