Kharg Island, located about 15 to 16 nautical miles off the coast of Iran, serves as a critical export hub handling roughly 90 percent of Iran’s crude oil shipments, making it a central node in the country’s energy infrastructure and a key source of revenue.

Trump has publicly suggested the United States could take control of the island to assert influence over Iran’s oil and gas sector, while also acknowledging that a ground operation would be difficult and politically sensitive. In remarks cited by US media, he indicated reluctance to deploy ground troops, while suggesting limited military options could still be considered.

The United States military has already conducted strikes on the island earlier this year, targeting more than 90 military installations, including naval mine storage sites and missile facilities, while reportedly sparing oil infrastructure to avoid long-term economic disruption, according to Central Command assessments cited in reporting.

However, analysts cited by Arab News and Reuters warned that any attempt to physically occupy the island would likely escalate the conflict. Experts from the Foundation for Defense of Democracies said an occupation could prolong the war and fail to deliver a decisive strategic outcome.

Former US Central Command commander Joseph Votel was cited as saying that while a relatively small force could theoretically hold the island, such troops would require extensive logistical support and would remain highly vulnerable to attack.

Iranian officials have reinforced defenses around the island, deploying air-defense systems, mines, and other military assets in surrounding waters. Iranian parliamentary speaker Mohammad Bagher Ghalibaf warned that Iranian forces were prepared to respond forcefully to any incursion, including targeting regional infrastructure.

Military analysts also cautioned that any US presence could be exposed to asymmetric tactics, including drone surveillance and propaganda dissemination of battlefield losses, potentially increasing political pressure on Washington.

Despite heightened tensions, Trump has recently indicated a pause in new strikes following what he described as progress in negotiations with Tehran, suggesting that diplomatic channels remain active alongside military signaling.

In a social media post, Trump said the United States would strike Iran “VERY HARD TONIGHT” and declared that Washington would “assume total control” of Iran’s oil and gas sector, including the strategically important Kharg Island export terminal, at some point in the future.

Trump did not provide details on how such a move could be carried out. Kharg Island is the main hub for Iranian crude exports and a critical source of revenue for the country’s economy. The island is located off Iran’s Gulf coast and serves as a central artery for the nation’s energy shipments.

The comments came as the U.S. military launched a new wave of strikes against Iranian military targets, broadening a campaign that appeared more extensive than operations conducted a day earlier.

U.S. Central Command (CENTCOM) said American forces carried out additional strikes against Iranian surveillance systems, communications infrastructure and air defense facilities. According to the command, U.S. Marine Corps, Air Force and Navy assets employed precision-guided munitions against targets viewed as threats to American personnel and commercial maritime traffic in regional waters.

CENTCOM described the operations as defensive measures conducted in response to what it called continuing Iranian aggression.

Iran condemned the attacks, with the Foreign Ministry saying the latest U.S. military action effectively rendered a ceasefire that had held for nearly two months “practically meaningless.”

In a statement, the ministry said the strikes represented a violation of international norms and warned that responsibility for any serious consequences would rest with U.S. leaders.

Speaking at the White House, Trump said military pressure on Iran would continue while diplomatic channels remained open.

“We’re going to be attacking them very hard,” Trump told reporters, while reiterating his administration’s desire for a negotiated settlement.

The president said Washington sought an agreement that would permanently prevent Iran from acquiring a nuclear weapon. He claimed Tehran had accepted the principle of foregoing nuclear arms but said a final accord had not been concluded.

Defense Secretary Pete Hegseth echoed the administration’s warnings during a visit to the U.S. naval base at Guantanamo Bay, Cuba.

Hegseth said the strikes were intended to protect American forces and cautioned Tehran against escalating the confrontation further.

“Iran would be unwise to challenge us further,” he said.

The latest exchange has heightened concerns about a broader regional conflict involving the United States and Iran, while adding uncertainty to energy markets and international diplomatic efforts aimed at reducing tensions in the Middle East.

Despite the military escalation, U.S. officials continued to emphasize that diplomacy remains Washington’s preferred path, provided any future agreement includes lasting guarantees that Iran will not develop a nuclear weapons capability.

