Tehran summons Ukrainian envoy over the attack, which it says killed one sailor and wounded another.

Tehran has accused Ukraine of attacking an Iranian commercial vessel in the Caspian Sea, causing an explosion that killed one sailor and injured another.

Iran’s Ministry of Foreign Affairs summoned Ukraine’s chargé d’affaires in Tehran to protest what it described as a “hostile and criminal” attack on Saturday, state news agency IRNA reported.

The ministry claimed the attack had been acknowledged by the Ukrainian leadership and said it reflected Kyiv’s continued “irrational and hostile approach” towards Iran. It warned Iran would defend its national interests.

It also described the incident as a violation of Article 2(4) of the United Nations Charter and said it could further inflame and expand the Russia-Ukraine war.

Iranian Foreign Minister Abbas Araghchi also discussed the matter in a phone call with the European Union’s High Representative for Foreign Affairs Kaja Kallas, his office said in a statement.

Araghchi strongly condemned Ukraine’s military attack on the vessel in the Caspian Sea, and reportedly “called for a firm response from the United Nations Security Council, the European Union, and the international community, and for the perpetrators and supporters of this criminal act to be held accountable”, according to the statement shared on Telegram.

‘Pressure’

“The Iranians are not really happy with [the attack], while they’re also dealing with a US blockade on the southern coast,” said Al Jazeera’s Tohid Asadi, reporting from Tehran.

He explained that the attacks on Iran’s northern coast are “putting extra pressure” on Iran’s maritime trade.

In its condemnation, Iran’s Foreign Ministry reiterated that Tehran has never intervened in the Russia-Ukraine conflict.

The incident came as Ukrainian President Volodymyr Zelenskyy announced in a post on X that Kyiv had achieved “very strong results” with long-range strikes in the Caspian Sea, hitting “vessels used in military cargo shipments involving Iran, as well as a warship.” He did not identify the commercial vessel named by Tehran as a target.

Zelenskyy separately alleged that Russia had been passing satellite imagery of Gulf states and US military sites to Iran. He said surveillance on July 19 and 20 covered airbases in Bahrain, Jordan and Kuwait.

Iran and Ukraine have been at odds since 2022, when Iran sold Russia the Shahed drones that Moscow has since adapted and launched in their thousands at Ukrainian cities.

Kyiv says it has shot down more than 44,000 of the Iranian-designed drones since Russia’s invasion.

Ukraine has also offered its drone interceptors and expertise to governments in the Gulf that have come under Iranian attack during the US-Iran war, deploying anti-drone specialists to Qatar, the United Arab Emirates, Saudi Arabia and Kuwait.
