South SudanSouth Sudan's warring factions held preliminary meetings on Friday before the official start of talks in neighbouring Ethiopia, mediators said.  Dina Mufti, with EthiopiaEthiopia's foreign ministry, said the introductory meetings were necessary to bridge the groups' differences ahead of direct talks expected to start on Saturday. The meetings are being held at Addis Ababa's Sheraton hotel.  Both sides, meanwhile, continue to fight in the world's newest country.  The US embassy in Juba, the capital, said on Friday that the state department ordered a "further drawdown" of embassy personnel because of the "deteriorating security situation". An evacuation flight was being arranged.  South SudanSudan's government has declared a state of emergency in Unity and Jonglei, two states whose capitals are under rebel control. On Thursday, the central government warned that rebels loyal to the ousted vice-president Riek Machar were preparing to march the 74 miles to Juba from Bor, the capital of Jonglei state which has witnessed fierce fighting between government troops and rebels.  South Sudan's military said on Thursday it had sent reinforcements to Bor.  President Salva Kiir says the fighting was sparked by a coup attempt mounted by soldiers loyal to Machar on 15 December. But that account has been disputed by some officials of the ruling party who say the violence began when presidential guards from Kiir's Dinka ethnic group tried to disarm those from the Nuer group of Machar. From there, violence spread across the country, with forces loyal to Machar defecting and seizing territory from loyalist forces.  South Sudan has been plagued by ethnic tension and a power struggle within the ruling party, which escalated after Kiir dismissed Machar as his vice-president in July. The rebels back Machar, who is now a fugitive sought by the military.  South Sudan peacefully broke away from Sudan in 2011 following a 2005 peace deal. Before that, the south fought decades of war with Sudan.
