The United States military said it began strikes on Iran on Saturday after the Islamic Revolutionary Guard Corps attacked a Cyprus‑flagged container ship in the Strait of Hormuz, leaving a crew member missing and causing fire and engine damage.

Iran announced that the strait was closed again, while the United Kingdom warned of an incident east of Oman involving a damaged container ship.

The attack occurred amid heightened tensions between the United States and Iran, which have exchanged threats and diplomatic overtures since agreeing to a limited cease‑fire three weeks earlier. President Donald Trump had warned that Iran faced a large missile response if it attempted to assassinate him and said a cease‑fire was no longer in effect, though he noted that Iran had requested to resume talks.

U.S. Central Command said the strikes were the third round this week targeting IRGC forces responsible for the attack on M/V GFS Galaxy. A civilian crew member was reported missing and a fire and significant engine room damage hampered the vessel’s transit.

The United Kingdom’s Maritime Trade Operations Center reported a separate incident nine nautical miles east of Oman, where a container ship sustained rear damage, a fire broke out, though the vessel and cause were not identified.

Senior U.S. officials said Iran had described prior attacks as the work of a rogue IRGC unit and expected Iran to issue a statement confirming the strait was open and that its forces would cease shooting at ships.

In a statement carried by state media, the IRGC said the strait was closed until further notice, accusing the United States of interference and saying the United States was imposing a heavy cost by degrading Iran’s ability to attack civilian mariners.

The strikes follow earlier U.S. and Israeli actions in late February that killed Ayatollah Ali Khamenei, according to the source; Mojtaba Khamenei, the successor, vowed to avenge the killing.

Iranian foreign minister met Oman’s foreign minister in Muscat for talks on the strait; Oman said both sides agreed to continue technical and political discussions to reach agreements consistent with international law.

The latest exchange has renewed uncertainty over the future of the limited peace accord, as diplomatic channels remain open but the status of maritime traffic in the Strait of Hormuz remains unresolved.
