The US government has warned its citizens of potential terror attacks during the ongoing FIFA World Cup in Russia, in a travel advisory asking people to reconsider visiting the country.

"Large-scale international events such as the World Cup present an attractive target for terrorists," the State Department stated in the advisory. "Although security for the World Cup will be extensive, terrorists may seek to attack event locations such as stadiums and Fan Fest viewing areas, tourist sites, transportation hubs and other public venues," it added.
