Iran was ready to strike Ukraine over Caspian Sea ship attack, says top advisor

Iran was prepared to launch strikes on three locations in Ukraine following what Tehran described as a Ukrainian attack on an Iranian merchant vessel in the Caspian Sea, a senior Iranian military official confirmed on 4 August. Mohsen Rezaei, a senior military advisor to Supreme Leader Mojtaba Khamenei, said Tehran had readied a retaliatory response but held back after Kyiv characterised the incident as accidental.
What Happened in the Caspian Sea
The incident, which occurred in the last week of July, involved an Iranian merchant ship carrying a cargo of iron. Tehran accused Ukrainian forces of striking the vessel, killing one crew member and injuring three others. Ukraine, for its part, said it had conducted drone attacks targeting two Russian ships carrying military material in the Caspian Sea, suggesting the Iranian vessel may have been struck in error.
Tensions Eased After Diplomatic Call
Retaliatory action was averted, at least temporarily, after a phone call between Iranian Foreign Minister Seyed Abbas Araghchi and his Ukrainian counterpart. Araghchi subsequently stated that Kyiv had assured Tehran the attack was unintentional. However, Rezaei made clear that an apology alone would not suffice. 'Even if it was a mistake, compensation is still expected,' he said.
Iran's Foreign Minister Blames Israel
On 26 July, Foreign Minister Araghchi went further, alleging that the attack was carried out at Israel's direction to draw Europe into the conflict. In a post on social media platform X, Araghchi wrote: '(Ukrainian President Volodymyr) Zelensky has attacked an Iranian commercial vessel, killing a sailor. A blatant UN Charter violation done at Israel's behest to drag Europe into its war. In calls with EU High Representative Kaja Kallas and Foreign Minister Sergey Lavrov, made clear that what the freeloader in Kyiv cannot go unanswered.'
Iran Presses the EU for Action
On 25 July, Araghchi called on the European Union to take 'decisive' action against Ukraine over the targeting of the Iranian vessel. He raised the issue directly in a phone call with EU Foreign Policy Chief Kaja Kallas, during which the two sides also discussed broader regional developments, according to a statement from the Iranian Foreign Ministry.
What This Means for the Wider Conflict
The episode marks a significant, if underreported, flashpoint in the broader Russia-Ukraine war — one that has now drawn Iran into a direct confrontation with Kyiv. Notably, Iran has been a key supplier of drones to Russia, making the Caspian incident a collision of two separate but intertwined conflicts. Whether Tehran's demand for compensation is met, and how Kyiv responds, will determine whether the diplomatic pause holds.
Point of View
Even if the action was ultimately suspended, signals a new threshold of assertiveness. The more revealing detail is Araghchi's public accusation that Israel orchestrated the attack to drag Europe in: that is not a diplomatic claim, it is an information-war move. Whether or not Kyiv pays compensation, Iran has used this episode to simultaneously pressure Ukraine, signal strength to its domestic audience, and frame Israel as the hidden hand — a triple play that serves Tehran's strategic narrative far more than any missile strike would have.
