APAC Brief: Iran Fires on Indian Ships in Hormuz — India Summons Ambassador as Strait Closes Again
Two Indian-flagged ships (Sanmar Herald, Jag Arnav) fired upon by IRGC gunboats in Hormuz. India summons Iran's ambassador. Supertanker carrying 2M barrels of Iraqi oil among vessels targeted. Iran closes strait again just 24 hours after declaring it open.
Day 51. The attack made it personal for Asia. Iran's IRGC fired on two Indian-flagged ships in the Strait of Hormuz — the Sanmar Herald and Jag Arnav — including a supertanker carrying 2 million barrels of Iraqi oil. India summoned Iran's ambassador within hours. And the IRGC shut the strait again, just 24 hours after Iran's foreign minister had declared it "completely open." The single worst day for Asian shipping of the entire crisis.

Indian ships fired upon
Indian Foreign Secretary Vikram Misri summoned Iran's Ambassador Mohammad Fathali on Saturday evening, expressing "deep concern" over the firing on two India-flagged merchant vessels in the Strait of Hormuz. The Sanmar Herald — a supertanker with 2 million barrels of Iraqi oil aboard — was among those attacked, despite reportedly having received Iranian clearance to transit. The Jag Arnav was also targeted. No casualties reported. This is the first time during the crisis that Iran has attacked ships of a major Asian country not aligned with the US or Israel — a dangerous escalation that shatters the thin trust that had kept Asian shipping trickling through.
The 24-hour reversal
Friday morning: Iran's Foreign Minister Araghchi declared Hormuz "completely open." Saturday afternoon: the IRGC declared it closed again, citing the continued US blockade. "Approaching the Strait of Hormuz will be considered cooperation with the enemy," the IRGC warned. The whiplash reveals the power struggle inside Iran — Araghchi's diplomatic signals were overruled by the security establishment within hours. For Asian importers who had begun repositioning tankers, it's a devastating lesson.
What actually moved
Before the IRGC's closure announcement, 35 vessels transited Hormuz on Saturday — 8 inbound and 27 outbound, per Windward Daily Intelligence tracking data. More than a dozen tankers, including three sanctioned vessels, passed through after Friday's opening — before restrictions returned. Malaysia-linked vessels including the Ocean Thunder, loaded with Iraqi crude, are among the ships still expected to discharge cargo in Asia in coming days. China-flagged VLCCs Cospearl Lake and He Rong Hai had exited earlier in the month. But the main flow has stopped.
India's position tightens
India has been one of the most complex players in this crisis. During the opening weeks, India ran Operation Sankalp — Indian Navy escorts for LPG carriers through the Gulf of Oman. Two Indian-flagged gas carriers had been allowed to pass earlier. The country has ramped up emergency LPG measures and PNG rollouts. Now, Iran firing on Indian-flagged vessels pushes New Delhi toward a harder posture. Expect accelerated coordination with the Macron-Starmer defensive Hormuz initiative — India can no longer rely on bilateral arrangements with Tehran.
Australia, wider Asia
Australia has secured an extra 100 million litres of diesel through bilateral deals. PM Albanese called the reopening "fragile" even before the IRGC's reclosure — his caution now looks prescient. Around 50 tankers were reportedly en route to Australia. Mining and transport sector layoffs continue. Across Southeast Asia, the Philippines remains under a state of emergency. Vietnam, Bangladesh, and Pakistan continue to face severe fuel shortages.
What to watch
Whether Monday's Islamabad talks actually happen. India's response beyond summoning the ambassador — could Delhi move toward contributing to the defensive maritime mission? The ceasefire expires Wednesday, April 22. Australia's fuel reserves and the 50 tankers en route. And whether the Sanmar Herald incident becomes a flashpoint or a footnote in an already overflowing crisis.
