South Sudan to postpone presidential elections due in 2015, president says
Kiir and rebel leader Riek Machar, who was sacked as Kiir's deputy in July 2013, signed a new ceasefire agreement in Ethiopia on Friday and said they would hold further talks about forming an interim government to end nearly five months of bloodshed.
That plan got off to a shaky start as both sides swiftly accused each other of violating the truce.
