Iran’s Intensified Assault on Shipping in the Strait of Hormuz
By Drooid · · How we work
Surge in Attacks
In October, a record wave of assaults hit commercial vessels transiting the Strait of Hormuz. UKMTO data show 12 vessels were attacked between 5 and 11 October, the largest weekly tally since the U.S.–Israel war with Iran began on 28 February. By month-end, 26 vessels had been struck, including the Singapore-flagged GFS Pride, which sank after a projectile impact, and the Antigua-and-Barbuda-flagged Cape Dao, which sank on 23 September. Iranian-linked footage claims the ships were on “unauthorised routes,” while other sources describe the weapons as drones or projectiles.
Background & Context
Iran’s campaign follows its February 28 decision to close the strait after the U.S.–Israel offensive. The IRGC has warned that vessels taking “unauthorised” passages will be targeted. The United States has responded with escorted “dark” transits—nighttime passages in which tankers turn off transponders—to sustain oil flows. Attacks have also been reported north of Qatar on 8 October and near the UAE town of Al-Jazirah al-Hamra on 9 October.
Data & Statistics
- Oil throughput: 12.6 million barrels per day (bpd) on 13 October, down from 15 million bpd at the end of September (Kpler).
- Low point: 2.9 million bpd on 11 October, the month’s lowest figure (Kpler).
- Assault count: 10 tankers hit between 28 September and 4 October, another on 5 October (Kpler); 15 additional attacks recorded between 6 and 14 October (UKMTO).
Official Statements & Responses
The IRGC’s navy reiterated that vessels on “illegal and dangerous routes” will be struck, describing the GFS Pride incident as a mine explosion. CENTCOM countered that Iranian mines have been cleared and recent strikes were caused by projectiles, not mines. The United Kingdom’s Maritime Trade Operations continues to publish incident timelines but notes gaps because many vessels refuse to report attacks.
Criticism & Opposition
Deputy foreign minister Rayed Krimly of Saudi Arabia accused Iran of “encouraging” the Houthis’ escalation against Saudi targets, linking Tehran’s support to broader regional instability.
Conflicting Reports & Gaps
- Cause of sinkings: Iranian state media claim the GFS Pride hit a naval mine, while analysts and UKMTO reports attribute the loss to a drone or projectile strike. CENTCOM’s assessment aligns with the latter view.
- Attack tallies: BBC Verify cites 12 attacks between 5 and 11 October, whereas Al Jazeera’s week-ending 16 October summary also records 12 attacks but notes many incidents go unreported.
Verbatim Quotes
- “IRGC’s navy commander has no navy. American forces and regional partners clearly control the Strait of Hormuz,” — CENTCOM
- “Transits through the Strait of Hormuz continue despite Iran’s unwarranted aggression,” — Capt. Tim Hawkins, U.S. Central Command
What’s Next
The United States and Iran are positioning for influence ahead of the 3 November U.S. midterm elections, a date cited by multiple outlets as a potential catalyst for further escalation. U.S. officials say forces remain “prepared for larger attacks” after the elections, while Iran’s IRGC has announced a “new deployment formation” across the region. No formal cease-fire or negotiation timetable has been announced.
