The United States considered the two-week ceasefire announced by the Sudanese government in Sudan\'s Southern Kordofan as a \"positive initial step\" towards stability. \"This week\'s announcement by the Government of Sudan to establish a two-week unilateral ceasefire in Sudan\'s Southern Kordofan state is a positive initial step toward bringing stability and relief to those affected by violence since early June\", said State Department spokesperson Victoria Nuland in a statement late on Thursday. \"The United States strongly urges the Sudan People\'s Liberation Movement-North to show the same leadership and declare a two week ceasefire as well\", she added. Nuland noted that \"while we are encouraged by this announcement of a unilateral ceasefire and renewed discussions between the Government of Sudan and the Sudan People\'s Liberation Movement-North, the parties must immediately return to talks to agree to a full cessation of hostilities and a resolution of the political future of Southern Kordofan and Blue Nile\". \"The Government of Sudan must allow immediate and full access to humanitarian organizations so that they can provide much needed relief to the people of Southern Kordofan. We strongly urge both sides to refrain from using a ceasefire to strengthen any military positions\", she added. \"The United States supports the call by the United Nations High Commissioner for Human Rights for a full investigation of violations of human rights and international humanitarian law in Southern Kordofan. Those responsible for attacks on civilians must be held accountable for their actions\", concluded Nuland.
