NYC mayor: Blast was an attempted terrorist attack

No credible threats against NYC at this time, mayor says

New York City Mayor Bill de Blasio assured that there are no other threats against the area in the hours after the explosion.

"At this point in time, all we know of is one individual who, thank God, was unsuccessful in his aims," Mayor de Blasio said.

"There are also no credible and specific threats against New York City at this time. But we will give you more information, of course, as the investigation unfolds," Mayor de Blasio said. "The first responders, responded brilliantly. Now the mission of the NYPD is to secure all major transit hubs and major sites in this city. So you’ll see expanded NYPD presence today all over the city."
