NEW YORK (WCMH) – New York Gov. Andrew Cuomo called the explosion in the Manhattan neighborhood of Chelsea an “act of terrorism” during a news conference Sunday morning.

“A bomb exploding in New York is obviously an act of terrorism,” Cuomo said.

The blast injured 29 people, but no fatalities were reported. A couple hours after the blast, New York police found a “possible secondary device” a few blocks away. The second device was described as a pressure cooker with items attached and that it was “similar in design” to the one that deontated in a Chelsea dumpster.

Saturday night, Mayor Bill de Blasio said that the blast had not been linked to terror, but Cuomo made a clarification that the incident was not linked to any international terrorist organizations, NBC News reports.
