NAIROBI, Kenya (AP) — South Sudan’s military spokesman says there is increasing tension at a United Nations camp in the rebel-held city of Bor because armed elements have entered the congested area where the U.N. says about 17,000 civilians are seeking protection.

Col. Philip Aguer said South Sudanese troops are outside Bor and will soon advance on the city. Bor is controlled by troops loyal to the country’s former vice president. Aguer said troops will also soon advance on another rebel-held city, Bentiu, in the oil-rich region of Unity state.

The United States and Ethiopia are leading efforts to open peace talks on the 10-day-old crisis. Officials say President Salva Kiir and former Vice President Riek Machar have agreed to meet but specifics including the status of Machar’s imprisoned compatriots are holding up talks.
