Israel's war with Hezbollah looms over planned U.S.-Iran deal signing

Mixed messages about the status of the U.S. naval blockade of Iran's ports and vessels around the Strait of Hormuz, and uncertainty over the terms in the U.S.-Iran agreement, have kept tanker traffic to a minimum so far.

On Sunday, President Trump announced an agreement had been reached with Iran and said in a Truth Social post that he would "authorize the immediate removal of the United States Naval blockade." He later said the strait would only reopen when the deal is signed on Friday, and a multilateral naval command, which includes the U.S., said Monday that the blockade was still in place.

On Tuesday, however, a senior Iranian diplomat said the U.S. blockade had been lifted ahead of the planned signing ceremony, and CBS News has tracked at least four sanctioned Iranian-owned vessels, crossing the U.S. blockade line since Mr. Trump's announcement on Sunday.

Major shipping companies have said they will only resume normal operations in the strait when details of the U.S.-Iran deal are clear, and they get assurances of safety in the vital shipping lanes.

"Due to lack of details and a history of overly optimistic reassurances, we believe the security situation for the shipping industry remains volatile, and we still consider it very risky for ships to commence transits at this point," Jakob Larsen, head of safety and security at BIMCO, one of the largest international shipping associations, said Monday.

Israeli forces carried out airstrikes on several areas in south Lebanon Wednesday, Lebanon's National News Agency reported, despite a memorandum of understanding on the Middle East war that Iran insists includes Lebanon.

NNA said Israeli warplanes launched raids targeting the Nabatieh al-Fawqa area and the eastern outskirts of neighboring town Kfar Tebnit. The Israelis also launched a drone strike on the town of Ansariyeh in the Zahrani area, NNA reported.

Iran's Foreign Minister Abbas Araghchi said Tuesday that the continuing presence of Israeli forces in Lebanon would be a violation of the U.S.-Iran agreement set to be signed on Friday.

On Monday, Israeli officials said troops would remain in a wide section of southern Lebanon that they have effectively occupied over the last three and a half months, forcing tens of thousands of residents to evacuate. 

"Trump's agreement does not bind us," Israel's far-right National Security Minister Itamar Ben-Gvir said.

The first tankers carrying Iranian oil exited a U.S. blockade in the Strait of Hormuz, a tracking website said on Wednesday, two days before Washington and Tehran launch talks under terms of a memorandum of understanding between the two nations.

The negotiations on a final settlement are set to begin Friday at Switzerland's Burgenstock mountain resort after the memorandum is formally signed.

The TankerTrackers website, which monitors oil shipments and storage, marked Iran's "first crude oil exports in two months," citing digital tracking data corroborated by satellite imagery.

"At least two National Iranian Tanker Company (NITC) VLCC supertankers named DIONA (9569695) and HERO2 (9362073) have exited the U.S. Navy blockade perimeter carrying a combined total of 3.8 million barrels of Iranian crude oil between them," TankerTrackers said on X, later adding that a third tanker had exited.

The U.S. will let Iran immediately begin selling oil and fuel under the deal, the Wall Street Journal reported Tuesday, citing unnamed people familiar with the agreement.

The waiver of sanctions on oil sales will take effect immediately after the signing, the Journal said.

Republican Sen. Lindsey Graham of South Carolina told CBS News he's "pretty skeptical" about planned U.S.-Iran talks, but is willing to "wait and see."

The two countries agreed to a memorandum of understanding to extend their ceasefire, reopen the Strait of Hormuz and launch longer-term nuclear talks over the next 60 days.

Asked if he believes that initial deal is a good or a bad idea, the GOP lawmaker and longtime Iran hawk said: "I don't know yet."

"I mean, I like the idea of opening the straits and ending the conflict," he said. "In terms of how the negotiations work long term … let's wait and see. I reserve judgment, but I don't mind jumpstarting the process."

Graham added: "When it comes to Iran, I'm pretty skeptical, but you never know till you try, so it's worth a try."

Graham spoke to reporters after he and other GOP lawmakers met with Defense Secretary Pete Hegseth to discuss Iran and the Pentagon's request for additional funding.
