which officials have called a "precautionary measure". A statement by the Qatar government said the step was being taken "in response to the current regional tensions". This comes after US President Donald Trump said the US would take "very strong action" against Iran if the authorities execute anti-government protesters. Iran says it will retaliate if attacked by the US. According to rights groups, more than 2,400 anti-government demonstrators have been killed in the recent violent crackdown by the Iranian authorities.

The Qatar government said that it would continue to "implement all necessary measures to safeguard the security and safety of its citizens and residents as a top priority, including actions related to the protection of critical infrastructure and military facilities". Iran launched a missile attack on the Al-Udeid air base in June in what it said was retaliation for American strikes against its nuclear sites. A senior adviser to Iran's Supreme Leader Ayatollah Ali Khamenei warned Donald Trump on Wednesday that the June attack had demonstrated Iran's ability to respond to any attack.

"It would certainly help create a real understanding of Iran's will and capability to respond to any attack," Ali Shamkhani wrote in a post on X. The US has been threatening to intervene in Iran over the killing of protesters. On Tuesday, Trump wrote on his Truth Social platform that Iranian authorities would "pay a big price" for the killings, and urged people to "keep protesting". He has also said that Iranian leaders had called him and that "they want to negotiate" but that the US "may have to act before a meeting".

Iran's government has accused the US of seeking to "manufacture a pretext for military intervention", with the parliament speaker warning that if the US attacked, both Israeli and US military and shipping centres in the region would become legitimate targets. The latest protests in Iran began at the end of December following the collapse of the currency and as the country deals with soaring living costs. (BBC)
