The State Department on Friday recommended that U.S. citizens in Lebanon evacuate while flights are available due to an “unpredictable security situation” amid the escalating regional conflict.

“You should have a plan of action for crisis situations that does not rely on U.S. government assistance,” the statement read. “The best time to leave a country is before a crisis if at all possible.”

“There is no guarantee the U.S. government will evacuate private U.S. citizens and their family members in a crisis situation,” the statement added. “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. That includes transportation to points of departure.”
