" A 20-mile stretch of "Alligator Alley," south Florida's primary cross-state connector, has been closed Friday while bomb squad investigators search two cars and authorities detain three suspects who authorities believe may have been plotting a terror attack in Miami. Florida law enforcement authorities issued an alert Thursday night after receiving a report that a woman in a Calhoun, Georgia, restaurant overheard three men discussing explosives and saying that Americans would "cry on 9/13," a law enforcement official told CNN. The men left the restaurant in two vehicles and headed south on I-75. " |
