Tensions between the United States and Iran remain unresolved as fresh fighting erupted in the Gulf, complicating diplomatic efforts to convert a tenuous ceasefire into a lasting settlement. Over the past several days the most intense clashes since the ceasefire began have taken place in and near the Strait of Hormuz, and the United Arab Emirates reported a renewed Iranian strike on Friday.
U.S. officials have indicated they presented Tehran with a proposal intended to formally end hostilities, a step Washington said should precede discussions on other divisive issues such as Iran's nuclear program. U.S. Secretary of State Marco Rubio, speaking in Rome, said the administration expected a reply on Friday, though an Iranian foreign ministry spokesperson said Tehran was still considering its response.
Clashes test the ceasefire
Skirmishes were reported between Iranian forces and U.S. vessels in the Strait of Hormuz on Friday, according to Iranian semi-official media. One Iranian agency later quoted an unnamed military source saying that hostilities had eased but cautioned that further encounters could occur.
The U.S. military reported striking two Iran-linked vessels that were attempting to enter an Iranian port, using a fighter jet to target their smokestacks and compel them to withdraw. Since the outbreak of the conflict following U.S.-Israeli airstrikes across Iran on February 28, Tehran has substantially restricted non-Iranian shipping through the strait. Prior to the war, roughly one-fifth of the world’s oil supply transited the narrow waterway.
Last month Washington imposed a blockade on Iranian ships. A U.S. intelligence analysis, as described by a U.S. official familiar with the assessment, concluded Iran could resist significant economic hardship from a U.S. naval blockade of Iranian ports for approximately another four months. That assessment, according to the same official, complicates questions about how much leverage President Donald Trump can exert over Tehran at a moment when the conflict has attracted criticism from voters and U.S. partners.
A senior intelligence official later described as false certain "claims" about the CIA analysis. The range of public statements underscores competing narratives inside the U.S. government about the potential effectiveness and timing of economic and military pressure on Iran.
Escalation reaches the Gulf states
Violence has extended beyond the Strait of Hormuz. The UAE said its air defenses engaged two ballistic missiles and three drones from Iran on Friday. The country reported three people received moderate injuries in that incident. Iran has targeted the UAE and other Gulf states that host U.S. military facilities during the course of the conflict.
Authorities in the UAE characterized this week's strikes as a major escalation in response to a U.S. move called "Project Freedom," an initiative President Trump announced to escort ships through the strait. The president paused that operation after 48 hours. Speaking on Thursday, he said the ceasefire that was declared on April 7 was holding despite the recent flare-ups; Iran has accused the U.S. of breaching the same ceasefire.
"Every time a diplomatic solution is on the table, the U.S. opts for a reckless military adventure," Foreign Minister Abbas Araqchi said on Friday.
Iranian state media reported casualties from a U.S. Navy strike on an Iranian commercial vessel late on Thursday, saying one crew member was killed, 10 were wounded and six were missing.
Diplomacy alongside pressure
While the U.S. is continuing diplomatic outreach, it has also intensified sanctions aimed at constraining Tehran's military procurement. In the days leading up to President Trump's scheduled trip to China, the U.S. Treasury announced sanctions on 10 individuals and companies for assisting Iran's military in obtaining weapons and raw materials used to construct Shahed drones. The sanctions included entities in China and Hong Kong. Treasury officials said they are prepared to act against foreign firms that facilitate illicit Iranian commerce and could impose secondary sanctions on financial institutions linked to such activity, including those connected to independent oil refineries in China.
U.S. officials continue to press allies to support efforts to reopen the Strait of Hormuz to international shipping. After meeting with Italy's prime minister, Secretary Rubio questioned why some partners were not aligned with Washington's approach, warning of the precedent that might be set if Tehran gains effective control of an international waterway.
Implications and stakes
The recent exchanges of fire illustrate a fragile balance in which diplomatic and military measures are being deployed simultaneously. The presence of direct clashes at sea and missile and drone strikes against Gulf states complicates efforts to stabilize the situation, and competing assessments of the efficacy of a blockade or sanctions feed into broader debates within the U.S. government about leverage and timing. Tehran's actions against shipping lanes and Gulf neighbors, paired with Washington's sanctions campaign, leave regional security and global energy logistics central to the unfolding picture.
