Russia has deepened its ties with the Islamic Republic since the start of the Ukraine war, and signed a strategic cooperation treaty with Iran in January.
The Kremlin said that the subject of Iran was touched upon during Russia-U.S. talks in Saudi Arabia last month.
"It was touched upon in Riyadh," Peskov said. "But not in detail, not in detail."
Asked specifically about the Bloomberg report, Peskov said: "Look, the topic of Iran was on the agenda, it was touched upon, but at the same time, not in detail."
