U.S. and Iranian forces clashed in the Gulf and the United Arab Emirates came under renewed attack, but President Donald Trump said a ceasefire was still holding despite the flare-up, which dented hopes for a swift diplomatic resolution to the crisis.
The escalation came as Washington awaited Tehran’s response to a U.S. proposal to end the war, which began on February 28 when the U.S. and Israel launched airstrikes on Iran.
Trump said on Thursday three U.S. Navy destroyers were attacked as they moved through the Strait of Hormuz, a conduit for around a fifth of the world’s oil and liquefied natural gas flows that Iran has all but closed since the conflict began.
“Three World Class American Destroyers just transited, very successfully, out of the Strait of Hormuz, under fire. There was no damage done to the three Destroyers, but great damage done to the Iranian attackers,” Trump wrote on Truth Social.
He later told reporters the ceasefire remained in effect and played down the exchange.
“They trifled with us today. We blew them away,” Trump said in Washington.
Iran, however, accused the United States of breaching the ceasefire, an agreement that has been punctuated by intermittent clashes since it was announced on April 7.
Iran’s top joint military command said U.S. forces had targeted an Iranian oil tanker and another ship, and carried out air attacks on civilian areas on Qeshm Island in the Strait of Hormuz and nearby coastal areas. It said Iranian forces responded by attacking U.S. military vessels east of the strait and south of the port of Chabahar.
A spokesperson for Iran’s Khatam al-Anbiya Central Headquarters said the Iranian strikes inflicted “significant damage,” but U.S. Central Command said none of its assets were hit.
Iranian state media later signalled a de-escalation, with Press TV reporting that, after several hours of exchanges, “the situation on Iranian islands and coastal cities by the Strait of Hormuz is back to normal now.”
The confrontation was not confined to the waterway. The United Arab Emirates said its air defences were engaging missile and drone threats from Iran early on Friday, although details were scarce.
Since the war began, Iran has repeatedly targeted the UAE and other Gulf states that host U.S. military bases.
Oil prices rose in early trade in Asia on Friday, with Brent crude futures rising above $100 a barrel after the latest clashes, while stock prices retreated after strong gains this week on hopes for a swift resolution to the conflict.
“Despite ongoing hostilities and still-elevated oil prices, markets are pricing a limited duration,” said Marija Veitmane, head of equity research at State Street Markets.
China, which has remained a major buyer of Iranian oil since the outbreak of the war, on Friday confirmed that an oil products tanker carrying Chinese crew was attacked near the strait on Monday.
Twenty oil refineries in the Middle East have been struck, or have made precautionary shut downs amid drone attacks, since the start of the Iran war, taking more than 2.3 million barrels per day of capacity offline by mid-April.
Trump said diplomacy was still on track despite Thursday’s hostilities, telling reporters, “We’re negotiating with the Iranians.”
Before the latest clashes, the U.S. had floated a proposal that would formally end the conflict, but did not address two of its core demands – that Iran suspend its nuclear programme and reopen the strait.
Tehran said it had not yet reached a decision on the plan.
Even so, Trump said Tehran had acknowledged his demand that Iran could never get a nuclear weapon, a prohibition he said was implicit in the U.S. proposal.
“There’s zero chance. And they know that, and they’ve agreed to that. Let’s see if they are willing to sign it,” Trump said.
Asked when any deal might be reached, Trump said, “It might not happen, but it could happen any day. I believe they want to deal more than I do.”
The war has tested Trump’s relationship with his U.S. base of supporters, after he had campaigned against involving the United States in foreign wars and promised to bring down fuel prices.
Average U.S. gasoline prices have climbed more than 40% since late February, rising by about $1.20 a gallon to more than $4, according to American Automobile Association data, as disruption to shipments through the Strait of Hormuz has pushed crude oil prices higher.
Despite the loss of many of Iran’s clerical leaders and commanders in U.S.-Israeli attacks – including Supreme Leader Ayatollah Ali Khamenei – the Islamic Republic has not faced the uprising that Trump had encouraged at the outset of the war.
Iran’s judiciary chief, Gholam-Hossein Mohseni-Eje’i, said on Friday Iran would punish those who “betray the homeland”, voicing support for security forces pursuing and apprehending spies, infiltrators and traitors. “We stand firm against those who break unity,” he was quoted as saying by Iranian media.
Iran has in recent weeks detained hundreds of people on espionage-related charges and executed around a dozen for alleged spying for Israel.
