The fresh violence threatened to scuttle what U.S. Vice President JD Vance called a “fragile” deal.
The Iranian parliament speaker said planned talks were “unreasonable” because Washington broke three of Tehran’s 10 conditions for an end to the fighting. In a social media post, Mohammad Bagher Qalibaf objected to Israeli attacks on Hezbollah, an alleged drone incursion into Iranian airspace after the ceasefire took effect and U.S. refusal to accept any Iranian enrichment capabilities in a final agreement.
Lebanon’s health ministry said Israeli strikes killed 182 people on Wednesday, the highest single-day death toll in the Israel-Hezbollah war.
White House press secretary Karoline Leavitt said the closing of the Strait of Hormuz, reported in Iranian state media, was “completely unacceptable.” She repeated Trump’s “expectation and demand” that the channel be reopened.
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.”
Only 11 vessels moved through the strait Wednesday, roughly the same as in prior days, according to Windward, a maritime intelligence firm. Iran was requiring shippers to pay tolls of up to $1 a barrel for outbound oil, it said. The largest supertankers carry up to 3 million barrels of crude.
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.
Trump initially said Iran proposed a “workable” plan that could help end the war that the U.S. and Israel launched on Feb. 28. But when a version in Farsi emerged indicating Iran would be allowed to continue enriching uranium — key to building a nuclear weapon — Trump called it fraudulent.
Leavitt said a plan that Iran presented Tuesday could “align with our own” proposal for peace.
The White House said Vance would lead American negotiators at upcoming peace talks, which could begin in Pakistan as soon as Friday.
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.
Arab League chief Ahmed Aboul Gheit accused Israel of “persistently seeking to sabotage” the 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.
Early on Thursday Hezbollah said it had fired rockets at northern Israel and would continue doing so “until the Israeli-American aggression against our country and our people ceases.”
That would upend decades of precedent treating the strait as an international waterway that was free to transit. Such a shift would likely be unacceptable to the Gulf Arab states, which also need to rebuild after repeated Iranian attacks targeting their oil fields.
Trump said the U.S. would work with Iran to “dig up and remove” enriched uranium. 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 Iran refuses to surrender its enriched uranium voluntarily.
Netanyahu warned in a televised address that Israel was “ready to return to fighting at any time. Our finger is on the trigger.”
Tehran has insisted for years that its nuclear program was peaceful, although it has enriched uranium up to 60% purity, a short, technical step from weapons-grade levels.
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. A short time later, the UAE’s air defenses fired at an incoming Iranian missile barrage.
More than 1,900 people had been killed in Iran as of late March, but the government has not updated the toll for days.
