Al-Qaeda may be planning pre-Election Day attacks on Monday in New York, Texas and Virginia.
US intelligence officials have alerted joint terrorism task forces of the threat, whose credibility was still being assessed, sources told The Post.
Specific sites that may be targeted in the three states were not mentioned in the threat, the source said.
“The counterterrorism and homeland security communities remain vigilant and well-postured to defend against attacks here in the United States,” a senior FBI official told CBS News.
“The FBI, working with our federal, state and local counterparts, shares and assesses intelligence on a daily basis and will continue to work closely with law enforcement and intelligence community partners to identify and disrupt any potential threat to public safety,” the official said.
