Top Iranian negotiators and the foreign minister met Qatar’s prime minister in Doha on May 25 as mediators pressed for a memorandum of understanding that could end nearly three months of war and reopen the Strait of Hormuz, an official briefed on the visit said. Discussions focused on reopening the strait, Tehran’s stockpile of highly enriched uranium, and the possible release of frozen Iranian funds; Iran’s central bank governor attended parts of the talks. U.S. President Donald Trump and aides have described a draft as “largely negotiated” but urged patience, while Secretary of State Marco Rubio said diplomacy would get every chance before other options are considered. Iran and U.S. officials cautioned a deal was not imminent. Pakistan’s mediators reported “encouraging” progress; Israeli leaders warned Israel must retain freedom to act against regional threats. Markets responded to the prospect of a deal: oil and the dollar fell, gold and equities rose, and traders recalibrated rate expectations amid concerns about inflation and global energy supply.

Diplomacy between the United States and Iran accelerated between May 23-26 as mediators reported progress toward a memorandum of understanding intended to extend a ceasefire, reopen the Strait of Hormuz and set a timetable for later negotiations on Iran’s nuclear programme. U.S. President Donald Trump said a framework was "largely negotiated" while warning negotiators not to rush; Secretary of State Marco Rubio said a "pretty solid" proposal could be imminent. Iranian spokespeople, however, cautioned that a final deal was not close. Reports describe a staged framework — formally ending active hostilities, resolving Hormuz access and launching a 30‑day window for broader talks — with potential elements including disposal or supervision of highly enriched uranium, lifting of some sanctions and release of frozen funds. Regional actors including Pakistan, Qatar and Gulf states have been engaged; Israel has sought assurances it may still act against threats in Lebanon. Markets reacted to the developments: oil and the dollar fell and Asian stocks rose. The diplomacy faces new strain after U.S. strikes were reported on southern Iranian targets on May 26, underlining the fragility of the process.

U.S. forces carried out fresh strikes in southern Iran on May 25-26, targeting boats alleged to be laying mines and missile launch sites, with U.S. Central Command saying the actions were defensive and intended to protect troops. The strikes coincided with high-level Iranian envoys — including Iran’s top negotiator and foreign minister — holding talks in Doha with Qatari and Pakistani mediators on a memorandum of understanding with Washington to end the three‑month war. The proposed framework reportedly would include a 60‑day ceasefire extension, steps to reopen the Strait of Hormuz (potentially within 30 days), and a time‑limited process to address Iran’s enriched uranium and sanctions relief. President Donald Trump described the draft deal as “largely negotiated” but later urged negotiators not to rush, while U.S. Secretary of State Marco Rubio said a “pretty solid” proposal was on the table. Iranian officials cautioned that a final agreement was not imminent and said they had downed a stealth drone. Israel, meanwhile, has signalled it will continue operations against Hezbollah in Lebanon. Energy markets and shipping routes reacted to the shifting prospects for a deal and the risk of renewed hostilities.

On May 25, 2026 U.S. Central Command said American forces carried out strikes in southern Iran targeting missile launch sites and Iranian boats reported to be attempting to emplace naval mines near the Strait of Hormuz. CENTCOM spokesman Capt. Tim Hawkins described the actions as “self‑defense” taken to protect U.S. troops and said forces were exercising restraint during the ongoing ceasefire that began in April. Explosions were reported in Bandar Abbas and nearby coastal towns including Sirik and Jask; Iran’s state media later said the situation in Bandar Abbas was under control and provided limited official comment. The strikes occurred as Iranian negotiators were in Doha for talks with U.S. counterparts and came amid public remarks by U.S. President Donald Trump about enriched uranium and broader regional concessions, including urging Arab states to sign the Abraham Accords. Details on damage, casualties and Iran’s operational response were not immediately clear, and both sides framed the strikes as compatible with continuing diplomacy.

Emergency crews in Garden Grove, California, worked over the Memorial Day weekend to avert a catastrophic failure at a GKN Aerospace storage tank holding about 6,000-7,000 gallons of methyl methacrylate. The tank overheated and began venting vapors on May 22-23, prompting mandatory evacuations covering roughly 40,000-50,000 residents and a state of emergency declared by Governor Gavin Newsom. Firefighters cooled the tank with water, brought in technical experts and conducted risky overnight inspections; by May 25 they reported a crack at the top of the tank that appears to have relieved pressure and reduced internal temperature (reported falling from readings near 100F to the low 90s). Officials said the threat of a boiling liquid expanding vapor explosion (BLEVE) has been eliminated, though evacuation orders and containment precautions remain while teams monitor for leaks. Federal agencies including the EPA and FEMA have been integrated into the response, air monitoring has not detected hazardous concentrations, and local prosecutors have opened an investigation; residents have filed at least one class-action suit against the company.
