South Sudanese President and opposition leader expected to meet in EthiopiaListen /
South Sudan's President and his main political rival are expected to meet on Friday in Ethiopia for talks on ending nearly five months of fighting.
The UN Secretary-General, who was in South Sudan on Tuesday, said this meeting is "absolutely necessary".
He held talks with President Salva Kiir and spoke on the telephone with his rival Dr. Riek Machar.
Ban said President Kiir and Dr Machar need to address the conflict through dialogue, in a peaceful way.
The two leaders' respective forces are locked in an increasingly brutal conflict since Dr Machar, the former deputy president, was forced out of office.
Mr Ban has said he is "strongly supporting" the willingness of President Kiir and Dr Machar to attend peace talks on Friday in the Ethiopian capital, Addis Ababa.
