JUBA, South Sudan (AP) - The U.N. says 34,000 people in South Sudan are seeking refuge at U.N. bases in three locations across the country. The U.N.'s humanitarian arm said Friday that 20,000 people are seeking shelter in the capital, Juba, while 14,000 are seeking shelter in Bor, the capital of Jonglei state, the scene of heavy violence this week. Several hundred people are seeking shelter in Bentiu, the capital of Unity State, where South Sudan's oil fields are concentrated. The U.S. Embassy was flying out a fifth emergency evacuation flight on Friday. A German plane was also scheduled to fly out. Violence broke out among South Sudan's presidential guard late Sunday night. Fighting spread across the country over the next several days, leading to fears of a civil war between ethnic groups.
