President Barack Obama told Congress Sunday that he may take further military action to protect Americans trying to evacuate violence-plagued South Sudan.
In a letter to Congress, Obama said that about 46 U.S. troops were deployed Saturday to help evacuate Americans. That's in addition to another 45 troops deployed to reinforce the U.S. Embassy in Juba.
Four U.S. troops were injured in the evacuation mission Saturday when gunfire hit three military planes in Bor. All four are in stable condition, the White House said.
It remains unclear how many Americans are still stranded in Bor and other rural towns.
