An alleged terrorist plot to attack a major U.S. target and tank the economy is foiled by an elaborate FBI sting. The suspect is a 21-year-old student, who came to the U.S. on a student visa from Bangladesh.

Investigators say Quazi Nafis parked what he thought was a 1,000 pound explosive device outside the Federal Reserve in New York City. NYPD says this is the 15th terror plot they’ve foiled since 9/11. 

CNN National Security Analyst Peter Bergen discusses the details.
