Two years of civil war in Sudan: how can the fighting end?

The civil war in Sudan, which broke out two years ago, has been described by aid agencies as the "worst humanitarian crisis in the world." Today, at a conference in London, delegations from European countries, the African Union, the United Arab Emirates and Egypt pledged to increased aid to Sudan, as well as try to find a pathway to peace. Also in the programme: the US Department of Education says it's freezing around $2.5 billion of federal funding to Harvard University, accusing the institution of fighting White House demands to combat left-wing bias at universities; and a 16th century book about cheese reveals details of Britain's long love affair with the dairy product.(Photo: A woman sits by the roadside after paramilitary Rapid Support Forces attacks on the Zamzam and Abu Shouk refugee camps, near the city of El-Fasher in Darfur.
