Britain has imposed sanctions against Iranian individuals and organizations after Iran's attack on Israel on October 1, Britain's Foreign Office said on Monday.
The sanctions target senior figures in Iran's army, air force, and organizations linked to Iran's ballistic and cruise missile development.
"Despite repeated warnings, the dangerous actions of Iran and its proxies are driving further escalation in the Middle East," British Foreign Minister David Lammy said in a statement.
Holding Iran to account
"Following its ballistic missile attack on Israel, we are holding Iran to account and exposing those who facilitated these acts."
Lammy also discussed Iran's actions with European partners at the EU Foreign Affairs Council in Luxembourg earlier on Monday, the Foreign Office said.
Those sanctioned include Abdolrahim Mousavi, the Commander-in Chief of the Islamic Republic of Iran Army, the Farzanegan Propulsion Systems Design Bureau and the Iranian Space Agency.
Group of Seven (G7) nations, which includes Britain and the US, have condemned Iran's attack and urged for a de-escalation in the Middle East while reiterating their backing for Israel's security.
EU includes Iran Air in sanctions over missile transfer to Russia
The European Union also agreed on Monday to impose sanctions on seven people and seven organizations, including airline Iran Air, for their links to Iranian transfers of ballistic missiles to Russia.
The listings also include Saha Airlines, Mahan Air, and Iran's Deputy Defence Minister Seyed Hamzeh Ghalandari.
Last month, the United States, citing intelligence it said had been shared with allies, said Russia had received ballistic missiles from Iran for its war in Ukraine.
Washington imposed sanctions on ships and companies it said were involved in weapons transfers. Iran's President Masoud Pezeshkian said his government had not transferred any weapons to Russia since it took office in August.
Also facing sanctions under the EU move are prominent officials from the Islamic Revolutionary Guard and the managing directors of Iran Aircraft Manufacturing Industries and Aerospace Industries Organization.
The sanctions include an asset freeze and a travel ban to the European Union.
"Military assistance to an aggressor violates international law and the UN Charter. Those who support aggression must share responsibility and pay the price," Ukrainian Foreign Minister Andrii Sybiha said on X, welcoming the new sanctions.
