The US embassy in Israel has told some non-emergency staff that they can leave the country amid heightened concerns about the risk of war with Iran.
It comes a day after Washington and Tehran held talks widely seen as a last-ditch effort to avoid a conflict over Iran's nuclear ambitions.
The New York Times reported that US Ambassador to Israel Mike Huckabee told embassy staff in an email early on Friday that those wishing to leave "should do so TODAY".
He reportedly said there was "no need to panic, but for those desiring to leave, it's important to make plans to depart sooner rather than later".
It comes days after the US government ordered all non-essential staff to leave its embassy in the Lebanese capital of Beirut on Monday, after a security review.
Meanwhile, a number of countries including China, India and Canada have told their citizens to leave Iran as soon as possible due to the threat of hostilities.
US President Donald Trump has threatened military action against Tehran if it does not reach a deal about its nuclear programme.
He has ordered the largest US military build-up in the Middle East since the US-led invasion of Iraq in 2003, while Iran has vowed to respond to an attack with force.
Vice-President JD Vance told the Washington Post that strikes remain under consideration, but there was "no chance" of the US becoming involved in a drawn-out war.
Thursday's indirect talks in Geneva between the two countries resulted in "significant progress", mediator Oman said, adding that further negotiations would take place soon.
There has been no official response from the US, while Tehran hailed "good progress".