U.S. President Donald Trump said on Friday he expected Tehran to respond “supposedly tonight” to a proposal delivered through Pakistani mediators, but no official Iranian reply had been made public by Saturday evening.Iranian Foreign Minister Abbas Araghchi questioned Washington’s intentions during a phone call with his Turkish counterpart, according to remarks published by Iran’s ISNA news agency.

“The recent escalation of tensions by American forces in the Arabian Gulf and their numerous actions in violating the ceasefire have added to suspicions about the motivation and seriousness of the American side in the path of diplomacy,” Araghchi said.The comments followed a confrontation on Friday in which a U.S. fighter jet fired on and disabled two Iranian-flagged tankers that Washington said had challenged an American naval blockade targeting Iranian ports.

An Iranian military official, quoted by local media, said Iran’s navy had retaliated against what he described as “American terrorism with strikes,” adding that the clashes had since ended.The incident came less than a day after another flare-up in the Strait of Hormuz, one of the world’s most strategically important shipping routes for global oil exports.

U.S. Secretary of State Marco Rubio reiterated Friday that it was “unacceptable” for Tehran to exert control over the waterway, through which a substantial share of global crude shipments passes.The Trump administration has sought to reopen commercial navigation through the strait after Iran restricted maritime access following the outbreak of conflict on Feb. 28, triggered by joint U.S.-Israeli strikes on Iranian targets.

Washington later imposed a blockade on Iranian ports, escalating tensions across Gulf shipping lanes and contributing to volatility in international energy markets.Iranian Foreign Ministry spokesperson Esmaeil Baqaei said Friday the latest U.S. proposal remained “under review.”

Meanwhile, Sheikh Mohammed bin Abdulrahman Al Thani met U.S. Vice President JD Vance in Washington on Friday to discuss Pakistani-mediated efforts to secure a longer-term settlement.Separately, satellite imagery indicated an oil slick spreading near Kharg Island, Iran’s principal oil export hub in the Gulf.

Monitoring group Orbital EOS estimated the slick initially covered more than 20 square miles before appearing to diminish by Saturday.The UK-based Conflict and Environment Observatory said the spill may have originated from damaged or leaking oil infrastructure, though the exact cause remained unclear.

Kharg Island plays a central role in Iran’s energy exports and has become increasingly sensitive amid the ongoing confrontation over Gulf shipping routes and oil flows.

The confrontation marked the latest escalation in a 10-week war that began with joint U.S.-Israeli strikes on Iran and has since destabilized shipping lanes, disrupted oil exports and widened hostilities across the Middle East.U.S. Central Command said an F/A-18 Super Hornet used precision-guided munitions against the two vessels to prevent them from continuing toward Iranian waters through the Gulf of Oman, a strategic maritime corridor connected to the Strait of Hormuz.

Iranian officials condemned the attack as a breach of the ceasefire and accused Washington of undermining ongoing diplomatic efforts.An Iranian military official told local media that naval forces had “responded to the violation of the ceasefire and to American terrorism with strikes,” adding that the clashes had subsequently ended.

The incident followed renewed tensions overnight in the Strait of Hormuz, a vital energy transit chokepoint through which a significant share of global oil shipments passes. An adviser to Iran’s supreme leader compared strategic control of the strait to possessing “an atomic bomb.”U.S. Secretary of State Marco Rubio said in Rome that Washington expected Tehran’s response later Friday to a new American proposal aimed at extending the truce to facilitate broader negotiations.

“It is unacceptable” for Iran to control the strategic waterway, Rubio told reporters, expressing hope Tehran would present “a serious offer.”At the White House, U.S. President Donald Trump said his administration anticipated receiving a formal Iranian response by nightfall.“I’m getting a letter supposedly tonight, so we’ll see how that goes,” Trump said.

According to regional officials, Washington delivered the latest ceasefire proposal through Pakistani mediators, seeking an extension of the Gulf truce to create space for negotiations over a permanent settlement.Iran’s Foreign Ministry spokesman Esmaeil Baqaei said the proposal remained “under review,” according to the ISNA news agency.

