Mayor de Blasio, asked by a reporter whether the blast was terror-related, said, “At this moment, we do not see a link to terrorism.” He added, “There was also no specific evidence of a connection” to the pipe bomb that detonated earlier in the day in New Jersey.

De Blasio stated, ” New Yorkers will not be intimidated. We’re not going to let anybody change who we are and how we go about our lives.”

According to the NYPD, the “investigation is active and extensive.”
