Sudanese war planes have launched renewed air strikes against South Sudan, violating a UN resolution to end weeks of a bitter border conflict. 'The Republic of Sudan has been randomly bombarding civilian areas,' said Southern army spokesperson Kella Kueth, who said the air strikes hit the border states of Upper Nile, Unity and Western Bahr el-Ghazal on Monday and Tuesday (7 and 8 May). It was not possible to independently confirm the reports of bombing and Sudan has repeatedly denied it has bombed the South.
