Polling places hit by 'Russian' bomb threats

The FBI says fake 'Russian bomb threats' have been made to polling places in several states as Americans cast their ballots in one of the closest elections in U.S. history.

Polling places in swing states of Georgia, Michigan and Wisconsin were targeted in the plot by the Russians.

But none of the threats have been 'determined to be credible thus far,' the FBI said in a statement on Election Day.
