A vessel was struck by an unidentified projectile while crossing the Strait of Hormuz, adding another dangerous episode to the deepening security crisis around one of the world’s most important energy corridors.

The United Kingdom Maritime Trade Operations Centre reported the incident on Sunday after receiving details late Saturday.

According to the British maritime security service, the projectile hit the vessel while it was transiting the narrow waterway between Iran and Oman.

A fire erupted aboard the ship, while local authorities moved to assist with the evacuation of crew members.

UKMTO did not identify the vessel, the projectile, or the party responsible for the attack.

The limited information left shipping companies and energy traders facing another unresolved threat in waters that normally carry a significant share of global petroleum supplies.

The strike came as prospects for renewed direct diplomacy between Washington and Tehran appeared increasingly remote.

Ebrahim Azizi, head of the Iranian parliament’s national security committee, dismissed expectations that negotiations with the United States might restart soon.

“No negotiations. Until Iran’s terms are met, talks are futile,” Azizi said in a post on X. His statement reinforced Tehran’s public refusal to return to discussions without concessions, even as military pressure and commercial disruption continue to mount across the region.

Iran has nevertheless maintained contact with neighboring Gulf governments, including countries affected by Iranian retaliation for United States attacks.

A senior Iranian government official and a Gulf diplomat said Iranian and Gulf representatives were expected to meet in Muscat, Oman, on Monday.

The meeting was expected to produce an agreement establishing an Iran Oman shipping route through the Strait of Hormuz.

The Iranian official stressed that no negotiations with the United States were currently taking place, drawing a firm distinction between regional shipping discussions and broader diplomatic engagement.

Iranian President Masoud Pezeshkian also struck a defiant tone during the BRICS Summit in New Delhi on Friday, declaring that Iran would not surrender under military pressure.

“Iran has successfully stood against Israel and the U.S .,” Pezeshkian said.

“Since we are seeking truth and justice, we will not yield in front of bullying arrogance,” he added.

His comments followed months of escalating attacks involving Iran, Israel, the United States, Gulf infrastructure, commercial vessels, and energy transportation systems.

United States President Donald Trump has defended Washington’s military campaign, arguing that action against Iran prevented a wider assault on Israel, the Middle East, and American cities.

“If I had it to do again, I would do exactly what I did,” Trump said on Thursday.

The Strait has experienced repeated attacks and counterattacks against shipping in recent weeks.

United States Central Command said Wednesday that its forces had destroyed 10 Iranian tankers during the previous week, illustrating the intensity of the maritime confrontation.

CENTCOM said Saturday that United States forces had redirected 100 commercial vessels during the previous 60 days after resuming a naval blockade against Iran.

“ZERO ships have passed through the blockade without U.S. forces allowing,” the command said in a post on X.

Trump suggested Saturday that the war in Iran could end after the November midterm elections, and he predicted that energy costs would decline sharply afterward.

“I think very soon, I think it’ll be right after the midterms, actually,” Trump told reporters during a visit to Ireland.

“I would say shortly, and oil will come tumbling down when that happens.”

The prediction came as crude markets remained highly sensitive to military developments, vessel movements, infrastructure damage, and the limited flow of cargoes through Hormuz.

Oil prices declined Friday but still recorded substantial weekly gains after moving above 100 dollars a barrel for the first time in months.

Brent crude settled 2.8 percent lower at 104.61 dollars a barrel, while West Texas Intermediate fell 2.4 percent to 100.05 dollars.

Brent had climbed to roughly 108 dollars on Thursday, while West Texas Intermediate exceeded 104 dollars.

Those levels reflected mounting concern that continued attacks could further restrict exports from major Gulf producers and leave refiners competing for alternative supplies.

Oil and cargo traffic through the Strait has slowed to a trickle since the United States and Israel began their war against Iran on Feb. 28. Ships and seafarers have been stranded for weeks or months as operators confront blockades, attacks, insurance risks, and uncertain passage approvals.

Saudi Arabia has relied on its East West crude oil pipeline to bypass the Strait, but the kingdom shut the facility Friday as a precaution after several drones launched from Iraq attacked it.

The strikes hit sections of the pipeline in the Riyadh and Medina regions, causing fires, damage, and several injuries.

The vessel strike, pipeline shutdown, and continuing blockade leave the regional energy system under severe strain.

With diplomacy stalled and maritime traffic constrained, every new attack carries immediate consequences for tanker availability, crude pricing, supply planning, and the security of crews operating near Hormuz.
