At least 29 people suffered non-life threatening injuries in an explosion which occurred in a crowded Chelsea neighbourhood in Manhattan on Saturday night. According to the New York Fire Commissioner, Daniel Nigro, one person was seriously injured.
New York Mayor Bill de Blasio said a second site was being investigated.
“Tonight, New York City experienced a very bad incident,” de Blasio said at a news conference near the scene. “We have no credible and specific threat at this moment”.
De Blasio said the blast was “an intentional act” and tried to calm any fears among nervous New Yorkers, saying the explosion had no terrorist connection and wasn’t related to a pipe bomb explosion earlier Saturday in New Jersey at a charity run.
A law enforcement official said the explosion appears to have originated from a construction toolbox in front of a building. The official spoke on condition of anonymity because the person wasn’t authorised to speak about an ongoing investigation, AP reports.
