The United Kingdom has withdrawn remaining diplomatic staff from Iran as the conflict with the U.S. continues to escalate with a 12th night of airstrikes.

The Foreign Office of the United Kingdom (FCDO) stated on their website that, “Due to the security situation, UK staff have been temporarily withdrawn from Iran. Our embassy continues to operate remotely.”

The FCDO advises against all travel to Iran, saying British and dual British-Iranian residents face “significant risk of arrest, questioning or detention”.

The United States Central Command said late on Wednesday that the 12th night of attacks was designed to “further degrade Iran’s ability to threaten civilian mariners and commercial vessels transiting regional waters”.

Missiles struck near the cities of Ahvaz, Ramshir and Andimeshk in western Iran, according to Iranian state media.

Kuwait’s army said on X that the country’s air defences were “confronting attacks by hostile drones, following the sinful Iranian aggression”.

President Donald Trump had warned earlier that one bridge or power plant would be destroyed for each ship shot at by Iran in the Strait of Hormuz.

The Foreign Minister of Iran, Seyed Abbas Araghchi, said Iran would adopt an “eye for an eye” approach.

“Any aggression against Iran, including our infrastructure, will compel a powerful and decisive response,” he posted on X on Wednesday.

The 11th night of strikes on Iran into Wednesday saw air defences opening fire over the capital, Tehran.

Iran launched a missile attack on a Jordanian city while alerts were sounded in Bahrain and Saudi Arabia.

Tehran has responded to U.S. attacks by targeting energy infrastructure and desalination plants, which provide drinking water in neighbouring Gulf countries.

International law generally prohibits such attacks unless the infrastructure is being used for military purposes.
