Ukraine strikes Iranian cargo ship in Caspian Sea, directly linking two wars

Ukraine's attack on an Iranian commercial vessel in the Caspian Sea represents the first direct connection between the wars in Ukraine and Iran, according to reports.

Details of the July 25 Incident

While specifics remain unclear, Ukraine's intelligence agency, the SBU, stated that its drones struck an oil platform in the Caspian Sea, along with a Russian missile boat and "cargo ships that are under international sanctions."

President Volodymyr Zelensky announced on Saturday that Ukrainian forces had achieved "very good results" in long-range strikes in the Caspian Sea, including against vessels used to transport military cargo linked to Iran.

The BBC reported that Ukraine's ambassador to Israel, Yevgen Korniychuk, said the vessel had been carrying components for drones and missiles from Iran to Russia—not civilian cargo. Speaking to Israel's N12, he insisted that Ukraine and Israel were confronting the same "axis of evil" on different fronts.

Iranian Reaction

Iranian officials reacted angrily to the attack, reporting one sailor killed and vowing retaliation. According to Radio Free Europe, Ukraine's top diplomat in Iran was summoned to the Foreign Ministry in protest.

"Zelenskyy has attacked an Iranian commercial vessel, killing a sailor," Iranian Foreign Minister Abbas Araqchi said in a post on X, calling it "a blatant United Nations Charter violation done at Israel's behest to drag Europe into its war."

Ebrahim Azizi, who heads the national security committee in Iran's parliament, posted that Kyiv will soon learn that Tehran "leaves no action unanswered."

The Kremlin also weighed in, with spokesman Dmitry Peskov telling reporters that the Ukrainian attack should be seen as an attack on Iran itself.

Russia-Iran Military Ties

Iran and Russia have developed a close military relationship. The two U.S. adversaries conducted joint naval exercises off southern Iran on February 19.

The BBC notes that Iran began supplying Russia with its Shahed drones in 2022, when the war between Russia and Ukraine began. Moscow has since modified the drones and used them to hit Ukrainian cities.

Zelensky told Sky News over the weekend that Tehran was planning to send ballistic missiles to Russia for use in the war. The report suggested that short-range missiles were being supplied from 2024.

Previous Ukrainian Strikes in the Caspian Sea

This is not the first time Ukraine has hit targets in the Caspian Sea, which forms a strategically vital supply route between Russia and Iran.

The BBC reported that Ukraine has been relentlessly targeting Russia's shadow fleet of oil tankers, seeking to choke off a major source of revenue for the Kremlin.

Radio Free Europe stated that at least 12 Russian warships have been struck over the course of the Russian invasion, adding that Israel has hit Iranian targets on the Caspian in conjunction with U.S. forces. On March 18, about three weeks after the start of the U.S.-Israeli campaign, Israeli jets hit the port of Bandar Anzali, sinking an unknown number of naval ships.

Experts said it was possible Ukrainian forces acted this weekend with the help of Israeli intelligence.

Wider Implications

Ukraine is dismissing Iran's threat of retaliation. Foreign Minister Andrii Sybiha posted on X: "The regime in Tehran is a direct accomplice to Russian aggression against Ukraine, fuelling Moscow's criminal war with weapons that have killed Ukrainians since 2022."

Sybiha also accused Iran of trying to shift attention away from Russia's attacks on ships carrying grain from Ukrainian ports, which he said were threatening global food security, via the BBC.

The Kyiv Post reported Zelensky saying: "We must be careful. We must do everything to ensure that under no circumstances do we open a new front, but we must be honest. The Iranians and the North Koreans have already attacked us."

Zelensky said he hoped the two countries would not expand their involvement but warned that Ukraine must prepare for any development. "We have to be ready for everything. Just be ready and understand that we cannot trust these people."

The president noted that both countries had supplied Russia with weapons without any preceding Ukrainian escalation against them. "At the very beginning, without any statements or any escalation on our part, the Iranians provided weapons, the North Koreans provided weapons – drones, missiles and 155mm artillery shells," Zelensky said.

Potential Iranian Retaliation

Experts cited by Radio Free Europe said it is unclear what Iran could do to retaliate.

"Tehran is clearly angry, but it has very limited ability to project military power against Ukraine," said Saeid Golkar, an expert on Iran's military and a professor at the University of Tennessee at Chattanooga. "If it decides to respond, I'd expect something indirect such as cyber operations, intelligence activity, support for Russian operations, or possibly targeting Ukrainian interests abroad rather than a conventional military strike."
