Explosion rocks Manhattan 25 injured
The blast at 23rd Street and Sixth Avenue in Chelsea around 8.30pm is thought to have come from a dumpster and could have come from an explosive device.
The Fire Department reported that there were at least 25 people injured in the blast, but their injuries don't appear life-threatening.
The NYPD Special Ops tweeted that they are investigating a 'possible' second device that was found at 27th Street and Sixth Avenue, which is just four blocks away from where the blast occurred.
It comes just hours after a pipe bomb in a trashcan blew up near a fun-run for the military in New Jersey - but no one was injured.
The victims of the explosion have been taken to several different hospitals.
The FBI and NYPD Counterterrorism Unit are investigating but there is no confirmation on what caused the blast yet.
Witness Chris Duffy tweeted a photo of a destroyed dumpster and said it was the source of the blast.
'I was eating at the restaurant Mira with my family and we heard a huge noise and the entire restaurant shook,' Emily Brookstein, 30, of New York told Daily Mail Online.
'My dad thought it was a thunder but we obviously realized later that wasn't the case. We came out of the restaurant and could see smoke. Some say it was a subway bomb, but it was definitely an explosion.'
The NYPD has taken precautions by increasing security across the city following the blast Saturday night.
