South Sudan's military says it is "a matter of time" before pro-government forces retake control of two state capitals from rebels.
Army spokesman Philip Aguer told VOA that soldiers backing former vice president Riek Machar control Bor in Jonglei state and Bentiu in oil-rich Unity state, but that the military is "capable of dealing with the rebellion."
He also accused fighters backing Machar of shooting at a U.S. aircraft that was evacuating citizens from Bor on Saturday. The U.S. military did not identify the shooters, but said four of its personnel were injured.
