The 2011 Manhattan terrorism plot was a conspiracy by two Muslim Arab-Americans to bomb various targets in the Manhattan borough of New York City, New York, United States. They had planned to attack an unspecified synagogue and one of them expressed interest in blowing up a church and the Empire State Building. New York City law enforcement arrested the two suspects, 26-year-old Ahmed Ferhani and 20-year-old Mohamed Mamdouh, in a sting operation on May 11, 2011. Their plot was motivated primarily by "hatred of infidels and anti-semitism" according to the authorities.
