NEW YORK -- A explosion in the Chelsea neighborhood of New York on Saturday night injured at least 29 people, one of them seriously.
Gas has been ruled out as the cause of the explosion, a law enforcement source said. Officials are still trying to assess what caused explosion the source said. Mayor Bill deBlasio said early indications lead them to believe it was intentionally set, but there was no immediate connection to terrorism.
The preliminary belief of investigators is that the explosion was caused by an explosive device in or near a dumpster, a law enforcement source told CNN. The source stressed this is preliminary and is not conclusive.
Some social media users said the sound of the explosion was heard as far away as Hoboken, New Jersey, across the Hudson River from Chelsea.
The fire department said the explosion happened at 23rd Street and 6th Avenue in Manhattan.
