On Friday, a U.S. fighter jet carried out precision strikes that disabled two Iran-flagged oil tankers in the Gulf of Oman, an action Washington framed as enforcement of an ongoing port blockade. The targeted attack immediately triggered Iranian retaliatory strikes and sent shockwaves through a tenuous regional ceasefire, arriving at a critical moment when Tehran was actively reviewing a new U.S. diplomatic proposal to end the 10-week-old Middle East conflict.
The confrontation unfolded in a strategically vital waterway that acts as the primary gateway to the Strait of Hormuz, the chokepoint through which roughly a fifth of global oil supplies pass daily. U.S. Central Command confirmed that an F/A-18 Super Hornet used precision munitions to disable the two vessels, stating the action was intended to stop the ships from reaching Iranian territorial waters. In the immediate aftermath, an anonymous senior Iranian military official told local media outlets that the country’s naval forces had launched proportional retaliatory strikes against what it labeled “American terrorism and ceasefire violation,” adding that active clashes had ceased following the exchange.
This latest flare-up came less than 24 hours after smaller-scale skirmishes in the strait, a waterway that a top adviser to Iran’s Supreme Leader has compared to holding “an atomic bomb” due to its outsized geopolitical importance. U.S. Secretary of State Marco Rubio, speaking to reporters during a diplomatic stop in Rome, repeated longstanding U.S. policy that Iranian control of the critical oil transit route is “unacceptable.” Rubio also confirmed that Washington was awaiting Tehran’s formal response to its latest peace proposal, shared via Pakistani intermediaries, and expressed cautious hope that the proposal would receive serious consideration from Iranian leadership.
The proposal put forward by the U.S. would extend the current fragile Gulf ceasefire to create space for comprehensive negotiations aimed at reaching a permanent end to the conflict. The conflict began 10 weeks ago when U.S. and Israeli forces launched joint strikes against Iranian military and nuclear targets across Iran. Iranian Foreign Ministry spokesman Esmaeil Baqaei told Iran’s official ISNA news agency on Friday that the U.S. proposal remains “under review” by Iranian authorities, with no final decision yet issued.
In the hours following the tanker strikes, Iranian officials ramped up diplomatic pushback against the U.S. action. Iran’s United Nations Ambassador Amir Saeed Irvani sent an official letter to U.N. Secretary-General and the Security Council accusing Washington of a deliberate violation of the existing ceasefire that undermines all ongoing diplomatic efforts to de-escalate. Iranian Foreign Minister Sayed Abbas Araghchi, in a phone call with his Turkish counterpart, voiced deep skepticism about the U.S.’s commitment to a diplomatic resolution of the conflict, according to Iran’s Tasnim news agency.
Parallel diplomatic efforts were underway in Washington Friday, where Qatari Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani held talks with U.S. Vice President JD Vance focused on supporting the Pakistani-brokered peace initiative. Qatar has found itself drawn into the conflict already: Iran has repeatedly targeted Qatari sites throughout the war, in retaliation for Qatar hosting a large forward-deployed U.S. air base on its territory.
In a separate development that adds further uncertainty to global energy markets, satellite imagery analyzed by global monitoring firm Orbital EOS shows a growing oil slick spreading off the west coast of Iran’s Kharg Island, the country’s primary oil export terminal. The slick currently covers more than 20 square miles (52 square kilometers), though the exact cause of the spill remains unconfirmed as of Friday. Kharg Island is the linchpin of Iran’s oil export industry, which forms the backbone of the country’s already severely battered economy, and sits just north of the Strait of Hormuz in the Gulf.
The current crisis traces back to the outbreak of war on February 28, when Iran responded to the U.S.-Israeli strikes by effectively closing the Strait of Hormuz to commercial shipping. That closure sent global oil markets into turmoil and pushed crude prices sharply higher, prompting the U.S. to impose a full blockade of Iranian ports in response. Earlier last week, former President Donald Trump, whose administration launched the current military campaign, announced a large-scale U.S. naval operation to reopen the strait, only to reverse course just two days later and pivot back to diplomatic negotiations. The reversal came after Saudi Arabia, a key regional U.S. ally, publicly refused to grant U.S. forces access to Saudi bases and airspace for the planned operation. Senior Saudi sources told AFP Friday that Riyadh made the call because it believed the military operation would only escalate regional tensions and would not succeed in achieving its stated goals.
Beyond the Gulf, the separate parallel ceasefire between Israel and Iran-backed Hezbollah in Lebanon is also crumbling under mounting pressure. Friday saw Hezbollah launch two waves of attacks against Israeli military targets: first a salvo of missiles targeting an Israeli military base south of the coastal city of Nahariya, followed hours later by a swarm of attack drones targeting a second base in northern Israel. The group said the attacks were retaliation for a recent Israeli strike on Beirut’s southern suburbs and ongoing daily Israeli strikes across southern Lebanon.
Israel has continued its airstrikes against Hezbollah positions despite the formal ceasefire, and on Wednesday carried out its first attack on Beirut’s southern suburbs in a month, stating the strike killed a senior Hezbollah commander. Lebanon’s Ministry of Public Health reported Friday that 11 people were killed in Israeli strikes across southern Lebanon that day: 10 civilians, including two children and three women, plus one civil defense volunteer.
The new round of violence on the Lebanon front comes just days before Lebanon and Israel are scheduled to hold the first round of direct peace negotiations in Washington next week, a meeting that Hezbollah has issued repeated and vehement statements opposing. The two countries have remained officially in a state of war since 1948, making any diplomatic breakthrough a historic shift for the region.
