U.S. aircraft hit by gunfire in South Sudan as conflict worsens

JUBA (Reuters) - Three U.S. aircraft came under fire from unidentified forces on Saturday while trying to evacuate Americans from a spiralling conflict in South Sudan. The U.S. military said four of its members were wounded in the attacks.

Nearly a week of fighting in South Sudan threatens to drag the world's newest country into a Dinka-Nuer ethnic civil war just two years after it won independence from Sudan with strong support from successive U.S. administrations.
