WASHINGTON (Reuters) - The United States on Tuesday imposed sanctions on two people on opposing sides of the ethnic violence in South Sudan, showing the growing frustration in Washington with leaders in an African country it helped create.
Thousands of people have been killed and more than 1 million have fled their homes since fighting erupted in the world's newest nation in December between troops backing President Salva Kiir and soldiers loyal to his sacked deputy, Riek Machar.
