Donald Trump says he 'may or may not' strike Iran as Israel's air war continues

US President Donald Trump says he has yet to decide whether the US will join Israel militarily in its campaign against Iran.

Asked whether the US was getting closer to striking Iran's nuclear facilities, Mr Trump said: "I may do it. I may not do it." Speaking outside the White House on Wednesday, he added: "Nobody knows what I'm going to do...Iran's got a lot of trouble, and they want to negotiate.

"And I said, 'why didn't you negotiate with me before all this death and destruction?'" Mr Trump said Iran had reached out to Washington, a claim Tehran denied, with Iran's mission to the UN responding: "No Iranian official has ever asked to grovel at the gates of the White House." Iran's supreme leader, Ayatollah Ali Khamenei said Iran would not surrender and warned "any US military intervention will undoubtedly cause irreparable damage" to US-Iranian relations.

Strikes continue Hundreds have reportedly died since Iran and Israel began exchanging strikes last Friday, when Israel launched an air assault after saying it had concluded Iran was on the verge of developing a nuclear weapon, a claim Tehran denies.

Israel launched three waves of aerial attacks on Iran in the last 24 hours, military spokesman Brigadier General Effie Defrin has said. Israel deployed dozens of warplanes to strike over 60 targets in Tehran and western Iran, including missile launchers and missile-production sites, he said.

"The aim of the operation is to eliminate the existential threat to the State of Israel, significantly damage Iran's nuclear programme in all its components, and severely impact its missile array," he said. Early on Thursday Israel issued an evacuation warning to residents of the Iranian Arak region where Iran has heavy water reactor facilities.

Heavy water is important in controlling chain reactions in the production of weapons grade plutonium. Meanwhile Iran says it has arrested 18 people it describes as "enemy agents" who it says were building drones for the Israelis in the northern city of Mashhad.

Iran also launched small barrages of missiles at Israel on Wednesday with no reports of casualties. Israel has now eased some restrictions for its civilians.
