Iran live updates: Trump details risky, rejected plan to collect 'nuclear dust'

The IDF says that Abed Harb, the commander of Hezbollah’s engineering unit, who was responsible for "assembling explosives intended to harm IDF soldiers in southern Lebanon" has been killed.

The IDF did not offer any further details on how or when he was killed but confirmed the death in a social media post on X early Friday morning.

"He was a senior commander within Hezbollah & was responsible for numerous attacks against IDF soldiers," the IDF said.

Speaking to reporters from the Oval Office on Thursday, President Donald Trump, for the first time, detailed a risky plan that he opted not to greenlight that would have sent U.S. troops into Iran to collect enriched uranium, or "nuclear dust" as he calls it.

The president said he decided not to go forward with the plan given the dangers.

Trump said the operation would have taken at least two weeks and also talked about the "massive equipment" that would need to be airlifted in.

The president added that the U.S. could still carry out such an operation, but also said that there's "no reason to" because the nuclear material is "entombed."

"We could get it right now," Trump said. "I don't think they could stop us if we wanted, but there's no reason to. It's entombed."

When asked what his red line for restarting military action with the war with Iran and whether that line for him is the killing of American troops, President Donald Trump said that such an action would be a "very good reason" to restart the war.

Trump also said he would be open to meeting Iranian Supreme Leader Ayatollah Mojtaba Khamenei, claiming that some have suggested such a meeting.

"I don't want to meet. But if I did meet, I'd be honored to meet him," Trump said. "I'd like to see if we make a deal. But if we make a deal, it's possible that I would meet him. I'd be OK with that."

Israel's Foreign Ministry responded to Hezbollah's rebuke of the ceasefire between Israel and Lebanon, saying that Hezbollah needs to be disarmed.

"Hezbollah leader Na'im Qassem's rejection of the ceasefire and rocket interceptions over Kiryat Shmona tell the story: Hezbollah continues to attack Israel and destabilize the region. The Iranian proxy Hezbollah must be disarmed and its terrorist infrastructure in southern Lebanon must be dismantled according to UN Security Council Resolution 1701," the ministry said in a statement Thursday.
