There's a new warning of possible attacks at the Democratic National Convention next week in Boston.
The FBI says the targets could be news media vehicles and the attackers could be a radical domestic group.
In a statement, the agency says there are unconfirmed reports that a domestic group will try to disrupt the convention "by attacking media vehicles with explosives or incendiary devices."
TV stations were warned Thursday. Satellite trucks are already stationed at the FleetCenter, where the convention begins Monday.
