The U.S. military announced another round of strikes against Iranian targets in response to an early-morning attack on a Panama-flagged tanker in the Strait of Hormuz, marking the most serious uptick in hostilities since the two sides agreed to an interim peace arrangement two weeks ago.
U.S. Central Command said its forces launched the strikes after the tanker was struck by what it described as an Iranian drone. In a statement, the command said "Iran was given a chance to honor the ceasefire agreement but elected not to." The U.S. characterized the operation as "in direct response to continued Iranian aggression against commercial shipping," and specified that the targets included Iranian military surveillance assets, communications nodes, air defenses, drone storage facilities and sites used for mine-laying.
Separately, a U.S. defense official later told Fox News that the strikes on Iranian targets were complete.
Hours earlier, the Panama-flagged tanker had been hit in the strait. Britain’s UKMTO maritime security agency reported the vessel suffered damage to its bridge; all crew members were reported safe. The Joint Maritime Information Center, which is run by a coalition of navies responsible for protecting commercial shipping, raised its security threat level following the recent string of incidents.
Iranian state broadcaster IRIB reported early Sunday local time that explosions were heard in the southern port area of Sirik, but provided no additional operational detail. Iranian state television also carried accounts that the Islamic Revolutionary Guard Corps fired "warning shots" at unspecified vessels attempting to navigate channels Iran has not approved. Those broadcasts said other ships are now seeking Iranian permits before attempting to transit the strait.
Iran has not issued direct confirmations of specific ship attacks, but Iranian officials have framed recent moves as efforts to assert control over the Strait of Hormuz - the world's most important energy shipping lane. The incident on Saturday followed a strike on a cargo ship on Thursday that had already set off the latest round of escalation.
U.S. officials said Washington previously struck Iranian targets overnight, and Iran said it retaliated on Saturday by striking targets it linked to U.S. forces. Bahraini authorities, in turn, reported an Iranian drone attack. Tehran’s foreign ministry described its own actions as "defensive" strikes against military targets connected to the United States. Meanwhile, Iranian state television reported that the Revolutionary Guards delivered "a decisive response" after U.S. forces struck a communications tower in the port city of Sirik; Iran’s Mehr news agency said the port continued to operate normally, with no reported damage to facilities or equipment.
The exchanges come amid competing interpretations of the interim memorandum of understanding signed two weeks ago to halt four months of open conflict. Each side accuses the other of breaching the agreement: Washington has signaled Iran failed to uphold its commitments, while Tehran has accused the United States of not sustaining a promised ceasefire in Lebanon and of supporting proxy forces across the region.
Iran has repeatedly cited concerns about U.S. policy in Lebanon as a reason for its own posture. The country’s officials argue that Washington has not kept to the letter of the memorandum by allowing ongoing operations - including Israeli actions in Lebanon - that Tehran sees as incompatible with the ceasefire’s spirit. Israel invaded parts of Lebanon in March in pursuit of Hezbollah, the Iran-backed militant group, and the two countries have on several occasions agreed to U.S.-brokered ceasefires. The latest Israel-Lebanon agreement, announced on Friday, has had only limited effect on the broader situation, with Israel maintaining it will not withdraw from territory it has seized and Hezbollah refusing to disarm while Israeli forces remain.
Lebanese state television reported an Israeli drone strike on Saturday in the Nabatiyeh area of southern Lebanon, a region that has seen repeated Israeli attacks during the conflict. The Israeli military said it targeted an individual it said posed a threat to its forces. Hezbollah deputy leader Naim Qassem rejected the new Israel-Lebanon agreement as a surrender and described it as "null and void." The fallout from conflict in the area has left hundreds of thousands of Lebanese, mainly Shi’ite Muslims, unable to return to homes in territory occupied by Israeli forces, contributing to broader public anger about the terms of the ceasefires.
On the Israeli side, Defence Minister Israel Katz praised the recent agreement, saying it allows Israel to maintain control of what he described as a security zone in Lebanon and prevents displaced residents from returning to those areas.
Back in Tehran, Mohsen Rezaei, an adviser to Iran’s supreme leader, argued that Washington had violated the memorandum of understanding by supporting proxy forces in the region and by contributing to tensions in the Strait of Hormuz. Iran has also carried out strikes against neighboring Gulf states that host significant U.S. military installations.
The maritime disruptions over the course of the conflict have had a direct impact on commercial traffic through the Gulf. Hundreds of ships, including oil tankers, were blockaded inside the Gulf earlier in the war. Over the past two weeks, as vessels began departing the blockaded area, oil supplies have surged back into global markets and prices have fallen close to pre-war levels. Washington has been encouraging shipping to transit via a southern lane along the coast of Oman, while Iran favors a northern route that would run through its territorial waters - a route Tehran seeks to control and ultimately charge fees for.
Ebrahim Azizi, head of the Iranian parliament’s national security committee, warned on Saturday that any vessel failing to comply with Iran’s shipping directives would face a decisive response.
In Washington, U.S. Vice President JD Vance, who serves as the administration’s chief negotiator on the conflict, reiterated the American interpretation of events and placed responsibility for renewed violence on Iran. "Iran signed a ceasefire agreement. We have honored it. If they have disagreements about how the MOU is being applied, they can pick up the phone. But violence will be met with violence," Vance said on X.
The rapid sequence of attacks and counterattacks, and the associated messaging from both capitals, underscores the fragility of the ceasefire arrangement and the risk of further disruption to commercial maritime traffic and regional military stability. For commercial operators and markets sensitive to oil supply, the immediate effects have included raised security alerts, damaged vessels, and continued uncertainty about safe transit routes through the Strait of Hormuz.
Summary
The U.S. carried out strikes on Iranian military and maritime-related targets after a Panama-flagged tanker was struck in the Strait of Hormuz, an incident that followed a cargo ship attack earlier in the week. Both sides accuse the other of violating a two-week-old interim ceasefire, and the confrontations have intensified concerns about commercial shipping safety, maritime route control and regional stability. Officials on both sides offered public statements blaming the opposite party; U.S. authorities say strikes were in direct response to Iranian aggression against shipping, while Iranian sources describe their actions as defensive and assertive moves to control the strait.
Key points
- The U.S. launched fresh strikes targeting Iranian surveillance, communications, air defense, drone storage and mine-laying facilities after a Panama-flagged tanker was hit in the Strait of Hormuz.
- Both Washington and Tehran accuse each other of violating an interim ceasefire reached two weeks earlier; the situation has included attacks on commercial vessels and strikes linked to U.S. forces.
- Disruptions in the Strait of Hormuz have direct implications for energy markets and shipping routes - hundreds of ships were blockaded earlier in the conflict and recent re-openings have pushed oil prices down toward pre-war levels as supply returned to markets.
Risks and uncertainties
- Escalation in military strikes could further threaten commercial shipping through the Strait of Hormuz, raising costs and insurance premiums for energy and shipping sectors.
- Ambiguity over control of transit routes - between Iran’s preferred northern route under its control and the U.S.-endorsed southern lane along Oman - creates operational uncertainty for maritime logistics and energy transport.
- Political and military responses tied to interpretations of the interim ceasefire, including actions tied to Lebanon and Israel, add unpredictability to regional security dynamics, affecting markets sensitive to geopolitical risk.
