The United States hailed a ceasefire deal by South Sudan's president and rebel chief, urging both sides to swiftly implement its promises to end nearly five months of civil war.
"Today's agreement to immediately stop the fighting in South Sudan and to negotiate a transitional government could mark a breakthrough for the future of South Sudan," US Secretary of State John Kerry said in a statement.
"We urge both leaders to take immediate action now to ensure that this agreement is implemented in full and that armed groups on both sides adhere to its terms.
