The postponement came as Washington and Tehran hardened their positions over what any future negotiations should cover. The Trump administration wants talks with Iran focused on Tehran’s nuclear program rather than reopening the Strait of Hormuz, CNN reported, citing three sources familiar with the matter.
Iran, meanwhile, has signaled that it would consider nuclear negotiations only after the dispute over the strait is resolved, including the lifting of the US naval blockade.
Omani Foreign Minister Badr Albusaidi said the meeting planned for Monday in Salalah had been postponed “in the interests of consensus.” Iran’s IRGC-affiliated Fars News later reported that Tehran and Muscat had jointly agreed to the delay at the request of some regional countries.
Saudi Arabia had submitted amendments to the Omani-Iranian proposal over concerns that its wording could establish a new status quo in the strait unacceptable to Riyadh and other GCC states, Axios reported Sunday, citing a senior regional official.
The disagreements have emerged despite a flurry of regional diplomacy. Qatar’s prime minister and Oman’s foreign minister discussed efforts toward a solution guaranteeing freedom of maritime navigation, while the foreign ministers of Kuwait and Saudi Arabia also discussed ensuring the safety and freedom of shipping through Hormuz.
US blockade remains in force
The United States has continued to tighten its maritime pressure on Iran even as regional states search for a diplomatic arrangement.
US Central Command said Sunday that American forces had redirected 101 commercial vessels to ensure compliance with the blockade against Iran, up from 100 a day earlier.
US officials told CNN they believe American forces currently have the military upper hand in the strait, but questions remain over how long Washington can sustain the large-scale escort and naval operation.
Iranian Foreign Minister Abbas Araghchi has said an agreement with Oman on shipping arrangements would not itself reopen the strait, insisting that reopening depends on Washington meeting Tehran’s demands.
President Donald Trump, meanwhile, said Sunday that Iran “wants to make a deal so badly” and suggested the war could end before or shortly after the US midterm elections.
Vessel strike adds to Hormuz risks
Security risks around the strait also intensified on Sunday after an Iranian commercial container ship was struck by an unidentified projectile near Hengam Island, off Qeshm.
Iranian authorities said one crew member was killed and four others wounded. UK Maritime Trade Operations separately reported a vessel struck by an unknown projectile in the Strait of Hormuz, followed by a fire and crew evacuation, though it was not officially confirmed that the two reports concerned the same vessel.
Several explosions of unknown origin were also reported later Sunday in Sirik, in southern Hormozgan province, according to Iranian state media.
Saudi oil route under pressure
The pressure on Hormuz has become more acute for Saudi Arabia after drone attacks forced it to shut its East-West oil pipeline, a critical route carrying crude from the kingdom’s eastern oilfields to the Red Sea.
The pipeline had been transporting around 4 million barrels per day and allowed Riyadh to bypass the disruption in Hormuz. Reuters reported that stocks at the Red Sea port of Yanbu may be sufficient to sustain exports for only five to seven days if the pipeline remains shut, after which as much as 4% of global oil supply could be at risk.
Oil prices rose sharply as markets reopened, with Brent climbing above $108 a barrel after fresh attacks on Saudi Arabia and shipping in the Persian Gulf.
The Iraqi government has meanwhile stepped up security measures after Saudi Arabia said drones used in the pipeline attack were launched from Iraqi territory. Baghdad has begun reopening several border crossings with Iran after temporary closures and security reviews, with commercial traffic through Shalamcheh expected to resume Monday.
Houthis tighten pressure at Bab el-Mandeb
Saudi Arabia is also facing growing pressure on its western flank as Yemen’s Iran-aligned Houthis expand their position around Bab el-Mandeb, the narrow waterway linking the Red Sea to the Gulf of Aden.
The Houthi advance along Yemen’s Red Sea coast has raised fears that Saudi oil exports diverted away from Hormuz could face disruption at a second chokepoint. The US Navy has remained on high alert as the Houthis move closer to Bab el-Mandeb.
The Houthis said Sunday that four commanders of Saudi-backed Yemeni forces were killed and five others wounded in operations near Bab al-Mandab, according to the group-run Saba news agency.
The combination of pressure at Hormuz, attacks on Saudi infrastructure and Houthi gains near Bab el-Mandeb is narrowing the region’s alternatives at a time when diplomatic efforts remain divided over the terms of any maritime settlement.
With the Oman meeting now postponed and Washington and Tehran publicly at odds over the agenda for negotiations, there is no clear timetable for a diplomatic breakthrough even as the economic and military costs of the conflict continue to rise.
