US President Donald Trump has told reporters that he is not satisfied with Iran’s latest proposal for resolving the conflict and that negotiations were taking place by phone, Reuters reports.

“In terms of the negotiation, telephonically. They’ve (Iran) made strides, but I’m not sure if they’ll ever get there,” he tells reporters.

“There’s tremendous discord; they’re having a tremendous problem getting along with each other in Iran. The leadership is very disjointed — it’s got two to three groups, maybe four.

“It’s a very disjointed leadership and, with that being said, they all want to make a deal, but they’re all messed up,” Trump adds.
