(NEW YORK) -- Officials may have the name of one of the suspected bomb plotters behind the specific, credible but unconfirmed threat announced Thursday against the U.S.
The 24-hour intelligence manhunt included an analysis of flight logs and other documents following a report from a CIA informant that three people were dispatched by al Qaeda to carry out a bomb plot in the U.S., intending to strike either New York or Washington D.C.
The three men, at least two, could be three American citizens or those with visas, and may have allegedly travelled to the U.S. in mid-August.
New York Gov. Andrew Cuomo ordered additional state troopers to help secure the World Trade Center site, Penn Station, Grand Central Station, bridges and tunnels, and other key infrastructure sites and state facilities.
Homeland Security is adding additional security at airport checkpoints and boosting the number of air marshals aboard flights.
