"The US military is planning to move US Navy ships and US military aircraft closer to Israel as a show of support, according to two U.S. officials familiar with the planning," NBC's Courtney Kube writes. "Movements could start immediately but all the assets will not be in place for several days."

Scenes at Israel's Ben Gurion  international airport have shown long lines of frantic Israelis, as well as tourists, seeking to exit the country amid fears of broader war and escalation following the major Saturday attack from Hamas and Islamic Jihad militants in Gaza.

Likely the coming days will see an exodus of tens of thousands of tourists as well as foreign nationals who reside in Israel. Dual Israeli nationals with places to stay abroad will also likely be seeking to get out.

NBC notes further that non-essential personnel may be leaving the US embassy in Jerusalem: 

The U.S. is also working through plans for a possible non-combatant evacuation — helping Americans get out of Israel. Nothing has been decided or ordered but they are working through options, including one that involves putting some Americans on the Navy ships to get them to safety.
