Law enforcement officials are concerned about possible violence by anarchist extremists at the upcoming Republican and Democratic national conventions, according to an intelligence bulletin prepared by the FBI and Department of Homeland Security.
The bulletin, which was obtained by CNN, says that anarchists could try to use improvised explosive devices.
It also says that, as of March, the FBI had intelligence indicating individuals from New York "planned to travel to Tampa and attempt to close" all of the Tampa Bay-area bridges during the Republican National Convention next week.
