The United States demanded Wednesday that Iran immediately reopen the Strait of Hormuz after the Islamic Republic closed the waterway in response to Israeli attacks against the Hezbollah terror group in Lebanon. Iran’s move cast doubt over whether an already precarious ceasefire to end more than a month of war would hold.

The United States and Iran both claimed victory after reaching the agreement, and world leaders expressed relief, even as more drones and missiles hit Iran and Gulf Arab countries. Israel also intensified its attacks in Lebanon, hitting several commercial and residential areas in Beirut without warning.

The IDF said that it carried out its largest series of airstrikes against Hezbollah since the start of Operation Roaring Lion, targeting hundreds of terrorists in Beirut, the Beqaa Valley, and southern Lebanon. The operation, dubbed by the IDF as “Eternal Darkness,” was carried out by 50 fighter jets that dropped 160 bombs on 100 targets in 10 minutes.

“Aggression towards Lebanon is aggression towards Iran,” Gen. Seyed Majid Mousavi, aerospace commander of Iran’s Revolutionary Guard, wrote on X. He warned that Iranian forces were preparing a “heavy response” without revealing details.

Iranian Foreign Minister Abbas Araghchi insisted that an end to the war in Lebanon was part of the ceasefire agreement with the U.S.

“The world sees the massacres in Lebanon,” he said in a post on X. “The ball is in the U.S. court, and the world is watching whether it will act on its commitments.”

U.S. Defense Secretary Pete Hegseth said American and Israeli forces had achieved a “capital V military victory” and that the Iranian military no longer posed a significant threat to U.S. forces or the region. The Iranian military said the country forced Israel and the U.S. to accept its “proposed conditions and surrender.”

Much about the agreement was unclear as the sides presented vastly different visions of the terms.

— Iran said the deal would allow it to formalize its new practice of charging ships passing through the strait, a crucial transit lane for oil. But the details were not clear, nor was it known whether vessels would feel safe using the channel or whether ship traffic had resumed. It also was unclear whether any other country agreed to this condition. The White House said Trump is opposed to tolls for ship passage through the strait.

— Pakistan, which helped to mediate the deal, and others said fighting would pause in Lebanon, where Israel has launched a ground invasion against the Iran-backed Hezbollah militant group. Israel said it would not, and strikes hit Beirut on Wednesday.

— The fate of Iran’s missile and nuclear programs — the elimination of which were major objectives for the U.S. and Israel in going to war — also remained unclear. Trump said the U.S. would work with Iran to remove buried enriched uranium, though Iran did not confirm that.

In the streets of Tehran, pro-government demonstrators screamed: “Death to America, death to Israel, death to compromisers!” after the ceasefire announcement and burned American and Israeli flags.

The chants underscored the anger animating hard-liners, who have been preparing for what many assumed would be an apocalyptic battle with the United States. Trump warned Tuesday that “a whole civilization will die tonight,” if a deal was not reached.

Ceasefire terms are murky

Trump initially said Iran proposed a “workable” 10-point plan that could help end the war the U.S. and Israel launched on Feb. 28. But when a version in Farsi emerged that indicated Iran would be allowed to continue enriching uranium — which is key to building a nuclear weapon — Trump called it fraudulent without elaborating.

Vance later said the deal was being misrepresented within Iran, though he did not offer details. The White House said Vance would lead the American negotiating team in talks in Pakistan aimed at finding a permanent end to the war.

Iran’s demands for ending the war include a withdrawal of U.S. combat forces from the region, the lifting of sanctions and the release of its frozen assets.

United Nations Secretary General Antonio Guterres’s personal envoy arrived in Iran for talks on “the way forward.”

Pakistan said talks to seek a permanent end to the war could begin in Islamabad as soon as Friday.

Israel backed the U.S. ceasefire with Iran, but Prime Minister Benjamin Netanyahu said the deal does not cover fighting against Hezbollah. Trump told the “PBS News Hour” that Lebanon was not included in the ceasefire deal “because of Hezbollah.”

