The U.S. State Department has issued a travel warning for Americans expected to travel to South Africa for the World Cup.
"Large-scale public events like the World Cup may present a wide range of attractive targets for terrorists. There is a heightened risk that extremist groups will conduct terrorist acts within South Africa in the near future," the warning stated. "
FIFA , organizers of the World Cup, has said that that it will take the threats seriously, but will not curb or cancel the games.
''We have freedom in the world to celebrate what we want," FIFA Secretary General Jerome Valcke has told reporters.
