US tells Americans to leave Middle East, warns Iran 'unpredictable' amid rising tensions

The US State Department has issued a fresh security alert urging Americans in the Middle East to exercise heightened vigilance and consider departing the region, citing the potential for sudden escalation involving Iran.

The advisory, issued on August 1, warned that the security environment remains complex "with the potential for unforeseen escalation" and that Americans in the region should be prepared for flight cancellations, periodic airspace closures and other travel disruptions. It added that some airlines in the region have postponed the resumption of earlier flight schedules, while others have cancelled routes altogether.

US calls Iran 'unpredictable'


The State Department described the Iranian regime as unpredictable, pointing to recent strikes carried out without warning and to attacks expanding into areas not previously targeted, including Egypt. It cautioned that the absence of past attacks in a given country does not guarantee safety going forward.

The alert also flagged that US diplomatic facilities, including those outside the Middle East, have been targeted, and warned that Iran and groups aligned with it may target other US interests, businesses and institutions linked to Americans anywhere in the world.

Embassy staff already relocated in parts of the Gulf

Security alerts issued separately by US missions in the region echoed the advisory. The US embassy in Oman remains on authorised departure status, with some non-emergency government personnel relocated outside the country, though consular assistance continues to be available. In Saudi Arabia, the State Department had already ordered the departure of non-emergency US government employees and their families on March 8, 2026, citing safety risks.

What Americans abroad are being told

Americans in the Middle East have been advised to follow guidance from their nearest US embassy or consulate and to contact the State Department for information or assistance. Those outside the region have been told to seriously reconsider travel to and through it, and travellers who do move through the region have been asked to keep monitoring airport and airline operations.

The advisory comes against the backdrop of months of escalating conflict between Washington and Tehran. The US military carried out a heavy wave of airstrikes inside Iran in late July, days after Trump had paused the bombing campaign to give negotiations another chance.

Those strikes came in retaliation for an Iranian missile attack targeting a US base in Jordan. Trump had vowed a strong response at the time, saying, "We'll be hitting them hard. They're going to get a beating."
