The U.S. Embassy in Jerusalem says the Donald Trump administration cannot guarantee the safety of Americans seeking to depart Israel following its war with Iran leading to the killing of the Asian country’s Supreme Leader Ayatollah Khamenei. 

“The U.S. Embassy is not in a position at this time to evacuate or directly assist Americans in departing Israel,” the statement said on Monday.

The embassy urged U.S. government employees and private citizens determined to travel out of Israel, despite the volatile security situation, to register for evacuation assistance with the Israeli Ministry of Tourism, which is operating shuttles to the Taba border crossing.

“The U.S. Embassy cannot make any recommendation (for or against) the Ministry of Tourism’s shuttle. If you choose to avail yourself of this option to depart, the U.S. government cannot guarantee your safety,” the statement added.

The U.S. government asked citizens to remain alert and seek refuge at bomb shelters “in the event of a red alert as security incidents, such as mortar, rocket, and missile fire, and unmanned aircraft system (UAS) intrusions, often take place without any warning.”
