More than 120,000 people have been displaced by continuing violence in South Sudan, the United Nations says, and about half are sheltering at UN compounds.
The number of internally displaced people has been rising since fighting started on December 15 in the capital Juba, before spreading across the oil-producing East African nation.
Aid agencies need at least $166m to save lives, according to the UN, which has urged South Sudan’s leaders to start talks.
Regional leaders under a bloc called IGAD are meeting today in the Kenyan capital Nairobi to discuss the crisis.
The meeting is expected to produce a road map for peace talks between South Sudanese president Salva Kiir and the political rival he accuses of mounting a failed coup, Riek Machar.
