Hello and welcome to our live coverage of events in the Middle East.

Donald Trump has ordered the US military to “shoot and kill” small Iranian boats that deploy mines in the strait of Hormuz and claimed that US minesweepers “are clearing the strait right now” amid the standoff over the key waterway.

Trump made the boats announcement in a social media post on Thursday after US special forces boarded a stateless oil tanker in the Indian Ocean which the Pentagon claimed was carrying Iranian crude oil, ratcheting up the standoff with Tehran over the Hormuz strait.

The US president also announced that a ceasefire between Israel and Lebanon would be extended by three weeks.

Trump, speaking to reporters in the Oval Office alongside the participants in the meeting, said he hoped the two countries’ leaders would meet during the additional three-week cessation of hostilities.

The Lebanese ambassador to the US, Nada Moawad, who went into the meeting seeking an extension of the truce, thanked Trump for hosting the talks, saing: “I think with your help, with your support, we can make Lebanon great again.”

In other developments:

Trump said the US had “hit about 75% of our targets” in Iran and that a deal had not yet been reached because Iran was “in turmoil”. Trump added to reporters in the Oval Office that he would not use a nuclear weapon against Iran as the conflict continues without a clear end in sight.

Trump also said the US had “total control over the strait of Hormuz” – a claim that has drawn scepticism in the face of Iran’s seizure of two container ships and a US report warning it could take six months to clear the strait of mines.

Israel’s killing of a Lebanese journalist in a strike has been met with international outrage as Lebanon’s prime minister described the attack as a “war crime”. Amal Khalil, 43, was killed in what colleagues described as a sustained attack by Israeli forces, with rescuers attempting to dig her out of the rubble of a building also targeted and prevented from providing life-saving assistance.
