Kerry warns S.Sudan factions of 'serious implications' if promises not met

US Secretary of State John Kerry warned South Sudan's warring factions Monday against walking away from ceasefire agreements and recently agreed peace talks, saying the implications of such a move would be "serious."

"Let me make clear: if there is a total refusal by one party or the other to engage into a legitimate promise which they agreed on..., not only might sanctions be engaged but there are other serious implications and possible consequences," he said on a visit to Angola.
