More than 200 Sudanese soldiers have defected from the army, accusing Khartoum of deliberately trying to destabilise the newly created country of South Sudan.
The group of troops, which arrived in the south carrying weapons in columns of trucks, say they defected after refusing orders to attack disputed oilfields in South Sudan's Upper Nile State.
The soldiers, most of whom were originally from South Sudan, say they are now ready to join the South Sudanese army, and fight against Sudan.
The defections came amid a growing border conflict mainly over oil-rich regions between the two countries.
