Several non-credible bomb threats that briefly disrupted voting at several Georgia polling places originated from Russia, Georgia Secretary of State Brad Raffensperger told reporters Tuesday.

Five non-credible threats temporarily evacuated two Fulton County, Georgia, precincts for about 30 minutes each,” Fulton County Election Director Nadine Williams said at a morning news conference. “Thankfully, these locations are now operational again and all polling sites are secure with an active security presence,” she said.

Hoax bomb threats, many of which appeared to originate from Russian email domains, were directed on Tuesday at polling locations in five battleground states - Georgia, Michigan, Arizona, Wisconsin and Pennsylvania - as Election Day voting was underway,
