South Sudan, Juba / July 9 2011. South Sudan became the 193rd country recognised by the UN and the 54th UN member state in Africa. Celebrations in Juba began at midnight. A countdown clock in the city centre reached zero and the new national anthem was played on television. The new country is rich in oil but one of the least developed countries in the world where one in seven children dies before the age of five. Unresolved disputes between the north and south particularly over the new border have also raised the possibility of renewed conflict.
