The FBI says many of the hoax bomb threats that forced metro Atlanta polling places to temporarily shut down appeared to originate from Russian email domains.

Voting was briefly interrupted in Georgia and several other states Tuesday after law enforcement say bomb threats that appeared to originate from Russia were sent to polling stations. The threats were also sent to polling places in Michigan, Arizona and Wisconsin, officials said.

And the FBI warned that faked video clips were circulating on the internet telling Americans to “vote remotely” because of a terrorist threat.