Iran’s ambassador to the United Nations, Amir Saeed Irvani, submitted a letter to the U.N. Security Council accusing the United States of violating the ceasefire through the tanker strikes.In Washington, Qatar’s Prime Minister Mohammed bin Abdulrahman Al Thani met U.S. Vice President JD Vance to discuss Pakistani-led mediation efforts aimed at securing a lasting peace arrangement.

Satellite imagery released Friday indicated an expanding oil slick off Iran’s Kharg Island, the country’s principal oil export terminal. Monitoring firm Orbital EOS estimated the spill covered more than 20 square miles off the island’s western coastline, though the cause was not immediately determined.

Kharg Island remains central to Iran’s oil export infrastructure and sits north of the Strait of Hormuz, where commercial shipping disruptions since February have contributed to heightened volatility in global energy markets.Iran largely closed the strait following the outbreak of war on Feb. 28, prompting sharp increases in oil prices and renewed security deployments by Western naval forces.

The United States later imposed a maritime blockade targeting Iranian ports.Trump earlier this week announced a naval initiative aimed at reopening the strait to commercial traffic before reversing course in favor of renewed diplomacy.On a parallel front in Lebanon, the Iran-backed militant group Hezbollah said it launched missiles toward an Israeli military base near Nahariya in response to Israeli strikes on Beirut’s southern suburbs and southern Lebanon.

Hours later, Hezbollah announced a separate drone attack targeting another Israeli base in the north.Israel has continued operations against Hezbollah despite an existing ceasefire agreement. On Wednesday, Israeli forces carried out their first strike in a month on Beirut’s southern suburbs, saying a senior Hezbollah commander had been killed.

Lebanon’s health ministry said Israeli strikes in the south killed 10 people on Friday, including women and children, while Lebanon’s civil defense agency said one of its personnel was also killed.The escalation comes ahead of planned direct negotiations between Israel and Lebanon in Washington next week, talks Hezbollah has publicly opposed.

Iran has rejected a U.S. ultimatum to reopen the Strait of Hormuz by a deadline set by former U.S. President Donald Trump, as military strikes intensified and diplomatic efforts led by Pakistan approached what officials described as a critical stage.

With hours remaining before the deadline, a senior Iranian source said Tehran would not reopen the strategic waterway without concessions from Washington that had not been offered. The Strait of Hormuz, a key global energy corridor, has effectively been closed by Iran to most international shipping since late February following joint U.S.-Israeli military actions.

Trump warned that failure to comply would result in large-scale destruction of Iranian infrastructure, including power grids and bridges. In a social media post, he stated that “a whole civilization will die tonight,” framing the moment as a pivotal point in global history.

The remarks drew criticism from legal experts, including a former U.S. State Department adviser now with the International Crisis Group, who said the language could be interpreted as a threat violating international norms.

Military activity escalated across Iran throughout the day. Strikes were reported on transport infrastructure, including railway and highway bridges, as well as an airport and a petrochemical facility. U.S. forces also targeted installations on Kharg Island, which hosts Iran’s primary oil export terminal.

Power outages were reported in parts of Karaj following damage to transmission lines and a substation.Iran signalled a broadening of its response. Officials warned that Gulf states aligned with Washington could face retaliatory strikes on critical infrastructure.

A senior Iranian source said such actions could disrupt electricity and water supplies in desert cities dependent on energy systems.Iran’s Revolutionary Guards issued a statement saying previous restraint had ended and that Tehran would seek to deprive the United States and its regional allies of oil and gas resources.

Iranian authorities also claimed responsibility for attacks on a vessel in the Gulf and on a major Saudi petrochemical facility in Jubail, where international energy companies operate.In parallel, reports emerged of an overnight strike on a synagogue in Tehran, which Iranian officials attributed to Israeli forces.

Footage aired by state media showed debris scattered across the site, including religious texts. Israel’s military did not immediately comment on the incident.Diplomatic efforts led by Pakistan continued amid the escalation.

