USA TODAY , WFAA - NEW YORK - An explosion that injured at least 29 people rocked New York's Chelsea neighborhood Saturday night.
None of the injuries appeared to be life-threatening, the New York City Fire Department said.
The explosion came just after 8:30 pm at 133 West 23rd Street, between Sixth and Seventh Avenues, the Fire Department said.
Twenty four people were transported to area hospitals, officials said.
The cause of the blast remains unknown.
The explosion was in a dumpster outside a 14-story residence for the blind, the New York Post reported. The explosion blew out lower windows on the Associated Blind Housing facility.
New York City Mayor Bill de Blasio and officials spoke during a press conference held late Saturday evening. De Blasio said the New York City Police Department is working two scenes and the area around the explosion is being treated as a crime scene.
The mayor also asked for witnesses or anyone with information on the explosion to contact the NYPD at 1-800-577-TIPS.
The New York Police Counter-Terrorism unit also responded to the blast. Transit service in the area has been shut down, according to the New York Fire Department.
Tweets from the area describe "one loud long boom."
Earlier in the day a pipe bomb exploded in Seaside Park, New Jersey near a Marine charity run. The device was placed in a garbage can. No injuries were reported.
