Thousands of youths loyal to South Sudanese rebel leader Riek Machar are marching on the strategic town of Bor, according to government sources.
Government troops are currently in control of Bor, the capital of Jonglei state they had taken from the rebels.
The government has offered to cease hostilities, but an army spokesman told the BBC that its forces were still battling over oilfields in the north.
At least 1,000 people have died since fighting broke out earlier this month.
