BREAKING: Al Qaeda Planning Terrorist Attacks In U.S. On Monday... Heres Where While the nation is focusing in on the presidential election next week, CBS News has just learned about a potential terror threat for the day before we choose our next president. Sources told CBS News senior investigative producer Pat Milton that U.S. intelligence has alerted joint terrorism task forces of the possibility that al Qaeda is planning attacks in three states for Monday. New York, Texas and Virginia have all been reported as targets, though no specific locations have been mentioned. A U.S. law enforcement source told reporters that the threat is possibly legitimate and concerning. The source also confirmed the threat may be aspirational. There has reportedly been pressure on the terrorist organization and its affiliates AQAP and AQIS to regain relevance with its mission. U.S. authorities are already taking the threat seriously, though its credibility has not been confirmed. While we do not comment on intelligence matters, we will say the counterterrorism and homeland security communities remain vigilant and well-postured to defend against attacks here in the United States, a U.S. intelligence official told CBS News. The FBI and DHS, working with our federal, state and local counterparts, share and assess 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 safetyAs we have long said, in this environment, homegrown violent extremists could strike with little or no notice. Our concern that violent extremists could be inspired to conduct attacks inside the U.S. has not diminished. The official then gave suggestions to the public. The public should expect to continue to observe an increased law enforcement and security presence across communities in public places, they argued. Our law enforcement community also continues to take action against those who attempt to engage in activities that could put Americans at risk. There are more than 100 Joint Terrorism Task Forces at work across the country in partnership with state and local law enforcement to prevent attacks in the homeland. The New York Police Department also weighed in on the threats, confirming it was working with intelligence agencies and the Joint Terrorism Task Force. With Election Day right around the corner, federal law enforcement is planning for multiple worst-case scenarios. Polling places could be the target of lone-wolf attacks. What do you think? Should these threats be taken very seriously?
