HONOLULU (AP) - President Barack Obama is telling Congress he may take further military action to protect Americans in violence-plagued South Sudan.
Obama says in a letter to Congress that about 46 U.S. troops were deployed Saturday to help evacuate Americans.
Four U.S. troops were injured in the evacuation mission when gunfire hit three military planes. All four are in stable condition.
Obama is on his annual vacation in Hawaii. He says he's monitoring the situation and may take more steps to ensure the security of Americans, U.S. property and the U.S. Embassy in Juba.
Fighting has continued Sunday in South Sudan, where the central government has lost control of the capital of a key oil-producing state. The unrest has raised fears of full-blown civil war.
