ISIS threatens to attack New York City in new video showing suicide bombers walking into Times Square

ISIS has threatened to bomb New York City in a newly released video, just days after vowing to attack Washington, D.C. The video clip features shots of yellow taxis and crowds in Times Square and Herald Square in Manhattan, with vibrant French music playing in the background - a nod to the Paris terror attacks on Friday.

It then cuts to a man wrapping a bomb around his waist before walking into the crowds and pulling the trigger.

New York police have issued a statement to say they are aware of the footage.They added that there is no direct threat to the city but insist there is a 'heightened state of vigilance'.

'In addition, we are continuing to deploy additional Critical Response Command (CRC) teams throughout the City, out of an abundance of caution,' Stephen Davis, a Deputy NYPD Commissioner, said in a statement on Wednesday.

He added: 'While some of the video footage is not new, the video reaffirms the message that New York City remains a top terrorist target.'

The video, which runs for nearly six minutes, includes a scene that appears to show a suicide bomber making preparations and zipping up a leather jacket.

The clip shows a brief glimpse of Times Square and then of a suicide bomber holding what appears to be a trigger, it said.
