South Sudan caught in a cycle of violence

In South Sudan, more than fifty people, mostly women and children, were killed on Wednesday in continuing tit-for-tat attacks and cattle raids between the Lou Nuer and the Murle people in the state of Jonglei.

Aid agencies say more than 60,000 people have fled the violence and are in urgent need of humanitarian assistance.