Israeli Chief of Staff Lt. Gen. Eyal Zamir said Israel will continue to “utilize every operational opportunity” to strike Hezbollah. The Israeli military said it struck more than 100 targets within 10 minutes Wednesday across Lebanon, the largest wave of strikes since March 1.

Lebanese President Joseph Aoun condemned the Israeli attacks as “barbaric.” Arab League chief Ahmed Aboul Gheit accused Israel of “persistently seeking to sabotage” the Iran ceasefire deal.

Hezbollah has not confirmed if it will abide by the ceasefire, though the group has said it was open to giving mediators a chance to secure an agreement. An official, speaking on condition of anonymity because he was not authorized to comment publicly, said the group would not stop firing at Israel unless Israel agreed to do the same.

Iran and Oman will collect shipping fees in Strait of Hormuz

While Iran could not match the sophistication of U.S. and Israeli weaponry or their dominance in the air, its ability to control the Strait of Hormuz proved a tremendous strategic advantage. Iranian attacks and threats deterred many commercial ships from passing through the waterway, through which 20% of all traded oil and natural gas passes in peacetime.

That roiled the world economy and raised the pressure on Trump both at home and abroad to find a way out of the standoff.

The ceasefire may formalize a system of charging fees in the strait that Iran instituted — and give it a new source of revenue.

The plan allows for both Iran and Oman to charge ships, according to a regional official who spoke on condition of anonymity to discuss negotiations they were directly involved in. The official said Iran would use the money it raised for reconstruction.

That would upend decades of precedent treating the strait as an international waterway that was free to transit and will likely not be acceptable to the Gulf Arab states, which also need to rebuild after repeated Iranian attacks targeting their oil fields.

Iranian Foreign Minister Abbas Araghchi said passage through the strait would be allowed under Iranian military management, further clouding the picture of who would be allowed to transit the waterway.

News of the ceasefire sent stock markets surging worldwide, and oil prices plunged back toward $90 per barrel.

Iran’s nuclear and missile threats survive

U.S.-Israeli strikes have battered Iran and its leadership, but they have not entirely eliminated the threats posed by Tehran’s nuclear program, its ballistic missiles or its support for regional proxies, like Hezbollah. The U.S. and Israel said addressing those threats was a key justification for going to war.

Trump said Wednesday that the U.S. would work with Iran to “dig up and remove” enriched uranium that was buried under joint U.S-Israeli strikes in June. He added that none of the material had been touched since. Any retrieval is expected to be an intensive undertaking.

There was no confirmation from Iran.

Hegseth told a Pentagon briefing Wednesday that the U.S. would do “something like” last June’s joint strikes with Israel on Iranian nuclear sites if the country refuses to surrender its enriched uranium voluntarily.

Tehran insisted for years that its nuclear program was peaceful, although it enriched uranium up to 60% purity, a short, technical step from weapons-grade levels.

Iran referred to its nuclear program differently in two versions of the ceasefire plan that it released. The version in Farsi included the phrase “acceptance of enrichment” for its nuclear program. That phrase was missing in English versions shared by Iranian diplomats with journalists.

Airstrikes reported after ceasefire announcement

Shortly after the ceasefire announcement, Bahrain, Israel, Kuwait, Saudi Arabia and the United Arab Emirates all issued warnings about incoming missiles from Iran. That fire stopped for a time, then hostilities appeared to restart.

An oil refinery on Iran’s Lavan Island came under attack, according to Iranian state television. The state broadcaster reported that no one was hurt but did not say who launched the attack. The island is home to one of the terminals that Iran uses to export oil and gas.

A short time later, the United Arab Emirates’ air defenses fired at an incoming Iranian missile barrage. Kuwait said on Wednesday that three power and water desalination plants were badly damaged after 28 Iranian drones were launched at the country. Saudi Arabia said it intercepted nine drones.

More than 1,900 people had been killed in Iran as of late March, but the government has not updated the war’s toll for days.

In Lebanon, where Israel is fighting Iran-backed Hezbollah militants, more than 1,500 people have been killed, and 1 million people have been displaced. Eleven Israeli soldiers have died.

In Gulf Arab states and the West Bank, more than two dozen people have died, while 23 have been reported dead in Israel, and 13 U.S. service members have been killed.
