Americans warned by US Embassy in Israel to prepare for 'crises' amid Iran tensions

The U.S. Embassy in Jerusalem issued a security alert Wednesday reminding personnel and Americans in Israel of the embassy's standard advice. 

Also on Wednesday, the U.S. Embassy in Qatar issued a public notice telling citizens they can receive alerts and relevant updates from the Embassy in Qatar via WhatsApp.

"Leave Iran now. Have a plan for departing Iran that does not rely on U.S. government help," the U.S. Virtual Embassy Iran said on its website, suggesting land crossings into Armenia or Turkey if it is "safe to do so."
