President Donald Trump has denied a New York Times report that US officials are discussing a military plan to send up to 120,000 troops to the Middle East to counter any attack or nuclear weapons acceleration by Iran.

"I think it's fake news, OK? Now, would I do that? Absolutely. But we have not planned for that. Hopefully we're not going to have to plan for that. And if we did that, we'd send a hell of a lot more troops than that," Trump told reporters at the White House on Tuesday.
