An “explosive device” has detonated in the Chelsea neighborhood of Manhattan, the New York City fire department confirms. Firefighters and police officers responded to an explosion on Saturday night. At least 25 people are said to have been injured in the blast. 

The fire department was deployed to a building at 135 West 23rd Street near Sixth Avenue around 8.30pm – none of the casualties are thought to be life threatening.

At least three people were seen being taken away on a stretcher from the scene of the blast in ambulances, the area has now been cornered off. There are now fears that there could be a secondary device in the area, as witnesses say the blast was so loud it could be heard from ‘miles away.’

A huge number of police and fire representatives are on the scene, as hundreds of onlookers enjoying a Saturday night out were caught up in the explosion. Authorities told crowds to stay back as it is a ‘dangerous area.’ Police have ruled out that the blast was a gas explosion. They believe that the explosion could be an IED bomb.

Hundreds of people were seen fleeing down the block, as police cordoned off the area. The explosion in the Chelsea neighborhood comes just hours after the deadly pipe bomb that exploded along a route where thousands of runners were due to take part in a charity run in New Jersey.

Two more pipe bombs, that hadn’t exploded, were found in a garbage can near the event which sought to raise money for marines and sailors. The pipe bomb near D Street exploded about 9.30am – the exact time runners were due to pass that location.
