Relative calm returned to the strategic waterway after several days of clashes involving Iranian and US forces near the strait, a critical global energy chokepoint through which roughly one-fifth of the world’s oil supply passed before the conflict erupted in late February.

US Secretary of State Marco Rubio said Washington was awaiting Tehran’s response to a proposal that would formally end hostilities before broader negotiations begin on disputes including Iran’s nuclear program.

More than 24 hours after Rubio said a response was expected “within hours,” Iranian authorities had not publicly reacted.Rubio met Qatari Prime Minister Mohammed bin Abdulrahman Al-Thani in Miami on Saturday, where both sides discussed cooperation to “deter threats and promote stability and security across the Middle East,” according to US State Department spokesperson Tommy Pigott.

The statement did not directly reference Iran.The Qatari LNG tanker Al-Kharaitiyat was sailing toward the Strait of Hormuz en route to Pakistan, according to LSEG shipping data. Sources familiar with the matter said Iran had approved the transit to signal goodwill toward Qatar and Pakistan, both of which have played mediating roles during the conflict.

If completed, the voyage would mark the first passage of a Qatari LNG carrier through the strait since fighting began following US-Israeli airstrikes across Iran on Feb. 28.Iranian military officials nevertheless maintained a confrontational tone.

Brigadier General Mohammad Akraminia, an Iranian army spokesperson, warned countries enforcing US sanctions against Tehran that they would “face difficulties crossing the Strait of Hormuz,” according to the semi-official Tasnim news agency.Recent flare-ups have tested a ceasefire announced on April 7, with clashes intensifying in and around the strait over the past week.

The United Arab Emirates said on Friday that its air defenses intercepted two ballistic missiles and three drones launched from Iran, leaving three people moderately injured.Iran has repeatedly targeted Gulf states hosting US military facilities during the conflict, while accusing Washington of violating the ceasefire through continued naval operations and sanctions enforcement.

On Friday, Iranian media reported sporadic clashes between Iranian forces and US vessels in the strait. The US military separately said it struck two Iran-linked vessels attempting to enter an Iranian port, forcing them to reverse course after a fighter jet targeted their smokestacks.

Iran’s Islamic Revolutionary Guard Corps responded with threats to retaliate against US interests in the region if Iranian commercial vessels were attacked again. Iranian media quoted the Guards as saying any strike on Iranian tankers would trigger a “heavy attack” on American facilities and ships.

The conflict has disrupted shipping traffic and heightened volatility in global energy markets. Tehran has largely restricted non-Iranian shipping through the Strait of Hormuz since the war began, significantly reducing maritime flows through one of the world’s most strategically vital waterways.

US President Donald Trump, who is scheduled to visit China next week for talks with President Xi Jinping, has faced mounting pressure from allies and financial markets to stabilize the situation. The war has strained relations with European partners and raised fears of broader economic fallout tied to energy supply disruptions.

Speaking after talks with Italian Prime Minister Giorgia Meloni, Rubio questioned why some US allies had not more forcefully backed efforts to reopen the strait, arguing that allowing Iran to dominate an international shipping lane would establish a dangerous precedent.

German Chancellor Friedrich Merz said European governments remained aligned with Washington on preventing Iran from acquiring nuclear weapons while attempting to narrow diplomatic differences over the conflict. Britain said it would deploy a warship to the Middle East in preparation for a potential multinational maritime security mission alongside France once conditions permit.

At the same time, Washington expanded economic pressure on Tehran. The US Treasury on Friday imposed sanctions on 10 individuals and companies, including entities in China and Hong Kong, accused of helping Iran’s military procure weapons components and materials linked to the production of Shahed drones.

A report in the Washington Post citing a CIA assessment said Iran could withstand US maritime pressure for several more months without severe economic damage, potentially limiting Washington’s leverage. A senior US intelligence official later rejected the characterization of the assessment as inaccurate.

Iranian Foreign Minister Abbas Araghchi accused Washington of undermining diplomatic efforts, saying Friday that “every time a diplomatic solution is on the table, the US opts for a reckless military adventure.”

