WASHINGTON, Jan 31 (Reuters) - The United States on Tuesday put new trade restrictions on seven Iranian entities for producing drones that Russia has used to attack Ukraine, the U.S. Department of Commerce said. Iran's mission to the United Nations in New York said: "Sanctions have no effect on Iran's drone production capacity because its drones are all produced domestically. This is a strong indication that the drones shot down in Ukraine and using parts made by Western countries don't belong to Iran." In January, Canada announced it would buy a U.S.-made National Advanced Surface-to-Air Missile System (NASAMS) for Ukraine. The United States has provided two NASAMS to Ukraine and more are on the way.
