The Iranian military command ‌said the closure was the “first ‌step” in response to what it described as breaches of the ceasefire agreement, warning that further measures would ‌be taken if “aggression” continued, according to state media.

The Islamic Revolutionary Guard Corps warned vessels not to approach the shipping lane, saying their security would be at risk.

The US military denied Iran had control of the strait. A spokesman for Central Command said: “Traffic continues to flow, and US forces are monitoring the situation ‌to ensure this remains the case.”

The reports emerged as JD Vance, the US vice-president, told Fox ​News that ‌he was confident ​the ceasefire agreed in Washington’s 14-point deal ⁠with ⁠Tehran would hold. He claimed there was no evidence that the strait was shut.

Israeli strikes on Lebanon killed 16 people this morning, with the country claiming it was responding to attacks by Hezbollah.

A pause on fighting in Lebanon is a condition for continuing peace negotiations, which will also include discussions on Tehran’s nuclear programme.
