In brief
Iran’s Islamic Revolutionary Guard Corps (IRGC) announced on Wednesday that four oil tankers attempting a forbidden southern route through the Strait of Hormuz hit naval mines and exploded, setting the vessels on fire. The same day, the IRGC said it shot down a U.S. MQ‑9 Reaper drone and warned of a “final blow” against Israel and the United States. The statement follows the IRGC’s tightening of control over the strait since Feb. 28, following joint U.S.–Israeli strikes on Iran.
Iran’s Islamic Revolutionary Guard Corps (IRGC) said on Wednesday that four oil tankers seeking to cross the Strait of Hormuz via a prohibited southern route detonated after striking naval mines, setting the vessels ablaze and disrupting maritime traffic. The statement was published on the IRGC’s official news outlet, Sepah News.
According to the IRGC’s report, the explosions were caused by the mines, which are located in the southern part of the waterway. The statement added that two other ships, also attempting to cross the strait, were stopped by IRGC forces. The June 04 report therefore records both the violent detonation of the four tankers and the halting of additional vessels.
The same article noted that earlier on Wednesday, the IRGC’s air defence forces shot down an MQ‑9 Reaper drone over the Strait of Hormuz at 4:30 a.m. local time (0100 GMT). The drone was identified as a U.S. low‑cost uncrewed combat attack system, and the IRGC confirmed that it had been intercepted by its air defence forces in recent months.
In a separate event on Tuesday, the IRGC said that two U.S. low‑cost uncrewed combat attack system drones had been struck over the southern Iranian port city of Bandar‑e Khamir, implying an ongoing military engagement between the parties.
The IRGC warned that its forces were prepared to deliver a “final blow” to Israel and the United States, indicating a potentially escalatory stance toward the two countries. This statement was made by the IRGC’s spokesperson on the same news platform, Sepah News.
Earlier, on Feb. 28, the IRGC tightened its grip on the Strait of Hormuz, barring safe passage for vessels belonging to or affiliated with Israel and the United States. That move followed joint U.S.–Israeli strikes on Iran, prompting the IRGC to position forces along the southern interface of the waterway to prevent further incursions.
The report reiterates the IRGC’s claim that the four tankers were “violating” the prohibited route. This term was used by the IRGC to denote the vessels’ attempt to traverse the forbidden corridor. By marking the vessels as violators, the IRGC explicitly positions the incident as a breach of its maritime security protocols.
In addition to the attacks on maritime vessels, the IRGC’s description of its successes against U.S. and Israeli drones demonstrates a pattern of active defence operations in the region. The stated laser‑pointing at the drones and the claim of a “final blow” highlight the continuing threat the IRGC believes it must confront from Western actors.
The Reuters‑style coverage of these events is confined to the IRGC’s statements on Sepah News. Since the announcement, there have been no independent corroborations from foreign shipping or other agencies. Consequently, the record of the incident remains limited to the IRGC’s public reporting.
As the IRGC continues to assert its control over the Southern Strait of Hormuz and its military deterrence stance, the ripple effects will extend to shipping lanes and diplomatic relations with the United States and Israel. While the IRGC claims a decisive action against the four vessels, the ongoing drone interceptions highlight an elevated security posture in the area. The international implications of these events will be closely monitored by nations dependent on the Strait’s maritime traffic.
