WASHINGTON: Hundreds of American citizens have departed Iran using land routes over the past week since hostilities broke out between Iran and Israel on June 13, according to an internal State Department cable.

While many left without problem, `numerous` citizens had faced `delays and harassment` while trying to exit, the cable said.

One unidentified family had reported that two US citizens attempting to leave Iran had been detained, it said.

The internal cable dated June 20 underscores the challenge Washington is facing in trying to protect and assist its citizens in a country with which it has no diplomatic relations and in a war in which the United States may soon get involved.

President Donald Trump and the White House said on Thursday he will decide in the next two weeks whether the US will get involved in the Israel-Iran war. Trump has kept the world guessing on his plans, veering from proposing aswift diplomatic solution to suggesting Washington might join the fighting on Israel`s side.

The air war began on June 13 when Israel attacked Iran and has alarmed a region that has been on edge since the start of the conflict inGazainOct2023.

Iran, which says its nuclear programme is peaceful, has retaliated with its own strikes on Israel. Iran is a party to the Nuclear Non-Proliferation Treaty, while Israel is not.

`Due to the limitations of US consular support in Iran, US citizens seeking departure should take advantage of existing means to leave Iran,` a State Department spokesperson said in comments emailed late on Friday, when asked about the cable, which was first reported by The Washington Post.

Potential evacuation The US State Department in a travel alert earlier on Friday urged its citizens wishing to depart Iran to use land routes via Azerbaijan, Armenia or Turkiye. Iranian airspace is closed.The US Embassy in the Turkmenistan capital of Ashgabat has requested entry for over 100 American citizens, but the Turkmenistan government has yet to give its approval, the cable said.

The Islamic Republic treats Iranian-US dual citizens solely as nationals of Iran, the State Department emphasised.

`US nationals are at significant risk of questioning, arrest and detention in Iran,` the alert said.

Washington is looking at ways to potentially evacuate its citizens from Israel, but it has almost no way of assisting Americans inside Iran. The two countries have had no diplomatic ties since the Iranian revolution in 1979.

US Ambassador to Israel Mike Huckabee on Thursday said the administration was looking at different ways to get US citizens out.

`We`re working to get military, commercial, charter flights and cruise ships for evac,` he said in an X post, urging US citizens and green card holders to complete an online form.-Reuters
