"The White House said Tuesday that Russia's Wagner mercenary group plans to provide an air defense system to Lebanon's Hezbollah militants or to the regime in Tehran, as part of an "unprecedented defense cooperation" between the two US adversaries.
"Our information... indicates that Wagner, at the direction of the Russian government, was preparing to provide an air defense capability to either Hezbollah or Iran," National Security Council spokesman John Kirby told reporters."

"Russia could provide either Iran or Hezbollah, a U.S.-designated terrorist organization based in Lebanon, with air defense capabilities, the U.S. National Security Council warned on Tuesday.
Leaders in Moscow and Tehran have grown increasingly close over the last two years as Russia found itself isolated on a global scale following its invasion of Ukraine. During the war, Iran has provided Russia with hundreds of "kamikaze" drones, known as Shaheds, that they have used primarily to target Ukrainian infrastructure."
