US President Donald Trump on Saturday (local time) said that Washington will take a decision on Iran, stating that the outcome would come either the "easy way or the hard way", while asserting that Iran has been "decimated".

"We have a decision that I'll make about Iran. Iran's been decimated. So the only question is, it'll either be the easy way or the hard way. We'll have it the easy way or the hard way," Trump said to reporters outside the White House.
