The Pentagon says Marines used a KC-130 cargo plane to evacuate about 20 Americans from the U.S. Embassy in Juba, South Sudan, in a move prompted by what the State Department calls a deteriorating security situation.

Pentagon spokesman Army Col. Steve Warren says the KC-130 flew from Entebbe, Uganda, on Friday, picked up the Americans and returned to Entebbe. He said that Two KC-130s made the trip but only one landed.

Warren also said the Pentagon believes it has sufficient personnel and assets in the region to respond to any further State Department requests for assistance in Juba.
