South Sudan troops 'recapture key oil city of Bentiu'
South Sudanese government forces have recaptured the oil hub of Bentiu from rebels, an army spokesman has told the BBC.
Col Philip Aguer said the final resistance - a tank protecting a bridge to the city - had been overcome at 14:30 local time (11:30 GMT).
The rebels have not commented.
UN peacekeeping chief Herve Ladsous says the conflict has killed "very substantially in excess" of 1,000 people since 15 December.
Ceasefire talks in neighbouring Ethiopia have stalled.
Bentiu is the capital of the oil-rich Unity state. The fighting has seen South Sudan's oil output fall by about 20%.
Col Aguer told Reuters news agency: "When you control Bentiu you control all the oil fields in Unity state."
Ahead of the government advance, thousands of people fled Bentiu, one of two main cities seized by rebel forces.
Several thousand have sought refuge in a UN base in the city, where people have been divided according to their ethnic group in order to prevent clashes.
The conflict has seen outbreaks of ethnic slaughter betweens Dinkas, the community of President Salva Kiir, and Nuers, like rebel leader Riek Machar.
The BBC's Andrew Harding in the South Sudan capital, Juba, says he understands that rebel forces withdrew from Bentiu ahead of the government advance.
He says the question now is whether its fall will prompt negotiators in Ethiopia to reach a ceasefire agreement to avoid further fighting.
Earlier, Col Aguer urged all civilians to leave Bentiu to avoid being caught in the crossfire.
"The earlier they leave, the better," he told the BBC's Outside Source programme.
He did not give any casualty figures but said that fighters on both sides had been killed.
