A group of 150 U.S. Marines are poised and awaiting orders to enter South Sudan to help evacuate about 100 remaining citizens and provide security for the American embassy there. Around 380 citizens have already been evacuated amid a looming civil war in the world’s newest country, which in the last week has already seen hundreds dead and thousands more displaced. U.S. Africa Command cited as reason for the move, the lessons learned in Benghazi last year when three Americans and Ambassador Christopher Stevens were killed by militants. “We needed to be better postured, in order to respond to developing or crisis situations, if needed. These precautionary movements will allow us to do just that," the statement read.
