The reason for the sanctions is confirmed information that Iran has supplied missiles to the Russians.
Great Britain imposes new sanctions on three Iranian and four Russian parties. There are companies and organizations with connections to the drone industry in Iran and Russia.
The announcement came after the US Secretary of State confirmed that Russia has received ballistic missiles from Iran and will likely use them against Ukraine in the coming weeks.
The United States is also planning to impose new sanctions on Iran. Sanctions may be subject to e.g. airline Iran Air.
On Tuesday, France, Germany and Britain strongly condemned the delivery of Iranian missiles to the Russians and demanded that Iran immediately stop supporting Russia in the war.
