Pressure cookers packed with explosives and detonated with timing devices were used by two Massachusetts brothers in the 2013 Boston Marathon bombing that killed three people and wounded more than 260.The latest blast came less than a week after law enforcement agencies around the country were on heightened alert for the 15th anniversary of the Sept. 11, 2001, airline-hijacking attacks that killed nearly 3,000 Americans in New York, Washington and Pennsylvania. Remaining circumspect about the exact nature of the explosion in Chelsea, De Blasio said early indications were that it was "an intentional act." He added that the site of the blast, outside on a major thoroughfare in the fashionable lower West Side Manhattan neighborhood, was being treated as a crime scene.This is the device found at second location, near New York explosion, officials say. https://t.co/cpgJgDr4X5 pic.twitter.com/TZr07KwDra

"There is no evidence at this point of a terror connection," the mayor said at a news conference about three hours after the blast. "There is no specific and credible threat against New York City at this point in time from any terror organization."The mayor also said investigators did not believe there was any link to a pipe bomb that exploded earlier on Saturday in the New Jersey beach town of Seaside Park. No injuries were reported in that blast, from a device planted in a plastic trash can along the route of a charity foot race. But a US official said that a Joint Terrorism Task Force, an interagency group of federal, state and local officials, was called to investigate the Chelsea blast, suggesting authorities have not ruled out the possibility of a terror connection.A joint task force also took the lead in investigating the New Jersey incident.Manhattan: West 23 St & 7th Ave, moment of the explosion that went off on Street.
