South Sudan ceasefire monitor dies after officials held by rebels

ADDIS ABABA (Reuters) - A member of an East African regional body monitoring a ceasefire in South Sudan died of a heart attack after some monitors were detained by rebels to the north of the country, further complicating a peace process.

Ethiopia's Seyoum Mesfin, the chief mediator at the Inter Governmental Authority on Development (IGAD), which is trying to broker peace in South Sudan, said the rebels' action was a violation of the cessation of hostilities agreement signed by the two warring parties earlier this year.