The ministry said in a statement that defense systems were “actively engaging” aerial threats and urged residents not to approach or photograph debris from intercepted projectiles.The attack came hours after the U.S. military said American naval forces in the Strait of Hormuz had intercepted Iranian attacks targeting three U.S. Navy vessels late Thursday and carried out retaliatory strikes against Iranian military facilities linked to operations against American forces.

United States Central Command said in a social media statement that U.S. forces responded to “unprovoked Iranian attacks” with what it described as self-defense strikes. The military said no American ships were hit and added that Washington did not seek further escalation but remained prepared to defend U.S. personnel and assets in the region.

Donald Trump told reporters in Washington that the ceasefire agreement between Tehran and Washington was still in effect despite renewed hostilities.

The latest violence threatens a truce that has largely held since April 8 after nearly six weeks of conflict triggered by U.S. and Israeli strikes on Iranian targets beginning Feb. 28.The UAE was among the Gulf states most affected during the conflict, facing repeated missile and drone attacks that authorities attributed to Iran.

Emirati officials said this week that strikes reported on Monday and Tuesday marked the first attacks on UAE territory since the ceasefire took effect.

According to UAE authorities, the country has been targeted by more than 2,000 drones, hundreds of ballistic missiles and dozens of cruise missiles since the war began. Officials said most were intercepted, but the attacks killed at least 13 people, injured more than 200 and damaged energy infrastructure and prominent buildings.

Other Gulf Arab countries also reported attacks during the conflict despite maintaining they were not directly participating in the U.S.-Israeli military campaign against Iran.On Thursday, the UAE announced the formation of a national committee to document what it described as Iranian attacks and the resulting human, economic and material losses, laying groundwork for potential legal action against Tehran.

State news agency WAM said the committee, chaired by the UAE attorney general, would gather evidence according to internationally recognized legal and technical standards to support future claims for accountability, reparations and justice.The move followed renewed diplomatic tensions after the UAE condemned statements by Iranian officials accusing Abu Dhabi’s security cooperation with Washington of threatening Iran’s national interests.

The United Arab Emirates Ministry of Foreign Affairs said the country’s defense partnerships were a sovereign matter.

Efforts to secure a broader settlement remain stalled after talks hosted by Pakistan last month between U.S. and Iranian representatives ended without a comprehensive agreement to halt the conflict permanently.

U.S. Central Command said the vessel, identified as the Sevan, was intercepted by a Navy helicopter launched from the guided-missile destroyer USS Pinckney during operations aimed at enforcing restrictions on Iranian oil and gas shipments.

The military described the Sevan as part of a 19-vessel “shadow fleet” accused of transporting Iranian petroleum products, including oil, propane and butane, to foreign markets in violation of U.S. sanctions.

According to Central Command, the ship complied with orders to reverse course and is now heading back toward Iran under U.S. escort.The interception marks the latest maritime enforcement action under a U.S.-led blockade intended to restrict Iranian energy exports and reduce revenue flows to Tehran amid heightened regional tensions.

U.S. officials said the targeted fleet had been sanctioned by the United States Department of the Treasury for facilitating the transport of billions of dollars’ worth of Iranian energy products through covert shipping networks often involving opaque ownership structures and flag changes.

“These vessels are part of a sanctions evasion network designed to conceal the origin and destination of Iranian exports,” Central Command said in its statement.Since the start of the blockade, the U.S. military said 37 vessels have been redirected, reflecting an expanded effort to enforce sanctions through direct maritime interdiction rather than financial restrictions alone.

The Arabian Sea has become a focal point for such operations due to its strategic role in shipping routes connecting the Gulf, South Asia and global energy markets.Washington has increased pressure on Iranian oil exports as part of broader efforts to constrain Tehran’s regional influence and funding channels, particularly amid ongoing instability across the Middle East and heightened tensions involving U.S. forces in the region.

Iran has repeatedly criticized U.S. maritime sanctions enforcement as unlawful and has accused Washington of disrupting freedom of navigation and international trade.

The latest interception comes as scrutiny of tanker movements linked to Iran has intensified, with governments and shipping regulators monitoring so-called shadow fleets used to bypass sanctions through ship-to-ship transfers and concealed cargo documentation.

