The United States has imposed sanctions on companies and people it accused of producing or transferring Iranian drones that Russia has used to attack civilian infrastructure in Ukraine. The White House said last week that the United States is also considering ways to target Iran’s production of the unmanned weaponized aircraft through sanctions and export controls.
