In brief
According to an IRGC statement on 4 November 2026, four oil tankers that were attempting to use the Rahim unit’s southern route in the Strait of Hormuz detonated after hitting naval mines, setting them ablaze. The Guards also said they had downed a U.S. MQ‑9 Reaper drone over the strait and warned of a potential ‘final blow’ against the United States and Israel. The incident follows Iran’s firmer control of the strait established on 28 February following a joint U.S.-Israeli attack on Iranian forces.
On 4 November 2026, Iran’s Islamic Revolutionary Guard Corps (IRGC) announced that four oil tankers, described as "violating," had detonated after striking naval mines while attempting to cross the Strait of Hormuz via the southern forbidden route. The explosions set the vessels ablaze, according to a statement released on the IRGC’s official news outlet, Sepah News. The statement also noted that two other ships were halted as they tried to pass through the strait.
In a separate operation conducted on the same day, 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, identified as the 56th MQ‑9 Reaper, was intercepted in what the Guard described as one of several recent successes against unmanned aerial vehicles. These air‑defence achievements are part of a broader campaign that Tuesday saw the air defence forces strike two U.S. low‑cost uncrewed combat attack system drones over the southern Iranian port city of Bandar‑e Khamir.
The IRGC’s statement warned that its forces were ready to deliver a "final blow" to the United States and Israel, following the tightening of Iranian control over the Hormuz Strait on 28 February. That month, Iran barred safe passage for vessels belonging to or affiliated with Israel and the United States after a joint U.S.-Israeli strike against Iranian forces, according to the Guard’s own reporting.
The incident reflects a continued escalation in tensions surrounding the crucial waterway that serves as a major conduit for global trade. While the Guard cited the miners and the subsequent detonations as a defensive act, no independent verification of the claims has yet been reported. The situation remains fluid, with the Guards’s statements suggesting readiness for further escalation should the perceived violations continue.
