David Shearer - South Sudan update

Former Labour leader David Shearer is into his second year leading the United Nations' mission in civil war-ravaged South Sudan from his base in the country's capital, Juba. The world's newest country, formed after independence in 2011, has not only been home to constant internecine conflict but also to extreme famine, the combined effect of which has killed hundreds of thousands of people and displaced an estimated 4 million. Aid agencies are now warning that South Sudan is on the brink of another devastating famine.
