West Asia war LIVE: U.S. launches strikes on Iran after attack on civilian vessel in Strait of Hormuz
United States forces carried out a fresh, third round of strikes on Iranian targets after Iranian forces attacked a Cyprus-flagged container vessel transiting the Strait of Hormuz, leaving a crew member missing and causing an onboard fire and engine-room damage.
The strikes hit sites in southern Iran, including Qeshm Island, Bandar Abbas, and Sirik, reportedly targeting missile and drone facilities, naval assets, ammunition storage, communication networks, and coastal surveillance infrastructure.
The U.S. military described the action as intended to "degrade Iran's ability to attack civilian mariners and commercial ships freely transiting the strait."
The strikes follow the breakdown of an earlier ceasefire between the United States and Iran, part of a wider conflict that began in early 2026 and has repeatedly disrupted shipping and closed the Strait of Hormuz at various points during the year.
The escalation renewed concerns over global oil and shipping disruptions, given the strait's role as one of the world's most heavily used maritime chokepoints.
Strait of Hormuz: Geography and Strategic Significance
The Strait of Hormuz is a narrow sea passage connecting the Persian Gulf to the Gulf of Oman and the wider Arabian Sea, lying between Iran to the north and Oman (the Musandam Peninsula) to the south. At its narrowest point it is only about 33-39 km wide; navigable shipping uses a traffic separation scheme with one inbound and one outbound lane, each roughly 3 km wide, separated by a buffer zone, largely within Omani territorial waters. It is the sole sea outlet for oil and gas exports from several Gulf states, making it one of the world's most critical maritime "chokepoints" alongside the Strait of Malacca, Bab-el-Mandeb, and the Suez Canal.
Key Details
- Connects the Persian Gulf to the Gulf of Oman/Arabian Sea; bordered by Iran and Oman.
- Narrowest width: roughly 33-39 km; shipping lanes about 3 km wide each way.
- Carries an estimated 20-25% of the world's seaborne oil trade and a significant share of global LNG trade (much of it from Qatar).
- Iran has not ratified UNCLOS, but the right of transit passage through straits used for international navigation (UNCLOS Part III) is claimed and generally respected by most maritime states, including the U.S. (also a non-ratifier).
The attack on a civilian vessel inside the strait, and the resulting U.S. strikes, illustrate why this chokepoint is treated as a global security flashpoint — any disruption here has outsized consequences for international energy markets and shipping insurance, well beyond the two states directly involved.
India's Energy Security Exposure and Naval Response (Operation Sankalp)
India imports the large majority of its crude oil and a very high share of its LPG via Gulf routes that pass through the Strait of Hormuz, though sustained diversification of crude sourcing (including to Russia, West Africa, and the U.S.) has reduced this dependence in recent years. To protect Indian-flagged merchant shipping in this corridor, the Indian Navy has maintained "Operation Sankalp" since June 2019 — a standing deployment that provides armed escort, surveillance, and rapid response to threats such as piracy, mines, and missile/drone attacks in the Gulf of Oman, Persian Gulf, and Gulf of Aden.
Key Details
- Operation Sankalp launched 19 June 2019 by the Indian Navy to safeguard Indian-flagged vessels in the Gulf region.
- India has repeatedly escorted and evacuated Indian-flagged vessels from the strait during the 2026 conflict using Operation Sankalp assets.
- A large share of India's LPG imports and a substantial (though declining) share of crude oil imports transit the strait.
Renewed strikes and attacks on commercial shipping in the strait directly threaten vessels of the kind India depends on for energy imports, which is why Operation Sankalp-type naval escort operations become operationally relevant each time tensions in the strait escalate, as with this latest round of strikes.
Legal Basis for Freedom of Navigation and Use of Force at Sea
International law distinguishes between the "innocent passage" regime (through territorial seas generally) and the stronger "transit passage" regime that applies specifically to straits used for international navigation, such as Hormuz, under UNCLOS. Transit passage cannot be suspended by the bordering states even during tension, unlike innocent passage, which coastal states may restrict in certain circumstances. Attacks on civilian/merchant vessels transiting such straits, and retaliatory military strikes by third states, raise separate questions under the UN Charter framework on the use of force (Article 2(4) prohibition, Article 51 self-defence) — questions that are contested and unresolved in the ongoing conflict.
Key Details
- UNCLOS (1982) Part III governs transit passage through international straits; it cannot be suspended by littoral states.
- UN Charter Article 2(4) generally prohibits the use of force against another state's territorial integrity; Article 51 preserves the right of individual/collective self-defence.
- Both Iran and the United States are non-ratifiers of UNCLOS but both invoke customary international law rights of passage.
The characterization of the strikes as a response "to attack on civilian vessel" is a direct invocation of the passage-and-self-defence framework — testable ground for how UPSC frames maritime law and use-of-force questions in the IR/security syllabus.
- Strait of Hormuz narrowest point: approximately 33-39 km; carries roughly 20-25% of world seaborne oil trade.
- U.S. strikes described as the third round in the current escalation, targeting sites at Qeshm Island, Bandar Abbas, and Sirik in southern Iran.
- Operation Sankalp (Indian Navy): active since 19 June 2019, focused on escort and protection of Indian-flagged shipping in the Gulf region.
- The strikes followed the breakdown of a prior US-Iran ceasefire arrangement reached earlier in 2026.
