The US Department of Defense have released a video of an airstrike on an Islamic State cash depot, with notes sent flying into the air by the destructive blast.

The footage, released overnight, shows a US strike on a building in Mosul, Iraq.

The clip clearly shows two 2,000-pound bombs hit the building and seconds later plumes of cash can be seen flying into the air.

On CNN Gen. Lloyd Austin, head of the U.S. Central Command, said: "It was a good strike. And we estimate that it served to deprive ISIL of millions of dollars. 

"And combined with all of the other strikes that we've done on ISIL's gas and oil production and distribution capabilities and strikes against his economic infrastructure and the various sources of revenue, you can bet that (it) is feeling the strain on his checkbook.

"ISIL needs those funds to pay their fighters, to recruit new fighters and to conduct their various maligned activities," Austin went on to say.

"You know, we said from the outset of this campaign that to defeat ISIL, we're going to have to take away its ability to resource itself."

Islamic State generates its cash from selling oil as well as collecting a tax from local businesses and farmers.
