US warns Russia is giving Iran ‘unprecedented military and technical support’White House says Moscow moving toward full defense ‘partnership’ with Tehran, including air defense systems and fighter jets, in exchange for drones supplied for Ukraine warWASHINGTON (AP) — The Biden administration accused Russia on Friday of moving to provide advanced military assistance to Iran, including air defense systems, helicopters and fighter jets, part of deepening cooperation between the two nations as Tehran provides drones to support Vladimir Putin’s invasion of Ukraine.White House National Security Council spokesman John Kirby cited US intelligence assessments for the allegations, saying Russia was offering Iran “an unprecedented level of military and technical support that is transforming their relationship into a full-fledged defense partnership.”Kirby said Russia and Iran were considering standing up a drone assembly line in Russia for the Ukraine conflict, while Russia was training Iranian pilots on the Sukhoi Su-35 fighter and Iran could receive deliveries of the plane within the year.Kirby said the arms transfers were in violation of UN Security Council resolutions and that the US would be “using the tools at our disposal to expose and disrupt these activities.”Concerns about the “deepening and a burgeoning defense partnership” between Russia and Iran come as the Biden administration has repeatedly accused Iran of assisting Russia with its invasion of Ukraine.UK Foreign Secretary James Cleverly called the Iran-Russia collaboration a “desperate alliance.”“Iran is now one of Russia’s top military backers,” he said.The pact, known as the Joint Comprehensive Plan of Action or JCPOA, would provide Tehran with billions in sanctions relief in exchange for the country agreeing to roll back its nuclear program to the limits set by the 2015 deal."
