Governor of New York Andrew Cuomo on Sunday said the explosion in the city's Chelsea neighborhood, in which 29 people were injured, had no links with international terrorism. "At this time, there's no evidence of an international terrorism connection with this incident, but it is very early in the investigation, and it's just starting," he said. "A bomb exploding in New York is obviously an act of terrorism, but it's not linked to international terrorism."

Cuomo added that Saturday's blast had caused "significant damage", and they were "lucky that there were no fatalities", CNN reported. The explosive device went off behind a dumpster on 23rd Street in Manhattan's Chelsea locality, shattering windows of nearby cars and buildings. Locals described the explosion as "ear-shattering". Police later found a second explosive device a few blocks away. It appeared to be a pressure cooker with wires and a phone taped to it.

New York City Mayor Bill de Blasio said the explosion was "an intentional act", but there was no "specific and credible threat" against the city from any terror group. Investigators are looking through surveillance videos, but they have not found any clues so far to direct them to a suspect, an official said.