Iranian officials said mediation attempts were “approaching a critical, sensitive stage,” with Islamabad relaying messages between the two sides. A proposal under discussion included a temporary ceasefire and partial reopening of the strait, with broader negotiations to follow.

However, Iranian sources said Tehran had rejected interim arrangements, insisting instead on a permanent cessation of hostilities, guarantees against future attacks and compensation for damage.Iran’s conditions, as outlined through official channels, also included maintaining control over the strait and introducing a mechanism to regulate transit, potentially involving fees.

Prior to the conflict, the waterway functioned as an open international route through which roughly one-fifth of global oil and liquefied natural gas supplies passed.Despite the intensifying conflict, global markets showed limited reaction, reflecting uncertainty over whether the U.S. would carry out the threatened escalation.

Trump has previously issued similar warnings but later stepped back, citing unspecified progress in talks, claims that Iranian officials have denied.On the ground, residents expressed concern over the prospect of further escalation.

A resident in Isfahan said she hoped the latest threats would not materialise, reflecting broader public anxiety as military actions continued.Iran maintains that any negotiations must follow a halt to U.S. and Israeli strikes and include the lifting of sanctions.

Without such measures, officials indicated that Tehran would continue its current posture, including restrictions on maritime transit through the Strait of Hormuz.

As the deadline approached, neither side signalled a willingness to compromise, raising the risk of further escalation in a conflict that has already disrupted regional stability and global energy flows.

The report said any action would likely fall short of a full-scale invasion, instead involving special operations forces and conventional infantry targeting locations such as Kharg Island and coastal areas near the Strait of Hormuz, a critical corridor for global oil shipments.

Washington has already moved thousands of Marines to the Middle East amid the month-long conflict. The first of two contingents arrived on an amphibious assault ship on Friday, according to the U.S. military.

Additional deployments under consideration include forces from the 82nd Airborne Division, alongside approximately 5,000 Marines being repositioned to the region. These reinforcements would add to an estimated 50,000 U.S. troops already stationed across the Middle East, according to media reports.

U.S. Secretary of State Marco Rubio said Washington could achieve its objectives without deploying ground troops but noted that forces were being positioned to give policymakers “maximum” flexibility.

Defense analysts cited in reports said limited operations could aim to secure maritime routes or seize key infrastructure such as Kharg Island, a major hub for Iran’s oil exports.

Military experts have cautioned that even limited ground incursions could lead to prolonged engagement, raising the risk of a broader conflict and increased casualties.

Concerns also persist over the economic implications of instability around the Strait of Hormuz, through which a significant share of global energy supplies passes.

No final decision on ground operations has been announced, and U.S. officials have not publicly confirmed the scope or timing of any potential action.

The report, citing Department of Defense officials, said the proposed deployment could include infantry units and armored assets, reflecting a broader effort to reinforce the U.S. posture in a region already on heightened alert amid the ongoing Iran conflic.

The potential troop increase would add to a growing U.S. presence in the region. The Pentagon is preparing to send at least 1,000 soldiers from the Army’s 82nd Airborne Division, according to earlier reporting by the Associated Press.

This would come alongside approximately 5,000 Marines being repositioned to the Middle East, on top of an existing force of around 50,000 U.S. personnel.The incremental buildup has fueled speculation that Washington is positioning itself for possible limited ground operations tied to strategic objectives linked to Iran’s energy infrastructure and regional waterways.

Analysts say U.S. ground forces could be capable of securing key maritime chokepoints or energy facilities, but warn of the potential for a prolonged and costly engagement. Mick Mulroy, a former deputy assistant secretary of defense, said that while such operations are feasible, the broader question remains whether they are strategically justified.

He noted that diplomacy remains the preferred pathway, though its success depends on both sides demonstrating willingness to compromise.

Trump said on Thursday that Iran had allowed several Pakistan-flagged oil tankers to transit a key maritime route, describing the move as a possible positive signal in the context of ongoing tensions.

The administration continues to balance military preparedness with diplomatic outreach, as indirect contacts between Washington and Tehran raise the prospect of negotiations even as force levels in the region expand.
