The United States and Iran exchanged military strikes on maritime targets on Saturday, September 5, 2026, amid a flare-up in a conflict that began in February. U.S. Central Command (CENTCOM) reported that it destroyed three Iranian oil tankers in retaliation for ballistic missiles launched by the Islamic Revolutionary Guard Corps (IRGC) at two U.S. Navy vessels, including an aircraft carrier and a guided-missile destroyer. The maritime engagements occurred near Kharg Island and in the Gulf of Oman, with one tanker crew forced to abandon ship after multiple hits. Both sides reported no casualties from these specific incidents.
Tensions rose last week after a suspected U.S. strike hit a wedding celebration in Iran, which Iranian officials said killed at least five people and injured dozens. Washington stated it is investigating the claim. Iran responded with drone and missile attacks on U.S. military bases in the Gulf, leading to the latest exchange involving commercial and military shipping. Admiral Brad Cooper, head of CENTCOM, stated the strikes were intended to impose a "higher economic cost" on the IRGC. The IRGC responded by threatening intensified strikes against U.S. military vessels and later claimed it targeted tankers on "unauthorised routes" in the Strait of Hormuz.
This escalation has impacted global energy markets, with Brent Crude oil prices rising above $90 a barrel this week. According to the United Kingdom Maritime Trade Operations Center, vessel traffic through the Strait of Hormuz is at approximately 90% of pre-war levels. The U.S. aircraft carrier Abraham Lincoln, which carries roughly 5,000 personnel, set a modern record for consecutive days at sea during the conflict before departing Thailand on Sunday, September 6, following a five-day port visit. In the United Kingdom, Chancellor John Healey warned that the conflict is driving up government borrowing costs and inflation, noting that the upcoming October 28 budget would address these pressures.
In separate regional developments, the Israeli military reported striking southern Lebanon on Sunday, September 6, in response to Hezbollah drone attacks. Since March 2, Israeli strikes have reportedly killed more than 4,300 people in Lebanon. Additionally, Iranian state media reported a fuel tanker explosion in western Iran on Saturday that killed 11 people, which authorities attributed to a faulty brake system. President Donald Trump characterized the conflict with Iran as "small potatoes" during an Oval Office briefing on Friday, September 4, while Vice President JD Vance declined to label the situation a war.
