Sudan refuted on Monday South Sudan's accusations that the Sudanese army had moved into the south's territories, official SUNA news agency reported.

"The Sudanese armed forces are completely committed to the international borders as stipulated in the Comprehensive Peace Agreement," the agency quoted Al-Sawarmy Khalid Saad, Sudanese army spokesman, as saying.

"These claims tend to cover the violations of South Sudan's army of the cooperation agreement between the two countries," Saad said, pointing out that at the time when Sudan completed its withdrawal according to the agreements signed by the two countries, South Sudan's army is still present in six Sudanese areas.

Earlier on Monday, South Sudanese Information Minister Barnaba Benjamin reportedly accused the Sudanese army of encroaching on the south's territories, saying "the troops moved about 10 km into Upper Nile state."

He added that South Sudan would protest to the African Union and the United Nations regarding Sudan's decision to halt the exportation of its oil.

On Sunday, Sudan's National Intelligence and Security Service chief Mohamed Atta accused South Sudan of violating the cooperation agreement signed by the two countries in September last year.
