NNA  - South Sudan's President Salva Kiir has sacked the governor of northeastern Upper Nile state where clashes have escalated between government troops and an ethnic militia he accuses of allying with his rival and First Vice President Riek Machar.

The latest development compounds a confrontation between the two men that started after the White Army militia forced government troops to withdraw from the flashpoint town of Nasir near the Ethiopian border. -- Reuters
