In South Sudan, President Salva Kiir and rebel leader Riek Machar have reached a peace deal aimed at ending South Sudan’s 5-year civil war, which has killed tens of thousands of people, displaced millions and pushed the country to the brink of famine. The conflict began in 2013 after President Kiir fired Machar, then serving as vice president. Under the new power-sharing agreement, Machar will return to power as one of five vice presidents.
