WASHINGTON, Oct. 18 (UPI) -- Seven U.S. stadiums scheduled to have NFL games this weekend have been threatened with radiological "dirty bomb" attacks, CNN reported.
The cable news outlet said the U.S. Department of Homeland Security has told the NFL of a threat seen on a Web site that said the devices would be set off Sunday outside stadiums in Atlanta, Cleveland, Houston, Miami, New York, Oakland and Seattle.
Homeland Security officials told CNN there is no credible intelligence to support the threats and said people should go about their business this weekend. They said they informed the NFL and state and local officials out of an abundance of caution.
The Web site posting threatening the attacks said there would be about 100,000 deaths from the explosions and additional death from radiation, CNN said.
