Iran live updates: 'Suspected' mine reported in Strait of Hormuz, authorities say

U.S. military searches so far have not found any Iranian mines that may have been placed in the Strait of Hormuz, according to a U.S. official.

U.S. intelligence reports have mentioned that Iran has placed mines in the Strait, according to another U.S. official, who said that at one point it was believed that Iran had placed at least a dozen mines in the waterway. Earlier Friday, President Donald Trump also once again referenced in a social media post how Iranian mines have previously been destroyed or removed by the U.S.

But U.S. military searches in the crucial waterway since the start of the war have not found definitive evidence of any mines, according to a U.S. official. Those searches have involved underwater drones and aircraft reconnaissance, according to the U.S. official.

In a statement, a U.S. Central Command spokesperson said: "U.S. military efforts for ensuring the Strait of Hormuz is fully clear of sea mines laid by Iran’s Islamic Revolutionary Guard Corps are ongoing. We are unable to publicly discuss specifics at this time for operational security reasons."

NBC News was first to report that the U.S. has not confirmed that Iran placed mines in the Strait of Hormuz.

After meeting with his team in the Situation Room for about two hours on Friday to make a "final determination" about a deal with Iran, President Donald Trump has yet to announce a decision.

Following the meeting, a White House official said in a statement, "President Trump will only make a deal that is good for America and satisfies his redlines. Iran can never possess a nuclear weapon."

It is not clear why the president still has not announced a decision.

The U.S. Treasury Department has sanctioned the Persian Gulf Strait Authority — the entity created by Iran to manage and charge for passage through Strait of Hormuz.

Prior to this move, the Treasury Department had already warned that providing payment to the PGSA for passage through the strait could open the payer up to sanctions risks, and that firms that facilitate financing could be subject to secondary sanctions. The move to formalize the sanctions is a potential sign the administration could seek to step up enforcement of the penalties.

Secretary of State Marco Rubio and Lebanon’s President Joseph Aoun held a call on Friday, during which Rubio "reiterated that Hizballah is entirely responsible for the ongoing fighting” in the country, according to the U.S. State Department.

The readout makes no mention of the ceasefire agreement between Lebanon and Israel but says Rubio "commended President Aoun’s courage and vision in pursuing direct negotiations with Israel” during their conversation.

Negotiations between Lebanon and Israel are set to resume in Washington next week.
