Aid body pulls staff from S Sudan

Global aid organisation Oxfam has withdrawn 22 staff from South Sudan's Upper Nile state because of escalating violence along the newly independent country's tense border with the north.
Relations between the two countries have deteriorated sharply over the past week, due to fighting either side of the new frontier, including alleged cross-border attacks by the Sudanese army that Khartoum has strongly denied.
Oxfam staff reported bombing and heavy artillery for several hours on Friday in Upper Nile state, as well as planes flying overhead and a build-up of South Sudanese troops, in a statement released late on Saturday.
