Cellphone video appears to show the moment a man detonated a pipe bomb inside the Port Authority bus terminal subway station Monday morning.

The footage from a Port Authority surveillance camera monitor shows commuters walking through a narrow hall on the way to the A, C and E trains moments before the blast.

“It’s the guy in the hoodie,” one off-camera voice can be heard saying, referring to the suspect as he enters the frame.

Then, an apparent explosion can be seen, knocking down commuters as a ball of smoke rushes down the passageway toward the camera.

As the dust clears, a single body can be seen lying on the floor.
