On Tuesday White House national security spokesman John Kirby urged that all Americans should leave Lebanon immediately while there are still flights. Two days of heavy Israeli airstrikes targeting especially Hezbollah strongholds of the south have killed at least 558 people and left 1,835 injured, according to the latest Lebanese Healthy Ministry figures. The situation is growing more urgent as the war comes to Beirut.
"We want to make sure that there are still commercial options available for Americans to leave, and they should be leaving now while those options are available," Kirby told ABC News.
