US President Donald Trump has reiterated his threat of strikes on Iran unless an agreement is reached.

“When I decided that I have to do this for the good of the world, not just for the United States, we were in a lot less trouble than other place,” Trump says, suggesting that the Middle East would have been “taken over” by Iran.

He adds that if Iran is unable to reach a deal, “they won’t be successful. It’ll go very quickly and methodically,” he adds.
