Which countries are urging citizens to leave Iran amid US threat of force?

Multiple countries including Germany, India, South Korea, Australia, Poland, Serbia, and Sweden have issued urgent warnings to their citizens in Iran to leave immediately as tensions escalate between Washington and Tehran following US President Donald Trump's threats of military action in February 2026. The warnings come amid a massive US military build-up in the Middle East and rising diplomatic efforts to defuse the crisis over Iran's nuclear program. The escalating tensions follow President Trump's belligerent tone during his State of the Union address, where he accused Tehran of attempting to rebuild its nuclear program that was reportedly hit by US strikes the previous year. In response, the US has significantly increased its military presence in the region, deploying two of its largest aircraft carriers, the USS Abraham Lincoln and USS Gerald Ford, to the Mediterranean. Meanwhile, a third round of indirect talks between US and Iranian diplomats is scheduled for Thursday in Geneva, with international mediators attempting to prevent a potential conflict. Australia has urged its citizens to leave Iran 'as soon as possible,' citing the risk of arbitrary detention and the volatile regional security situation. Germany has described the security situation in Iran as 'extremely volatile and very tense,' warning that further military clashes cannot be ruled out. India has advised all its citizens in Iran, including students, pilgrims, and business owners, to 'exercise due caution' and leave by any means available. Polish Prime Minister Donald Tusk has gone as far as calling on Poles in Iran to 'please leave Iran immediately,' noting that 'the possibility of conflict is very real.' Serbia and Sweden have issued similar advisories, while South Korea has warned of 'rapidly escalating regional tensions' and called on all citizens to leave 'as soon as possible.' The United States has also taken precautionary measures by instructing all non-essential staff to withdraw from its embassy in Beirut, citing the need to 'reduce our footprint to essential personnel' while maintaining the embassy's operations. The move comes with concerns that the Lebanese armed group Hezbollah might react if the US attacks its ally Iran, potentially widening the conflict beyond Iran's borders.
