>> For the past five years, these two men have stood on opposing sides of a war that has killed tens of thousands of people. But on Sunday, South Sudan's President Salva Kiir and the country's former vice president and rebel leader Riek Machar sat side by side to sign a ceasefire agreement and power-sharing deal, hailing a new longed-for era of peace in the country.
>> It has imposed severe sufferings on our people.>> South Sudan became independent from Sudan in 2011, but just two years into its existence, civil war broke out. Fueled by personal and ethnic rivalries, the violence has displaced a quarter of South Sudan's 12 million population and ruined an economy that relies heavily on crude oil.
The signing ceremony took place in the Sudanese capital, Khartoum, and Sudan has helped broker the deal. On Sunday, Sudanese President Omar al-Bashir said South Sudan would stop pumping oil to Sudan in September. Previous peace agreements have held for only a few months before fighting resumed.>> Even if we sign beautiful agreements, and they're not implemented, we would have done nothing.
>> Kiir said he believes this deal will not collapse because it was not forced upon them like previous accords.
