France, Germany, and the UK have introduced new sanctions on Iran for supplying ballistic missiles to Russia, which US secretary of state Antony Blinken said  will be used against Ukraine. The sanctions include restrictions on Iran Air and travel bans on military officials. UK foreign secretary David Lammy described Iran's actions as ‘a dangerous escalation’. Several individuals and organisations involved in the supply of the missiles face sanctions, and Russian cargo ships transporting these supplies have also been targeted. The Western nations have demanded that Iran halt its missile deliveries, citing security threats to Europe. Blinken and Lammy also flew to Ukraine to ‘hear directly from the leadership’ about their objectives. Volodymyr Zelensky has asked for authorisation to use Western-supplied missiles to strike targets inside Russia - a move the USA has so far resisted. Russia continues to make advances in eastern Ukraine.
