IRGC attacks Singapore-flagged cargo ship near Strait of Hormuz, US officials say

The Islamic Revolutionary Guard Corps (IRGC) attacked a Singapore-flagged cargo vessel near the Strait of Hormuz, according to senior US officials cited by the Wall Street Journal. Damage was reported but no casualties. The strike tests the informal understanding between Washington and Tehran, after the IRGC earlier fired warning shots at vessels in the area.

Senior US officials told the Wall Street Journal that the Islamic Revolutionary Guard Corps (IRGC) attacked a Singapore-flagged cargo vessel near the Strait of Hormuz on Thursday evening. The vessel sustained damage but no casualties were reported, according to the sources.

The Zioneer has tracked this incident throughout the day. At 18:18 Jerusalem, the IRGC claimed it engaged a vessel 7.5 nautical miles off Oman for transiting an unauthorized route. Minutes later, US officials confirmed the target was a Singapore-flagged ship, and by 21:11 Jerusalem the report — first cited by a single US source — had been corroborated by two senior US officials, with the WSJ adding damage and casualty details. The attack followed IRGC threats to close the strait and warning shots fired at ships in the area earlier that day.

As The Zioneer has reported, the incident is the latest in a sequence of escalations around the Strait of Hormuz over the past several weeks, including IRGC claims of attacks on the US Fifth Fleet in Bahrain (June 10) and warning shots at US warships in the Gulf of Oman (June 5). The strike tests the informal understanding between Washington and Tehran that has governed tensions in the strategic waterway.

No independent confirmation has emerged from shipping sources, the IRGC, or the vessel's operator. The ship's identity, route, and the extent of damage remain unverified outside US official accounts.
