South Sudan's warring parties committed to ending fighting and bringing their months-long conflict to an end without conditions, the chief mediator for the Intergovernmental Authority on Development (IGAD)regional African group, said Saturday after two days of talks in the Ethiopian capital.

Fighting erupted last December in South Sudan, which declared independence from Sudan in 2011, after months of political tension between President Salva Kiir and his sacked deputy, Riek Machar.

Seyoum Mesfin told reporters the IGAD bloc had agreed to freeze assets and impose travel bans, among other measures, on any party that violated the agreement.
