The Sudanese army on Saturday refuted South Sudan's accusation of launching an air strike and a land attack on South Sudan's territory near the two countries' joint border, official SUNA news agency reported.

"These accusation is baseless and unjustified," the agency quoted Al-Sawarmy Khalid Saad, a Sudanese army spokesman, as saying.

"No Sudanese plane has launched any attack on South Sudan's territory because there are no battles between the two countries," he said. "Additionally, the Sudanese Armed Forces have withdrawn 10 km north into the Sudanese territory since the signing of a raft of agreements with South Sudan."

He further described South Sudan's accusation as "unacceptable, " noting that the agreements stipulate that such accusations must be referred to the monitoring committees which are entrusted with judging whether there are violations or not.

South Sudan's army spokesman Philip Aguer on Friday was reported to have accused the Sudanese army of launching the two attacks against South Sudanese areas near the joint border between the two countries.
