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 ᴀssistance, which has not been previously reported, signals that the rapidly expanding conflict now features one of America’s chief nuclear-armed compeтιтors with exquisite intelligence capabilities.

Since the war began Saturday, Russia has pᴀssed Iran the locations of U.S. military ᴀssets, including warships and aircraft, said the three officials, who spoke on the condition of anonymity because of the matter’s sensitivity.

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 ᴀssistance 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.
