U.S. officials said they were expecting a response from Iran to a fresh peace proposal as a month-long ceasefire between the two nations largely remained in place, even as localized clashes and military activity continued across the region.
Diplomacy and negotiations
Secretary of State Marco Rubio, speaking in Rome, said Washington expected Tehran’s reply “at some point” and expressed hope it would be a serious offer that could open a path to substantive negotiations. Vice President JD Vance was meeting in Washington with Qatari Prime Minister Sheikh Mohammed bin Abdulrahman bin Jassim Al-Thani, who has acted as a conduit on sensitive issues; Qatari officials have signaled a high probability of a deal. U.S. and Iranian officials both emphasized that a diplomatic outcome is preferred, even as each side accused the other of recent violations.
International reactions
U.N. Secretary-General António Guterres urged both Washington and Tehran to exercise maximum restraint after reports of exchanges of fire in the Strait of Hormuz, warning that further escalation could undermine diplomatic efforts. Iran’s U.N. ambassador wrote to the Security Council and Guterres, saying recent U.S. actions in the Gulf could have catastrophic consequences and urging the U.S. to avoid provocative behavior.
Military moves and maritime incidents
U.S. Central Command said American forces have redirected 57 commercial vessels and disabled four as part of a blockade intended to prevent ships from entering or leaving Iranian ports. In separate actions, U.S. forces reported firing on two Iran-flagged oil tankers to stop them from docking in violation of the blockade, and a prior strike disabled another tanker’s rudder.
CENTCOM also reported that three U.S. Navy destroyers — USS Truxtun, USS Mason and USS Rafael Peralta — were the target of missiles, drones and small-boat attacks while transiting the Strait of Hormuz. U.S. officials described the incidents as attacks that were repelled and said American forces conducted “self-defense strikes” against Iranian military facilities, including drone and missile launch sites.
Iran described the truce with the U.S. as “nominal” after the exchange of fire and accused Washington of breaching the ceasefire. Tehran said it had launched additional strikes and reported wounded and missing sailors after confrontations in the Hormuz area. U.S. officials maintained that no U.S. ships were hit in the incidents.
Regional air defenses and casualties
The United Arab Emirates reported intercepting ballistic missiles and drones it said were launched by Iran, and said debris from interceptions moderately wounded three people. The UAE said its defenses have intercepted hundreds of Iranian projectiles and drones since the wider conflict began.
In Lebanon, continued fighting between Israeli forces and Hezbollah led to civilian deaths and injuries. Lebanese authorities reported thousands killed and more than a million displaced since fighting escalated in March; the health ministry gave a toll of 2,759 killed and over 8,500 wounded. Hezbollah said it launched missiles at an Israeli military base in response to Israeli strikes that killed a senior commander; Israel reported intercepting launches and said some strikes fell in open areas.
Israel and Lebanon
Washington is hosting further talks between Lebanon and Israel aimed at reaching a lasting peace and security arrangement. These negotiations follow earlier rounds that produced a ceasefire understood to be in force between the two governments; fighting between Israel and Hezbollah has continued despite the agreement, and evacuation warnings and strikes in southern Lebanon have persisted.
Sanctions and law enforcement
The U.S. Treasury announced a new round of sanctions targeting 10 individuals and companies accused of supporting Iran’s drone and ballistic missile programs, including entities based in China, Dubai, Hong Kong and Belarus. The Treasury said the targets served as intermediaries providing financial, material or technological support that enabled Iran’s Shahed-series UAVs and missile activities. The State Department added four more entities to its sanctions list.
Separately, Bahrain announced the arrest of 41 people alleged to be linked to a group affiliated with Iran’s Revolutionary Guard; investigations were reported to be ongoing. In Israel, security services arrested four people accused of having spied for Iran as minors, including three soldiers; authorities said the suspects had carried out reconnaissance and security-related tasks for Iranian intelligence elements.
Regional economic and environmental impacts
Satellite imagery reviewed by analysts showed a large oil slick emanating from the area around Kharg Island, Iran’s main crude export terminal. Observers estimated tens of thousands of barrels had spilled; it was unclear whether the leak was the result of an attack, a malfunction, or other causes. Environmental experts said the slick may dissipate offshore but could threaten marine habitats depending on weather and currents.
Southeast Asian response
Leaders of ASEAN adopted a contingency plan to limit the war’s impact on the region, proposing measures such as coordinated emergency fuel sharing, planning a regional power grid and fuel stockpiles, promoting electric vehicles and studying civilian nuclear options. Officials acknowledged the difficulty of implementing some steps quickly, including establishing regional fuel reserves.
Other developments
Iran’s leadership figures reiterated the strategic value they place on control of the Strait of Hormuz. One adviser compared that control to possessing an “atomic bomb” in terms of influence over global energy flows. Iran has taken steps it says assert greater authority over transit through the strait, including creating an authority to oversee passage and collect fees, according to reporting.
President Trump repeatedly said the ceasefire with Iran remained in effect despite the recent exchanges and described U.S. strikes on Iranian targets as limited “self-defense” actions. He warned Tehran that a deal should be reached quickly and framed continued U.S. pressure in stark terms.
Outlook
Diplomatic momentum hinges on Tehran’s formal response to the U.S. proposal. U.S. officials signaled cautious optimism but stressed that any agreement must be credible and begin a serious negotiation process. At the same time, continued firefights, maritime interdictions and sanctions show how fragile the de-escalation remains and how quickly localized clashes could complicate broader talks.
