Russia is providing Iran with targeting information to attack American forces in the Middle East, the first indication that another major U.S. adversary is participating — even indirectly — in the war, according to three officials familiar with the intelligence.
The assistance, which has not been previously reported, signals that the rapidly expanding conflict now features one of America’s chief nuclear-armed competitors with exquisite intelligence capabilities.
Since the war began Saturday, Russia has passed Iran the locations of U.S. military assets, including warships and aircraft, said the three officials, who spoke on the condition of anonymity because of the matter’s sensitivity.
“It does seem like it’s a pretty comprehensive effort,” one of the people said.
Reached by The Washington Post on Friday, Dmitry Peskov, the Kremlin spokesman, declined to comment on the intelligence findings. Moscow has called for an end to the war, which it labeled an “unprovoked act of armed aggression.”
The extent of Russia’s targeting assistance to Iran was not entirely clear. The Iranian military’s own ability to locate U.S. forces has been degraded less than a week into the fighting, the officials said.
Six U.S. troops were killed and several others were injured by an Iranian drone attack Sunday in Kuwait. Iran has fired thousands of one-way attack drones and hundreds of missiles at U.S. military positions, embassies and civilians, even as the joint American-Israeli campaign has hit more than 2,000 Iranian targets — including ballistic missile sites, naval assets, and the country’s leadership.
“The Iranian regime is being absolutely crushed,” said a White House spokeswoman, Anna Kelly, without commenting on any Russian aid to Iran. “Their ballistic missile retaliation is decreasing every day, their navy is being wiped out, their production capacity is being demolished, and proxies are hardly putting up a fight.”
The CIA and the Pentagon declined to comment.
When asked this week about his message to Russia and China, which are among Iran’s most powerful backers, Defense Secretary Pete Hegseth said that he didn’t have one and that “they’re not really a factor here.”
Two of the officials familiar with Russia’s support for Iran said that China did not appear to be aiding Iran’s defense, despite close ties between the two countries.
In a statement, the Chinese Embassy in Washington referred to Beijing’s diplomatic efforts to engage with partners in the region since the war began and said that the conflict should be “immediately ceased.”
Analysts said that the sharing of intelligence would fit the pattern of Iran’s strikes against U.S. forces, including command and control infrastructure, radars and temporary structures, like the one in Kuwait where six service members were killed.
Iran is “making very precise hits on early warning radars or over-the-horizon radars,” said Dara Massicot, an expert on the Russian military at the Carnegie Endowment for International Peace. “They’re doing this in a very targeted way. They’re going after command and control,” she added.
Iran possesses only a handful of military-grade satellites, and no satellite constellation of its own, which would make imagery provided by Russia’s much more advanced space capabilities highly valuable — particularly as the Kremlin has honed its own targeting after years of war in Ukraine, Massicot said.
Nicole Grajewski, who studies Iran’s cooperation with Russia at the Harvard Kennedy School’s Belfer Center, said that there had been a high level of “sophistication” in the Iranian retaliatory strikes, both in what Tehran has targeted and in its ability in some cases to overwhelm U.S. and allied defenses.
“They’re getting through air defenses,” she said, noting that the quality of Iran’s strikes appeared to have improved even from its 12-day war with Israel last summer.
The Pentagon is quickly burning through its supply of precision arms and air defense interceptors, people familiar with the matter have told the Post, underscoring concerns raised by Gen. Dan Caine, chairman of the Joint Chiefs of Staff, as President Donald Trump deliberated whether to approve the operation. The administration has sought to downplay Caine’s assessment.
Russia’s assistance reshuffles how various countries have engaged in a proxy war since Russia’s 2022 full-scale invasion of Ukraine. Throughout that conflict, U.S. adversaries including Iran, China and North Korea have provided Russia with either direct military aid or material support for Moscow’s vast defense industry. The United States has given Ukraine tens of billions of dollars’ worth of military equipment and shared intelligence on Russian positions to improve Kyiv’s targeting.
On Thursday, Ukrainian President Volodymyr Zelensky posted on X that the Trump administration had requested assistance in helping protect against Iranian drones and that Kyiv would provide “specialists” in response.
Iran has been one of Russia’s chief backers during the Ukraine war, sharing the technology to produce cheap one-way attack drones that have repeatedly been used to overwhelm Kyiv’s air defenses and exhaust Western stocks of interceptors donated to protect Ukrainian cities.
“The Russians are more than aware of the assistance that we’re giving the Ukrainians,” said one of the officials familiar with Moscow’s support for Tehran. “I think they were very happy to try to get some payback.”
The quality of Russia’s intelligence collection is not on a par with America’s but still ranks among the world’s best, this person continued.
The Post has previously reported that despite the blow to one of its closest partners, the Kremlin sees possible advantages in a prolonged war between the U.S. and Iran, including higher oil revenue and an acute crisis that distracts America and Europe from the war in Ukraine.
Iran, whose supreme leader was killed early in the conflict, could become the latest country to lose a pro-Russian government in recent years, following a Syrian uprising in late 2024 that ousted longtime dictator Bashar Assad and the U.S. military raid to seize Venezuelan President Nicolás Maduro in January.
Still, the lack of direct military involvement from Moscow is in part a sign of its need to focus elsewhere, Massicot said.
The Kremlin, she said, is “very much considering this is not their problem and not their war. From a strategic calculus perspective, Ukraine is still far and away the number one priority.”
