A law enforcement official said, that the explosion appears to have originated from a construction toolbox in front of a building. The official spoke on condition of anonymity because the person wasn’t authorized to speak about an ongoing investigation.

The blast occurred about 8:30 p.m on West 23rd street, in front of a residence for the blind, near a major thoroughfare with many restaurants. The Blast blew out the windows of businesses and scattered debris in the area. Officials said no evacuations were necessary.

Police spokesman J. Peter Donald said several people were taken to hospitals with injuries. One of the injured suffered a puncture wound and was considered serious. Officials said the other injuries were minor, described as scrapes and bruises.

The FBI and Homeland Security officials, along with the ATF arson and explosive task force are also at the scene. The White House said President Barack Obama has been apprised of the explosion in New York City and will be updated as additional information becomes available.

A second device was found four blocks away on West 27th Street. According to several local news sources, it was a pressure cooker attached to a mobile phone by tape with protruding wires.

People living on West 27TH Street were instructed to stay away from their windows while the device was investigated. Police, aided by sniffer dogs, combed refuse bins to ensure there were no other devices.

Reacting to the blast, Republican Presidential candidate Donald Trump said:

It is a terrible thing what's going on in our world, what's going on in our country, but we are going to get tough and smart and vigilant and we are going to end it.

The explosion come hours after a pipe bomb went off in Seaside Park, New Jersey, shortly before thousands of runners participated in a charity 5K race to benefit Marines and sailors. The device, which only partially detonated caused no injuries. Authorities are yet to make any connection between the explosion.
