Iran live updates: Trump promises more attacks against Iran on Wednesday

President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.

Following the announcement of a two-week ceasefire, initial U.S.-Iran talks in Pakistan in April failed to reach a peace deal.

Trump later announced the open-ended extension of the ceasefire and the continuation of a U.S. blockade until negotiations are concluded "one way or the other."

Iranian President Masoud Pezeshkian says the country will "stand firm" amid threats from the U.S. of more attacks against the country, denouncing threats against Iranian infrastructure.

"Threats to target them – from transportation networks to the electricity and water industries – are not a show of strength but a sign of desperation in the face of a nation’s will,” he said.

Pezeshkian’s post comes after President Donald Trump said his administration would be “attacking [Iran] very hard."

Iran "will stand firm against any pressure or threat," Pezeshkian said.

President Donald Trump alluded to apparent U.S. operations to stimulate shipping through the Strait of Hormuz, with Trump claiming that the U.S. took 22 ships, amounting to millions of barrels of oil, through the strait the other day.

"Do you know we've been taking out millions of barrels of oil? Nobody knows it. You know who doesn't know about it? Iran, until right now," Trump told reporters at the White House on Wednesday.

Trump claimed the U.S. "blasted" Iran's radar, enabling the seizures.

"We took out the other night 22 ships late at night with no lights, because they don't have any radar," Trump said, claiming "that’s why oil’s $85 a barrel."

Earlier Wednesday, Trump said on social media that nothing is getting through the U.S. Naval blockade at the Strait of Hormuz "unless we want it to." He added, "Lots of oil is getting out."

U.S. Central Command said it disabled a vessel, the M/T Settebello tanker, as it transited in the Gulf of Oman on Wednesday.

Three Indian crewmembers have been reported missing after the attack, according to the Indian Ministry of Foreign Affairs.

A U.S. aircraft fired precision munitions at the ship’s engine crew "after the crew repeatedly failed to comply with directions from American forces," CENTCOM said in a statement.

Twenty-one Indian crewmembers of the Settebello were rescued and India is coordinating with Omani authorities regarding the operation, the Indian ministry said.
