The FBI and Department of Homeland Security released a bulletin Wednesday warning of possible terror attacks on the one year anniversary of Osama bin Laden's death.
The advisory said there are no specific or credible threats but officials are still concerned that a "lone wolf" terrorist would view an anniversary attack, on May 1st, "as a symbolic victory."
NYPD spokesman Paul Browne told NBC New York Thursday, "There's no known specific threat to the city because of the anniversary but the NYPD continues to maintain a robust counterterrorism posture regardless of anniversaries because of past and repeated interest demonstrated by terrorists in returning here to kill New Yorkers."
And Representative Peter King (R-NY), who heads the House Homeland Security Committee told CBS, "There is chatter or talk among various terrorists, various Al-Qaeda supporters, about avenging the death of bin Laden. Basically with the first anniversary coming up, this is a warning, advisory to all Americans for keeping their eyes and ears out and also I would say to anyone in airlines, rail, anyone at all, to be extra cautious, extra careful.”
The Associated Press uncovered where the "chatter" was coming from:
[Feds are] concerned about violence from al-Qaida's affiliate in Yemen because of increased intelligence chatter in the past six months, The Associated Press has learned.
The Yemen group, known as al-Qaida in the Arabian Peninsula, or AQAP, has been a persistent concern since 2009, when one of its adherents nearly brought down a jetliner over Detroit on Christmas. In the past six months, counterterrorism officials have seen what they consider an increase in intelligence about potential threats from the group, according to an intelligence official speaking on condition of anonymity to discuss sensitive information.
Osama bin Laden was killed during a raid in Pakistan by Navy SEALS on May 1st, 2011. When New Yorkers heard the news, they flooded the streets in celebration. Check out photos from the night below.
