'Bibi's hair on fire': Trump, Netanyahu had tense phone call on future of Iran war, say reports

United States President Donald Trump and Israeli Prime Minister Benjamin Netanyahu had a tense phone call over the future course of the ongoing war on Iran, US media reported, as Washington appeared to be in favour of a deal instead of the resumption of strikes.

Media outlet Axios reported on Wednesday that, after the Tuesday phone call with Trump, Netanyahu's "hair was on fire".

He further added that he was keen on strikes to be resumed in attempts to target Iran's military capabilities and weaken the regime by destroying its critical infrastructure.

Trump on Sunday informed he had planned to postpone the attack on Iran, planned for Tuesday, acting upon a request from Arab nations including Qatar and the UAE.

Trump continues to say he thinks a deal can be struck, but that he's ready to resume the war if it isn't.

"The only question is, do we go and finish it up, or are they gonna be signing a document. Let's see what happens," the US President said on Wednesday.

Later that day, he said the US and Iran were "right on the borderline" between getting a deal and resuming the war.

"It's right on the borderline, believe me. If we don't get the right answers, it goes very quickly. We're all ready to go. We have to get the right answers - it would have to be a complete 100 per cent good answers," Trump told reporters.

There is a strong desire in the upper echelons of the Israeli government for renewed military action, CNN quoted a source, and mounting frustration that Trump is continuing to allow what they say is Iran's diplomatic foot-dragging.

Trump also added that Netanyahu "will do whatever I want him to do" on Iran, though he also said they had a good relationship.

Iran has confirmed it's reviewing an updated proposal, but has not yet shown any signs of flexibility.

Iran's foreign ministry said Wednesday that talks on negotiations were ongoing "based on Iran's 14-point proposal," and that Pakistan's interior minister was in Tehran to help the mediation.

Trump told Netanyahu that the mediators were working on a "letter of intent" that both the US and Iran would formally sign to conclude the ongoing war and launch a 30-day period of negotiations on issues like Iran's nuclear program and re-opening of the Strait of Hormuz, a US source briefed on the call information told Axios.
