Background

Shamkhani himself was killed on 28 February 2026 in the opening US-Israeli strikes, confirmed by Iranian state television and Al Jazeera alongside the deaths of Defence Minister Nasirzadeh and IRGC commander Pakpour. An Arab Iranian from Khuzestan, he served as secretary of the Supreme National Security Council from 2013 to 2023, a tenure spanning nuclear negotiations, the 2023 Saudi-Iran normalisation, and coordination of the proxy network across Iraq, Syria, Lebanon and Yemen. He previously served as Defence Minister and Navy commander, spending his career bridging IRGC culture and civilian diplomatic channels — one of the few figures trusted across factional lines. His elimination removed the interlocutor whose back-channels had sustained Iranian diplomacy at the moment Masoud Pezeshkian's government most needed one.

Six weeks after his death, Ali Shamkhani's name became the legal anchor of the first OFAC action to reach inside Indian municipal jurisdiction since the 2026 Iran war began. On 15 April 2026 the US Treasury's Office of Foreign Assets Control published designations under the Iran-EO13902 and SDGT programmes naming two Indian nationals (Chetan Prakash Balhotra, Tanjore Sunilkumar Srinivas), three companies including Fleet Tanqo Private Limited of Navi Mumbai and House of Shipping Private Limited of Chennai, and added nine tankers to the SDN list. Treasury titled the action "Economic Fury Targets Illicit Oil Smuggling Network Run by Iranian Regime Elite" and identified Shamkhani's network as the structure it was dismantling. The IRGC fired on Indian-flagged tankers Sanmar Herald and Jag Arnav three days later.

India's Ministry of External Affairs maintained public silence for nine days on the designations. The exposure compounded on 26 April 2026 when India's Chabahar port sanctions waiver lapsed with no signed renewal, adding a second layer of secondary-sanctions risk on Indian counterparties in the same week. The Shamkhani sanctions architecture will continue to tie Indian refiners, UAE free-zone companies and Gulf clearing banks to secondary-sanctions risk for as long as Treasury keeps the designations live, regardless of who now operates the shipping — a demonstration that US enforcement networks outlive the named Iranian principals targeted in the February decapitation strikes.
