Iran live updates: US strikes Iranian radar sites after drones fired toward strait, CENTCOM says

The U.S. has announced more sanctions targeting Iranian oil smuggling in an effort to undercut Iran's efforts to evade sanctions.

"The United States is targeting a sophisticated network that has smuggled hundreds of millions of dollars' worth of Iranian liquified petroleum gas (LPG) to markets in South and East Asia. This network used front companies in the United Arab Emirates and China, along with Iran's shadow fleet of vessels, to disguise Iranian-origin fuel and circumvent U.S. sanctions," the U.S. said in a statement.

"We are also sanctioning an Iranian currency exchange house and its operators who work with other actors to help Iran facilitate billions of dollars in illicit financial transactions. These dealings enable the regime to move funds derived from oil sales while evading the international financial system," the U.S. added.

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."
