What Happened
- The Indian Coast Guard intercepted three oil tankers approximately 100 nautical miles west of Mumbai on February 6-7, 2026, as part of an operation targeting an international oil-smuggling syndicate.
- The three vessels seized are: AL JAFZIA, ASPHALT STAR, and STELLAR RUBY — all on the US Treasury's OFAC (Office of Foreign Assets Control) Iran sanctions list.
- STELLAR RUBY was operating under the Iranian flag; the other vessels used complex overseas-based corporate structures to obscure their Iranian links.
- The vessels are linked to a network associated with sanctioned Indian national Jugwinder Singh Brar, who owns a fleet of approximately 30 vessels operating in the Iran-linked shadow fleet.
- The syndicate used mid-sea ship-to-ship transfers in international waters to move cheap Iranian crude, evading customs duties and sanctions — a classic "shadow fleet" methodology.
- India tightened maritime surveillance across the Arabian Sea following the seizure, expanding Coast Guard patrol patterns.
Static Topic Bridges
Iran's Shadow Fleet and International Sanctions Architecture
A "shadow fleet" refers to a network of tankers that operate outside conventional shipping norms — using obscured ownership structures, frequent flag changes, AIS (Automatic Identification System) manipulation, and mid-sea ship-to-ship transfers — to smuggle sanctioned oil. Iran operates one of the world's largest shadow fleets to evade US-led sanctions imposed since 2018 under OFAC's Iran Transactions and Sanctions Regulations (ITSR).
- Approximately 430 tankers are currently engaged in carrying Iranian crude; of these, ~62% are falsely flagged and ~87% are under some form of US sanctions.
- OFAC (Office of Foreign Assets Control), under the US Treasury, administers and enforces economic and trade sanctions.
- Sanctioned entities are placed on the Specially Designated Nationals (SDN) list — any person/entity that deals with SDN-listed vessels risks secondary sanctions.
- Shadow fleet tankers frequently change names, IMO numbers (though IMO numbers are permanent vessel identifiers), and flag states.
- Sanctioned Iranian oil is sold at a 10-15% discount; buyers include refineries in China, India, and some Asian states.
- In 2025, OFAC sanctioned over 875 persons, vessels, and aircraft as part of the Iran sanctions campaign.
Connection to this news: The three seized tankers' IMO numbers matched OFAC SDN-listed vessels, enabling India's Coast Guard to act on pre-existing intelligence — a model of coordinated international sanctions enforcement.
Indian Coast Guard: Mandate, Powers, and Jurisdiction
The Indian Coast Guard (ICG) was established by the Coast Guard Act, 1978 and operates under the Ministry of Defence. Its jurisdiction extends over India's Exclusive Economic Zone (EEZ) — 200 nautical miles from the baseline — and the contiguous zone (24 nautical miles). The ICG enforces fisheries laws, prevents smuggling, conducts search and rescue, and maintains maritime law in areas where the Indian Navy does not operate.
- India's EEZ covers approximately 2.37 million square kilometres — one of the largest in the Indian Ocean Region.
- Under UNCLOS (UN Convention on the Law of the Sea, 1982), a coastal state has sovereign rights over the EEZ for resource exploitation and jurisdiction over customs, fiscal, immigration, and sanitation laws in the contiguous zone.
- Beyond 200 nautical miles (high seas), universal jurisdiction applies for piracy under UNCLOS Article 105.
- The interception at ~100 nautical miles west of Mumbai was clearly within India's EEZ, giving ICG full legal authority to board and seize.
- The ICG coordinates with the Navy, Customs, DRI (Directorate of Revenue Intelligence), and MEA for cross-agency maritime security operations.
Connection to this news: The seizure at 100 nautical miles west of Mumbai was well within India's EEZ — ICG acted under both domestic law (Customs Act, COFEPOSA) and international maritime law frameworks to detain the vessels.
Proliferation Security Initiative (PSI) and Maritime Interdiction
The Proliferation Security Initiative (PSI), launched in 2003 by the US, is a voluntary framework through which 116 nations cooperate to interdict shipments of weapons of mass destruction and related materials. India joined PSI in 2008. Beyond PSI, the UNSC has authorised targeted sanctions against Iran under multiple resolutions, and bilateral intelligence sharing between the US and India on shadow fleet movements has intensified under the US-India Major Defence Partnership.
- PSI allows participating states to conduct joint exercises, share intelligence, and coordinate interdiction at sea and in port.
- UNCLOS Article 110 (Right of Visit) permits warships to board foreign-flagged vessels on the high seas only in specific circumstances: piracy, slave trade, unauthorised broadcasting, statelessness, or same nationality as the warship.
- Ships without nationality (stateless vessels) may be boarded on the high seas by any state's naval forces.
- Bilateral US-India defence cooperation includes the GSOMIA (General Security of Military Information Agreement), LEMOA (Logistics Exchange Memorandum of Agreement), and COMCASA — frameworks enabling intelligence and logistics sharing relevant to maritime interdiction.
Connection to this news: India's seizure of OFAC-listed vessels signals alignment with US-led sanctions enforcement architecture, positioning India as an active partner in preventing illicit Iranian oil trade — a significant departure from India's earlier posture of importing Iranian oil under rupee-payment arrangements.
Key Facts & Data
- Three tankers seized: AL JAFZIA, ASPHALT STAR, STELLAR RUBY — all on US OFAC SDN list.
- Interception point: ~100 nautical miles west of Mumbai (within India's Exclusive Economic Zone).
- STELLAR RUBY was flying the Iranian flag at time of interception.
- Network linked to Jugwinder Singh Brar — an Indian national operating a ~30-vessel Iran-linked shadow fleet.
- Deceptive method: mid-sea ship-to-ship transfers in international waters to obscure oil origin.
- OFAC sanctioned 875+ persons, vessels, and aircraft in its Iran campaign in 2025.
- Of ~430 tankers carrying Iranian crude: ~62% falsely flagged, ~87% under sanctions.
- India's EEZ: 2.37 million sq km; contiguous zone: up to 24 nautical miles from baseline.
- ICG established under Coast Guard Act, 1978; operates under Ministry of Defence.
- India joined PSI (Proliferation Security Initiative) in 2008.
- India imports significant Iranian crude via rupee-payment arrangements when relations permit — this seizure signals a policy recalibration.
