"“This is a full-scale defense partnership that is harmful to Ukraine, to Iran’s neighbors, and to the international community,” White House National Security Council spokesperson John Kirby said."
"Iran is sending materials to Russia to help Moscow build a drone manufacturing plant that could be operational next year, part of a “deepening” military partnership between the two countries, the Biden administration said Friday. Officials also said that Tehran provided hundreds of armed drones to Russia last month for Moscow’s war in Ukraine.
Warning of growing defense ties between Iran and Russia, the Biden administration released a satellite photo of what it believes is the planned location of a drone production plant in the Alabuga special economic zone in the Russian republic of Tatarstan."
