The UK, France, and Germany have announced new sanctions against Iran in response to its provision of ballistic missiles to Russia for use in Ukraine, including the suspension of all direct flights operated by Iran Air to the UK. The UK government emphasized that this decision follows repeated warnings to Tehran about its military support to Moscow, which is deemed a serious escalation threatening European security. US Secretary of State Antony Blinken confirmed that Iranian forces have trained Russians to use these missiles, which could be deployed against Ukraine imminently. Alongside the flight ban, coordinated sanctions target individuals and entities involved in the missile supply chain, including five Russian cargo vessels transporting military supplies. This coordinated effort signifies a united front among Western allies to pressure Iran to cease its military assistance to Russia. Both UK and US officials are set to visit Ukraine in a show of solidarity amidst ongoing tensions.
