Aerial bombardments, killings of civilians and house-to-house searches are escalating in the Northern Sudanese state of Southern Kordofan, aid workers and residents report. The UN Office for the Coordination of Humanitarian Affairs (OCHA) estimates that some 53,000 people have been displaced by fighting that broke out on 5 June near Kadugli, the state capital, between the Northern army, the Sudan Armed Forces (SAF), and former members of the Sudan People’s Liberation Army (SPLA).