No injuries or military confrontation were reported during the interception of the Sevan, and Central Command did not specify the vessel’s final destination before it was ordered to turn back.

No reason was provided for the abrupt exit of Phelan, the Navy’s top civilian official, whose departure comes at a time of heightened operational activity, including a blockade of Iranian ports and actions targeting vessels linked to Tehran during a fragile ceasefire in the ongoing regional conflict.

Pentagon spokesman Sean Parnell confirmed the move in a statement, while the administration named Hung Cao, the current undersecretary and a retired Navy captain, as acting secretary. Cao, a former combat officer and political candidate in Virginia, assumes the role immediately.

Phelan’s departure adds to a series of leadership changes under Defense Secretary Pete Hegseth, who has removed several senior military figures since taking office last year. Those include Randy George, the Army’s top uniformed officer, as well as earlier dismissals of Lisa Franchetti and Jim Slife.

Charles Q. Brown Jr. was also removed from his post as chairman of the Joint Chiefs of Staff.The timing of Phelan’s exit appeared sudden. He had addressed a major Navy conference in Washington a day earlier and held meetings with lawmakers, including members of the House Armed Services Committee, to discuss shipbuilding plans and budget priorities, according to official communications.

Phelan, a private investment executive and founder of Rugger Management LLC, had limited prior government or military leadership experience before his nomination in late 2024. His background included advisory work with Spirit of America, a nonprofit supporting defense-related initiatives in Ukraine and Taiwan.

His tenure coincided with an expanded U.S. naval presence globally. The Navy currently has multiple aircraft carriers deployed or en route to the Middle East, and U.S. forces remain positioned for potential renewed operations should the ceasefire with Iran collapse.

Separately, naval assets have supported counter-narcotics operations in the Caribbean and were involved in the January capture of Venezuelan leader Nicolás Maduro.Cao, who succeeds Phelan in an acting capacity, is a Vietnam-born refugee who later graduated from the U.S. Naval Academy and served in special operations units, including deployments in Iraq, Afghanistan and Somalia.

He previously ran unsuccessful campaigns for the U.S. Senate and House of Representatives in Virginia and has publicly criticized diversity and inclusion initiatives in the military, as well as COVID-19 vaccine mandates imposed on service members.

His appointment comes as the Trump administration continues to recalibrate defense leadership and policy priorities, including a broader rollback of diversity programs across the armed forces.

Saudi political analyst Faisal Ibrahim Al Shammari confirmed via social media that the U.S. Navy’s Fifth Fleet, headquartered in Manama, Bahrain, has been placed on high alert, with dependents of service members already beginning to evacuate the country.

The precautionary steps follow undisclosed threats and a “rapid shift in the security posture” of U.S. military assets in the Gulf. According to Al Shammari, the State Department’s decision was driven by intelligence assessments indicating a heightened risk of Iranian-sponsored reprisals in the region—possibly in response to recent clandestine developments.

Iraq: U.S. Embassy Prepared for Emergency Exit

Sources indicate that the U.S. Embassy in Baghdad has been instructed to prepare for a potential emergency evacuation. Military personnel stationed in Iraq have reportedly been placed on elevated alert, with contingency plans being reviewed for an expedited drawdown if the security situation deteriorates.

The shift in posture signals growing unease in Washington over Iranian proxy activity and maritime threats amid an increasingly volatile geopolitical landscape.

Regional Readiness Tightens

In a related development, the UK Maritime Trade Operations (UKMTO) issued an urgent security alert for vessels transiting the Persian Gulf, warning that “escalating tensions” may trigger “military activity targeting commercial shipping.”

American vessels operating in Gulf waters are being advised to exercise maximum caution, while security analysts warn that the current environment mirrors patterns seen ahead of prior naval confrontations.

The evacuation orders and high-alert statuses underscore mounting fears of a sudden clash in the region, particularly between the United States and Iran. Gulf nations—especially those hosting U.S. military assets—are closely watching the situation, as diplomatic and military backchannels work to prevent open confrontation.

As of now, there has been no official comment from the U.S. State Department regarding the troop movements or embassy evacuation plans.

The situation remains fluid.
