A FIFA executive says a terrorist threat has been made on the World Cup.
Secretary general Jerome Valcke commented Friday on an online magazine article that said "how beautiful" it would be if a bomb exploded at the U.S.-England game June 12 in the South African city of Rustenburg.
Valcke says World Cup organizers are working at the "highest level of security."
The comments appeared to come from a contributor to a militant online magazine called "Yearners for Paradise," not the usual sites used by al-Qaida and other groups to make threats.
In the article, the author says he is not a spokesman for al-Qaida.
South Africa's police minister says reports of a terrorist threat to the World Cup can't be ignored, but "hold no water."
Nathi Mthethwa released a statement late Friday, after an online magazine wrote about "how beautiful" it would be if a bomb exploded at the U.S.-England match in Rustenburg.
Police minister Mthethwa says: "Recent media reports suggesting such threats exist hold no water." He said every threat was checked: "We simply cannot ignore them."
