At least 411 government troops were killed by rebels on Monday after an attempt to recapture the city of Abu Karshola in South Kordofan State.
Sudanese Revolutionary Front or SRF military spokesman, Al Gadi Rumboy, says 44 prisoners were captured.He added that surviving government soldiers were forced to flee to the nearby cities of El Rahad and Umm Rawaba, in North Kordofan state.
Colonel Rumboy said the SRF forces also destroyed 37 military vehicles.
They captured a tracked armored vehicle and five large trucks, as well as 26 smaller vehicles loaded with weapons, ammunitions and other military equipment.
The Sudanese government could not comment on the issue.
Fighting in the North and South Kordofan states intensified following the failure of negotiations between the government and SPLM-North in the Ethiopian Capital Addis Ababa.
