State Department urges U.S. citizens to leave more than a dozen Middle Eastern countries

The State Department urged Monday that all U.S. citizens leave more than a dozen Middle Eastern countries due to safety risks with the ongoing escalations that have slipped the region into significant chaos.

U.S. Assistant Secretary of State for Consular Affairs Mora Namdar posted on the social media site X that Americans in countries including Iran, Iraq, Jordan, Lebanon and Israel should "DEPART NOW" using any available commercial transportation.

The guidance comes as some major airlines have canceled flights to and from the region as the war that began when U.S. and Israel attacked Iran on Saturday. It has since grown into a wider regional conflict, touching nearly every country nearby.

The U.S. and Israel have continued to pound Iran since killing its Supreme Leader Ayatollah Ali Khamenei on Saturday, while Tehran and its allies have hit back against Israel, neighboring Gulf states, and targets critical to the world's production of oil and natural gas.

The intensity of the attacks and the lack of any apparent exit plan set the stage for a prolonged conflict with far-reaching consequences. Israel and the U.S. have given conflicting answers about what exactly the war's objectives are or what the endgame might be.

At least 555 people have been killed in Iran so far by the U.S.-Israeli campaign, the Iranian Red Crescent Society said, and more than 130 cities across the country have come under attack. In Israel, 11 people have been killed, with 31 in Lebanon, according to authorities.

The U.S. military announced Monday that two previously unaccounted for service members were confirmed dead, bringing the total American casualties during the operations against Iran up to six.
