Volodymyr Zelenskyy told NBC News it would be a “mistake” if American-made missile interceptors bound for Ukraine were diverted to Gulf countries being attacked by Iran.

Russia took satellite images of a U.S. air base in Saudi Arabia three times in the days before Iran attacked the site and wounded American troops, according to a summary of Ukrainian intelligence shared with NBC News by President Volodymyr Zelenskyy.

In an interview in the Gulf nation of Qatar on Saturday, Zelenskyy said he was “100%” confident Russia was sharing such intelligence with Iran to help target U.S. forces across the Middle East.

“I think that it’s in Russia’s interest to help Iranians. And I don’t believe — I know — that they share information,” he said. “Do they help Iranians? Of course. How many percent? One-hundred percent.”
