Ghanian UN peacekeepers who have just arrived are standing at attention in Juba
Ghanian U.N. peacekeepers stand at attention upon arriving in Juba February 28, 2014. Fighting between troops loyal to President Salva Kiir and those backing the vice president he sacked in July, Riek Machar, erupted in mid-December. Thousands of people have been killed and more than half a million people have fled their homes, prompting the regional grouping of nations, IGAD, to initiate peace talks. More than 70,000 people have sought refuge at U.N. bases around the country after peacekeepers, in an unusual move, opened their gates to them.
