South Sudan's leader refuses to sign peace deal

Kiir said he needs 15 days before he will sign the agreement with rebel leader Riek Machar, according to mediators in the Ethiopian capital of Addis Ababa. Machar signed the accord before Kiir refused.

Some South Sudanese women who participated in the negotiations were seen crying after Kiir said he would not sign. Others banged tables to express their disappointment.
