Violent clashes erupted in South Sudan Dec 15 between two military factions, one descending from the Dinka tribe to which President Salva Kiir Mayardit belongs, and the other descending from the Nuer tribe, to which former vice president Riek Machar belongs.
Machar is accused of plotting to topple the government.
The violence has spread from the South Sudan capital, Juba, where some 500 people are believed to have been killed, to other parts of the country.
UN Secretary-General Ban Ki-moon and other international leaders have demanded that South Sudan's political and military leaders immediately end all hostilities and stop targeted attacks on civilians.
The US Monday deployed 46 additional military personnel in South Sudan and President Barack Obama said his government may take further military action to support the security of its citizens in the country.
