Iran have now said they will not allow ships through.
At around 3pm our time, Hesketh gave a news conference.
This BBC report on the news feed shows just how little the US really knows what its doing - nor its working within the law
"Hegseth was triumphalist in his news conference but in the room few details were forthcoming about the nature of the truce and planned negotiations with Iran.
His statements were marked by contradiction and a lack of clarity.
The administration says the aim of the war was to deny Iran a nuclear weapon in the future. Hegseth said at one point Iran would hand over its stockpile of nuclear fuel “right now”. He didn’t say who would do this, how it would happen, or how it would be verified.
He was later asked about this and said: “They will either give it to us, which the president laid out, or if we have to do something else ourselves."
On the Strait of Hormuz, Tehran has said its re-opening it during the truce will be under Iranian military coordination. Hegseth was asked about control of the strait, and said the oil tankers “will be sailing” but the US retained options.
And he was asked about Trump’s post on Tuesday threatening a “whole civilization” would die, and his threat to destroy all of Iran’s power plants and bridges.
Hegseth quoted the president saying the US could “take it all” including Iran’s “ability to export energy”, adding: “The United States military has the ability to strike those things with impunity”.
This is not true, Congress has a series of laws limiting US conduct in war and has ratified treaties including the Geneva Conventions, which mean its military and leadership cannot act with impunity
