The US Embassy in Lebanon once more requests that Americans depart the nation

Americans are being advised to "leave now, while commercial flights remain available, due to the unpredictable security situation," by the US Embassy in Lebanon.

A revised security advisory issued on Friday advised Americans who chose to remain in Lebanon to "have a plan of action for crisis situations that does not rely on U.S. government assistance" and included extensive guidance about the embassy's capabilities in an emergency.

“The best time to leave a country is before a crisis if at all possible. It is uncommon for civilian evacuations from a foreign nation to be aided by the US military. There is no guarantee the U.S. government will evacuate private U.S. citizens and their family members in a crisis situation,” the alert said.

“In the event that a U.S. military-assisted evacuation does occur, our focus will be on helping U.S. citizens. The U.S. government generally cannot provide in-country transportation during a crisis. It went on, "That includes transportation to points of departure."

The State Department upgraded its travel advice to Level 4—Don't travel—for Lebanon last week.
