On 18 August, at least 600 died in Uror county, Jonglei state, as Murle raiders attacked Lou Nuer villagers, in the latest in a series of raids and tit-for-tat attacks between the two groups that have left more than 1,000 dead since February. In grisly but illuminating symmetry, the UN said that around 26,000 cattle were stolen and 26,800 people displaced in the latest series of clashes.
